OctaneRender™ 3.0 for Houdini™ - production build 3.03.4.0

[juanjgon]

Hi!

This is the latest production build of OctaneRender™ 3.0 for Houdini™. This 3.03.4.0 release is available for the Houdini 13.0/14.0/15.0/15.5 last production builds for Windows x64, Linux gcc4.8 and OSX 10.10. This plugin is also compatible with Houdini 15.5 Indie. In this case the plugin will have a 1080p limited resolution while rendering sequence, and the scene export and cloud rendering features disabled.

New features
A list of all the new features is provided here: viewtopic.php?f=33&t=51679
The plugin manual is going to be updated in the next weeks to cover most of the changes. https://docs.otoy.com/manuals/products/houdini/v3/


=============================================
RELEASE 3.03.4.0
=============================================

* NEW PLUGIN FEATURES:
- Support of the new H15.5.565 production build
- The beauty pass in the multilayer EXR files has now the standard "RGBA" channel names.

* OCTANE BUGS FIXED:
- Fixed incorrect fallback to the primary environment when the visible environment is black.
- Fixed volume bounding box sometimes casting a shadow when using environment medium.
- Fixed occasional kernel hang during the displacement intersection test, usually resulting in the that the OS kills the graphics driver and lots of CUDA error messages are dumped to the log.
- Fixed infinite loop that sometimes occurs in scenes with lots of transparent surfaces.
- Fixed ray-sphere intersection for rays starting inside the sphere.
- Fixed occasional issue with PMC seeding resulting in inconsistent brightness in animations.
- Fixed incorrect weighting of render layer passes in areas where blurry/transparent objects of the active layer lie in front of the inactive layer (see viewtopic.php?f=30&t=55903 ).
- Fixed some baking artifacts caused by disagreement between geometric normals and smooth normals (see viewtopic.php?p=284803#p284803 ).
- Fixed the tangent normal pass, which was only displaying perturbations along the U axis.
- Fixed crash in deep pixel rendering when the film size is smaller than the maximum tile size (which is rounded up to a multiple of 4 in each dimension).
- Fixed incorrect size of temporary tone map result buffers. This should help with tone mapping renderings with huge resolution.
- Fixed swapped tone mapping behaviour when HDR image are saved via the viewport save drop-down.

Thanks!
was the half precision issue fixed in this build?

Yes, it should be. I've tested this feature using this build without problems so far, but if you find this problem again, please let me know with a sample scene to test it here.

Thanks,

[WhyGee]

I'll check. thanks!

Hi Juanjo ,
I just updated to this release ( 3.03.4.0 ) and I have a nasty error message : "Failed to export render passes discrete files"
It worked just fine just before the update ( with version 3.03.2.1) .
I tried with png or exr output, all the same.

Has something changed in the pass rendering system ?

Weird. Do you have the half precision option enabled? There is an internal change in the Octane API, but I've not seen any problem with it yet.

Can you send to me the full log file and/or a scene to reproduce the problem here?

Thanks,

No, Ididn't have the half precision option enabled.
Sending you the scene is bit of a pain for now ( I might try to reproduce the problem starting with an empty scene ).
But I switched to MulitLayer EXR files, which works perfectly. ( no error message anymore )
and nicely enough ,having updated octane got rid of a nasty one pixel border I had when compositing a shadow pass . Nice !

[juanjgon]

OK. I'll try to reproduce this problem here anyway ... if you can reproduce it in a simple scene, let me know.

Thanks,
-Juanjo

[juanjgon]

I can reproduce this problem here. Investigating ...
