3DS MAX, AUTOCAD, AND NAVISWORKS CLOUD RENDERING IMPROVEMENTS

The same improvements in quality and speed that were released for Revit cloud
rendering a few months ago are now available for 3ds Max, AutoCAD, and
Navisworks users.

 

Here is a brief summary of the improvements

 * New path-tracer engine
 * New more efficient denoiser
 * Better global illumination and area lights
 * Faster rendering times (see also frame-splitting below)
 * New post-processing tools
 * New progressive preview for Panoramas and Solar studies

 

Her is a Link to the original release for Revit renderings:
https://autodesk360rendering.typepad.com/blog/2018/12/rendering-engine-improvements.html

A link to a later adjustment to address noise in transparent surfaces.

LIMITATIONS


AUTODESK GENERIC MATERIAL

Avoid using Autodesk Generic as a transparent material as the correct behavior
has never been defined and different applications will provide different or even
wrong results.

Use Glazing or Solid glass for consistent and accurate results between local and
cloud rendering.


3DS MAX

 * Autodesk Solid Glass material - The previous cloud renderer incorrectly
   calculated the glass absorption, resulting in an exaggerated transparency.
   That is now fixed, so your glass will render much darker. Keep in mind that
   the color you specify is the absorption expected at 6mm, so adjust it
   accordingly to compensate for thicker or thinner glass panels.
 * The cloud rendering uses more advanced materials shaders and exposure
   techniques, so renderings submitted with Native exposure can look different.
   Adjust the exposure on the web Gallery Post Process or use Advanced exposure.
 * Colors with one or more RGB values set to 0 are unrealistic and if the
   exposure is adjusted to slightly overexpose the image you will see some color
   shifting for those materials.
 * Bump Amount when using procedural maps is not well defined. It might appear
   too intense or not intense enough in the cloud compared to local rendering.
 * Roughness implementation is different. For values other than 0.0 and 1.0 the
   amount of roughness will appear different.


AUTOCAD

 * There is an issue with the field of view, and in some cases renderings might
   see a wider or narrower view angle than what was intended. We are working on
   a fix.


NAVISWORKS

 * Navisworks projects can be very large and fail to render because of memory
   limits in the cloud rendering nodes. We have a fallback procedure that
   re-tries failed jobs on the largest possible machines we have available, but
   that might also fail in some cases. We will evaluate possible memory
   reduction techniques over time and release updates when ready.

CLOUD RENDERING FRAME-SPLITTING

We updated our cloud rendering and introduced a powerful frame-splitting
feature.

 

This feature is automatic and will affect any single image (regular rendering or
illuminance) over a specific size. You will not have to do anything.

 

If the image is large enough to trigger this new feature, your rendering will be
split into crops to be processed in parallel on multiple nodes for a much faster
rendering.

 

Once all the parts are completed, the image will be recombined and result in a
single frame as any other rendering job.

 

The only thing you will notice is that the progress preview will show the crops
rendered at different stages of completion.

 



 

You might also notice that near the end of the rendering, when all the crops are
completed, some edges will be still visible due to differences in exposure for
each crop. A final refresh will then show the whole image again, this time with
a uniform exposure.

 

The frame size at which splitting will occur and the order of the crops is
subject to changes. If many crops seems to be waiting in queue (white), just let
the service scale up and more and more crops will then be rendered
simultaneously.

 

You can expect significant rendering time improvements. A large frame can be
split into a dozen or more crops and the total render time can be an order of
magnitude less.

 

For illuminance renderings, the full illuminance scale cannot be determined
until all crops are completed, so you will see different scales for each crop,
and only at the end the scale will be recomputed and the full frame rescaled.

 



SERVICE PERFORMANCE CONSIDERATIONS

Frame-splitting is now enabled for Revit and Fusion 360 single images only, for
all users. This includes regular renderings, and illuminance (for Revit).

 

Other products (3ds Max, Navisworks, AutoCAD) and image types (Panoramas, Solar
Studies, etc) won’t take advantage of this feature.

 

After a period of service monitoring, we might adjust frame-splitting
parameters, and add support of other products or image types.

LATEST UPDATES | REVIT CLOUD RENDERING

January 20, 2019

 * We have released a new version of our cloud renderer with significant
   reduction in noise especially on see-through glass.

The change affects renderings in Standard and Final quality.

In the example below, rendered as Final, you can see how the concrete textures
and glass surfaces now render without noise. Shadows of thin objects also are
much more defined.

Before (200% size) After (200% size)

We are working on more improvement on noise reduction. We expect more tweaking
to better manage noise in some fringe cases.

 

January 4, 2019

 * We made some changes to the way some materials use Tint. Previously, the Tint
   parameter was ignored or applied inconsistently.
   
   * For materials of type Generic (Non-Metallic highlights), Solid Glass, and
     Glazing: Tint now applies to the Color (diffuse and/or transmission), but
     not to the Highlights.
   * For materials of type Metal and Generic (Metallic highlights): Tint now
     applies to Color and Highlights.
 * We increased some quality parameters to minimize noise on transparent
   materials. We are still working on a more comprehensive fix for this issue.

REVIT CLOUD RENDERING IMPROVEMENTS

We are happy to announce the significant improvements made to the Autodesk Revit
Cloud Rendering, which have been released on Dec 9th, 2018. 

The new version of our cloud rendering engine improves on quality and fixes old
issues. As many old projects might have been tuned to look right with the old
version of the engine, you will notice that new rendering will look different.

As the new version is more strictly photoreal and relies on correct inputs
(especially materials settings), some adjustment to old projects might be
necessary to get the best results.

We suggest using the new Revit material types (especially for mirrors, metals,
and glazing) and to follow the guidelines reported below whenever possible.


 


FEATURE IMPROVEMENT

 1. Quality improvements with new rendering engine

 * There are significant improvements in quality in some scenes, both standard
   and final. A newly added denoising algorithm can often produce noise-free
   renderings in cases where the previous algorithm would show noise even in
   "final" quality.

Standard Quality Before Standard Quality After

 

 2. Materials Appearance Consistency with Revit in-product

 * The cloud renderer used to have a different implementation of legacy
   materials (which originate from Mental Ray) than the in-product Revit
   renderer. This is now fixed, and both in-product and cloud are based on the
   same shader codebase. Any remaining mismatches are likely to be due to data
   translation issues, not shader differences; please report them as bugs.

   Before    After   In Product

 

 * If the new physically based Revit materials are used instead (Revit 2019 or
   later)， local and cloud rendering should always match.
 * Documentation about the new physically based materials is available here:
   * Full documentation
   * Introductory document

 

 3. Lights enhancement

 * The previous rendering engine had a corner darkening issue. In new
   renderings, this problem is fixed.

Before After

 

 * The previous rendering engine had problems with area lighting close to other
   surface, causing light splotches. This problem is gone now.

Before After

 * Note, several bugs have been fixed in the cloud renderer that have not yet
   been ported back to Revit. This will still lead to some differences and will
   be fixed in a later version of Revit. Until then, the cloud result should be
   treated as correct.

 

 4. Water Wave Height

 * Old water materials will have an incorrect Wave Height because their settings
   were unitless. Exaggerated water surface can be easily fixed editing the
   material. There is no specific rule on how much the Wave Height value should
   be lowered. Set it to what looks right for your scene.

Default wave height Reduced wave height

 

 5. Scenes with no lights

 * Rendering a scene with no lights (closed room with no artificial lights) now
   renders a black image instead of flat colors.

Before After

 

 6. Panoramas

 * Panoramas no longer support the solid color background option, but you can
   download a panorama image with Alpha channel and add the desired solid color
   background in an image editing application.

 

 7. Emissive decals

 * In the meantime, emissive images like monitors can be achieved using the new
   Revit physically based opaque material. This guarantees that they are
   physically accurate and much more realistic.

Before After With Opaque emissive material

 8. IES web orientation

 * We fixed an issue that was causing IES webs to be rotated in the wrong
   direction. Be aware that re-rendering old files you might get different
   lighting.

 

 9. Missing textures behavior

 * Missing textures will now be replaced by a black color instead of white. The
   Revit exporter, before uploading the processed scene for rendering, warns you
   about the textures that were not found. Make sure you check the list and
   understand that materials using those textures will not be able to use them.
 * When rendering locally, the missing texture behavior might differ.

 

 10. Performance

 * The new service will show a significant increase in performance for rendering
   jobs with many frames (especially solar study, stereo panorama). These frames
   are now distributed to separate cloud nodes for rendering, instead of
   rendering sequentially on a single node.

 

 11. New Post Processing tool

 * A new image post-processing widget replaces Exposure Adjustment and adds
   several features.

Old UI New UI

 * A few preset curves are provided, providing a simple way to switch between
   looks: linear, neutral, mild and vivid. A custom curve can still be chosen,
   by manually setting the highlights, midtones and shadows parameters from the
   previous version of the widget.

Linear Neutral Mild Vivid

 

 * A new bloom effect is very useful to achieve additional realism, by
   simulating low-frequency light leaking between pixels, an effect common in
   real cameras and human eyes. The true brightness of over-exposed areas (e.g.
   windows, light sources and specular highlights) can be made more obvious
   using this effect.



 

 * Color correction and color preservation can now be turned on and off
   explicitly. Keeping them off is recommended and often looks better unless a
   specific look is desired.
 * We have also improved the look of the automatic (“Advanced”) exposure.

 

 12. Viewer changes for multi-frames renderings

 * When view the in-progress rendering of multi-frames rendering like Solar
   Study and Turntable rendering, the viewer supports to show progressive
   rendering for each frame.

Old UI New UI

 

 13. Download menu for solar study

 * New option to enable download of Solar study as video.

Old UI New UI


 


LIMITATIONS AND BEST PRACTICES

 

 14. Overlapping geometry

 * If you see circular artifacts on surfaces, it’s probably because there is
   overlapping geometry. Make sure your walls, ceilings, floors, glazing is not
   duplicated or intersecting. When overlapping geometry occurs, the renderer
   can’t consistently pick the material of one or the other surface.



 

 15. Coincident lights geometry

 * Placing a light shape coincident to a light fixture geometry can cause
   artifacts or missing light emission or visibility. Make sure you separate the
   light a bit to avoid this issue.
 * Other issues could arise if the light is put behind a translucent, frosted,
   or semi-transparent material, as the renderer will have a hard time resolving
   paths to the light. Place the light in front and use a lightly emissive
   material for the shade behind it.

 

 16. Point lights visible in reflections

 * If you use point lights throughout your scene to add a certain amount of
   ambient light, those lights will appear in reflections on mirrors and glass
   surfaces.
 * We suggest removing those lights and add real lights, as the renderer is
   strictly photoreal. After rendering you can adjust the exposure to bring up
   the mid-tones and brighten up the scene.

Before After

 

 17. Panorama and Stereo Panorama rendering

 * The progressive rendering preview will not show all frames always. It will
   show the frames that are in progress or completed. If the advanced exposure
   has been set, the progressive preview will have different exposure with final
   one.

Progressive Preview One side of the cube rendering is still in progress, while
the other two are complete.

 

Progressive Preview (Advanced exposure) Final (Advanced exposure) Each side of
the cube rendering has a slightly different exposure.

In the final rendering, the exposure is unified.

IMPROVED USER EXPERIENCE ON RENDERING WEBSITE

Based on the input for many of our customers, we added some cool, new features
on the Rendering website, which makes it easier to browse through your
renderings and get panorama outputs in various formats. Here are the details.

Rendering quality indicator -  Since the thumbnail of an image is really small,
it was difficult to distinguish between final and standard quality renderings.
We have now added a small diamond icon on the right hand corner which indicates
that this is a final quality image. It makes selecting and previewing your
images easier, especially when you have a large number of renderings for a
project. 





Download or delete multiple jobs - We added the ability to select multiple
images from the thumbnail panel. When you hover over a thumbnail, you'll see a
circle icon that can be checked. Once you check multiple thumbnails, you can
choose to either download or delete them. There is also an option to "Select
All".

Please note that only completed renderings can be selected using this method.
In-progress renderings cannot be selected. Also, if you choose to download a lot
of images, the download process will be significantly longer.



 

Download panoramas and stereo panoramas in various 360 formats. When you choose
a panorama and click on the Download UI, the dropdown menu shows various 360
formats available for download. This was requested by many of our customers, who
want to use panoramas across various devices.



 

Equirectangular format (Spherical)



 

Cross format



 

Strip format

CONNECTED PANORAMAS USING CLOUD RENDERING

Many of our rendering customers have asked us for a way of connecting various
stereo panorama renderings, to get a connected, immersive VR experience. You can
do this now using Autodesk Cloud Rendering and Autodesk Project Play.

See this example of connected stereo panoramas that we created -
https://play.autodesk.com/pub/au2016pano View this on your mobile phone with VR
glasses (like cardboard) for a complete VR experience.

Here are the steps for creating your own connected experience. 

1. Render stereo panoramas - First, render stereo panorama renderings that you
would like to connect with each other using Cloud rendering. It is a good idea
to create preview renderings first and test your lighting, materials and
cameras. Then render the views in final quality at 1536 px resolution. Do not
render larger than that since most cell phones may not be able to handle large
resolution files. 




2. Download panorama - Once your panoramas are rendered, download panorama as a
zip file. 



 

3. Prepare images - The only file you need for Play is image.png. This is a high
resolution image with two rows - one is the right eye image and the other is the
left eye image. You have to slice this image into 12 individual JPG images and
label them 0.jpg to 11.jpg. You can do this with any image editing software that
you prefer, like Photoshop. You can also use ImageMagick to this in an automated
way.

ImageMagick instructions.

 * Download and install ImageMagick depending on your operating system.
 * Open up your command-line console.
 * Navigate to the folder where you put your image.png
 * Run the command: convert image.png -crop 1536x1536 %d.jpg (Note: if convert
   does not work, use magick image.png -crop 1536x1536 %d.jpg) 
 * Once done, it should produce the 12 images that you need. 


  

4. Link panoramas - In order to link these panoramas together, use Autodesk
Project Play. Here are detailed instructions for doing that.

Let us know how this works for you in your VR projects.

DOWNLOAD STEREO PANORAMA FOR GEARVR

Since many Rendering customers have been asking for this, I'm happy to let all
of you know that we have added Download Stereo Pano for GearVR as an option for
stereo panorama renderings. If you want to view your stereo panoramas on GearVR,
you no longer need to process the images using ImageMagick and run scripts. We
have simplified the process. In order to use this,

 * Render a stereo panorama.
 * Go to My Renderings, click on the thumbnail and choose "Download Stereo Pano
   for GearVR"
 * A zip file is downloaded to your computer containing the image file and .json
   file. You can rename the files, if needed. 
 * Please note that  if you have rendered a large size stereo panorama, it will
   take a long time to process and download. 
 * Copy these files to your Samsung phone's media folder. 



Remember that, if you want all the original files, you can "Download Stereo-Pano
as Zip".

Have fun rendering and viewing your images on Samsung GearVR.
