OctaneRender™ 4.0 for Houdini™ - beta build 4.00.0.9 RC2 Tweet

[juanjgon]

Hi!

This is a new build of the OctaneRender™ 4.0 for Houdini™ plugin compiled with the Octane 4.00 RC2 core. This release is available for the Houdini 15.5/16.0/16.5 latest production builds on Windows x64, Linux gcc4.8 and OSX 10.11. This plugin is also compatible with Houdini 15.5/16.0/16.5 Indie. In this case, the plugin will have a 4k limited resolution while rendering sequences, and the scene export and cloud rendering features disabled.

Important notes:
- Please note that this build will expire in 120 days.
- As before, some introductory material on V4 can be found here: viewtopic.php?f=33&t=66013
- Whilst we have reached the feature lock milestone, we consider this a non-stable release, as we expect to stabilize in preparation for the first stable. Until then, please do not use this for production purposes.
- Please make sure you have NVIDIA driver 387 or newer on Windows and Linux, and any CUDA driver for Mac that supports CUDA 9.1. Please also note that architecture improvements mean we can no longer support Fermi GPUs.

=============================================
RELEASE 4.00.0.9 RC2
=============================================

* PLUGIN BUGS FIXED:
- "Create intermediate directories" enabled by default.
- Fixed a crash while working with the MPlay IPR.
- The Octane lights mesh is no longer rendered if the light shader is disabled.

* OCTANE FEATURES:
- Light linking and global light exclusion. New spare params and render target options to configure the light masks.
- Added UDIM support using the new "Texture Image UDIM" node.
- Updated universal material. This means the universal material is now complete.
- Out of core geometry and textures is now automatic, you don't need to set any VRAM limits for these anymore. If enabled in preferences, Octane will automatically start using system memory when VRAM runs out.
- Reinstated network rendering, without AI Light updates, which is being finalized.
- Improved processing speed for AI Light.
- AI Light now works with sphere emitters.
- Improved AI Light processing performance.
- Small reduction in memory consumption when using AI Light.
- Added ability to capture direct and/or indirect light for light passes.
- Added near clip plane support for Z depth pass.
- Added options in texture and blackbody emission nodes to keep emissive power constant when applying uniform scaling (if surface brightness is disabled).
- New volumetric AI denoiser.
- New GPU texture compression options in the texture nodes.
- New option in the texture nodes to import of individual layer from multi-layer EXR.

* OCTANE BUGS FIXED:
- Fixed denoiser blend option not working properly when using hot pixel filter.
- Fixed render failure when denoiser output render pass is enabled, and the denoiser is disabled in the imager node.
- Fixed layer shadow pass.
- Increased the maximum number of OSL nodes in one texture node tree from 500 to approximately 30,000.
- Fixed crash when rendering some meshes that have multiple materials where one or more have displacement.
- Fixed a bug where alpha values were written into the output image buffer when the alpha channel was disabled.
- Fixed two problems with the render layer shadow pass: shadows when there was no emitter, and shadow strengths being incorrect.
- Fixed crashes when rendering simple scenes that contain an emitter.
- Fixed render failure on some simple meshes.
- Fixed render failure on some meshes that happens after caching is complete.
- Fixed incorrect memory consumption reporting sometimes.
- Fixed a possible hang when using AI Light and modifying other settings.
- Fixed a crash when using AI Light in a scene with no emitters.
- Fixed render failures when AI Light processing is interrupted with either emission changes or other changes in the scene.
- Fixed some extra memory consumption when switching from a scene with emitters to one that has none.
- Fixed a case where device memory stats returns total memory as unavailable memory.
- Fixed a crash when using AI Light if all lights in the scene have a sample rate of zero.
- Fixed a case where SSS data is accidentally added into the transmission pass.
- Fixed AI Light crash if an emitter is moved immediately before mesh caching begins.
- Fixed clay mode for universal materials.
- Fixed normal passes to record incorrectly sometimes.
- Fixed the export of raw buffers when the resolution is not a multiple of 4.
- Fixed a crash and incorrect motion blur that happens sometimes when making changes in placement nodes.
- Fixed handling of int[2] and int[3] input parameters for OSL shaders.
- Fixed a very random render failure.
- Fixed AI Light update for Network Render.
- Fixed baking camera.
- Fixed a GGX sampling error.
- Nishita sky: Fixed some very bright sunlight from Nishita sky model when the sun is just below the horizon.
- Planetary environment: Improved appearance of star field
- Planetary environment: Fixed rendering of sunset at high altitudes
- Added an approximation for ozone absorption to the planetary environment.
- Fixed a crash on the roughness info pass.
- Fixed a crash when attempting to render hairs with zero vertices.
- Fixed rendering of meshes with an opacity map inside the environment medium.
- Fixed crash due to (unsupported) AVX instructions in the denoiser.
- Fixed crash due to failing to page-lock the result buffer of the denoiser.
- Fixed crash in the denoiser if the film resolution is not a multiple of 4.
- Fixed render failure if the scene doesn't contain instances.
- Fixed a network render crash when AI light is disabled.
- Fixed incorrect UV mapping of on-the-fly compressed image textures.
- Fixed artefacts in some image compresison formats (when done on-the-fly).
- Fixed missing Volta support on OSX.


Enjoy it!

Thanks juanjgon.
Enjoy your holiday as mush as possible.

After few hours working on this version :

- Fixed a crash while working with the MPlay IPR.

Working like a charm after 10 hours working on it on 4000*4000 resolutions, not a single crash.
Thanks you Juan.

When you will work on the 2d pan and 2d zoom for opengl window in future versions if could investigate on resolution larger than screen window too.
Thanks again for your work.
