In this release we fixed several issues that have been reported. Starting from this release, we no longer include cuDNN in the Octane download due to its size. Octane will now download it once automatically when started.
Please note that this build will expire in 120 days, this is now shown on the bottom right of the Standalone release.
If this is the first time you use V4, you can find some introductory material on V4 here: first release post of V4.
Whilst we have reached the feature lock milestone, we consider this a non-stable release, as we expect to stabilise 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.
EDIT: There have been various reports that the Linux and OSX builds crash during startup after the cuDNN library got downloaded and installed. We hope to have found and fixed the issue and updated the OSX and Linux release builds accordingly.
Changes since OctaneRender 4 RC3:
When starting Octane for the first time, you'll see the following window: EDIT:
Occasionally when we upgrade cuDNN, you may see this again at a later date. You can simply click Download and Octane will download the file needed. If you have any trouble with this process please let us know. If you need to, you can manually download the file and copy it into "C:\Users\<user name>\AppData\Local\OctaneRender\thirdparty\cudnn_7_0_5" folder so all octane builds (standalone and plugins) can load it or in a particular build folder(eg: standalone installation folder), but only that particular build can load it.
If you need to download the files directly yourself, we include links here for convenience:
cudnn64_7.dll for Windows
libcudnn.7.dylib for Mac OSX
libcudnn.so.7.0.5 for Linux
- Image tiles texture node will now work for displacement.
- Texture compression will no longer block the user interface, but when starting render, any compression jobs will complete before rendering begins.
- Fixed incorrect behaviour when more than 64 render passes are enabled, which also caused a lot of error messages.
- Fixed texture preview.
- Fixed a crash when loading very small images.
- Fixed light linking passes 7 and 8.
- Fixed volume rendering when there are multiple volumes in the scene.
- Fixed some specular material differences from 3.08.
- Fixed universal material special case when BRDF is not Octane BRDF, IOR is 1.0, transmission is 1.0, with black diffuse.
- Fixed denoise results when affect alpha option is enabled .
- Fixed AI Light with animated triangles in the scene.
- Fixed random colour texture.
- Fixed a performance issue when using direct light kernel with a medium or volume where absorption is very low.
- Improve OSL compiler performance.
- Lua API: fix print() for node graphs.
- Fixed an issue when exporting scatter nodes to FBX.
- Fixed denoiser output when using affect alpha without an alpha channel.
- Fixed a case where network render GPU count was incorrect.
