In this release we generally improve render speed over v3.08, and fix a number of issues that were reported for the previous RC.
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.
Changes since OctaneRender 4 RC2:
- Fixed max cores being set in the preferences window when unchanged.
- Fixed artefacts when using high roughness on brdfs other than Octane.
- Fixed displacement crash on some meshes, mostly alembic.
- Added diffuse, refraction, reflection filters for universal material.
- When manually compressing textures, these can now be saved as compressed also.
- Fixed Beckmann sampling for the specular case.
- Fixed universal material wrongly modifying roughness when transmission or metallic is greater than 0.
- Fixed some artefacts in compressed textures.
- Fixed some memory not being deallocated sometimes when using AI Light.
- Some performance optimizations for AI Light processing
- UI improvements for the image tiles texture node.
- Fixed loading of Y/chroma EXR images
- Speed up loading of .hdr files
- Fixed universal material when using thin film interference with coating layer.
- Added support for handling compressed images in the Lua API.
- Fixed a bug that caused the render priority selection in device dialog to not do anything.
- Improved how Octane deals with running out of memory, which fixes some cases where caching fails and then a render failure occurs.
- A small volume rendering performance improvement of between 5-10%.
- Fixed camera presets when there are volumes in the scene and some meshes are changed in the viewport using eg gizmos.
- Fixed a significant performance regression from 3.08, where scenes with hundreds of unique meshes rendered significantly slower.
- Render speed improvements - in general v4 is now faster than v3, and info channel kernels are between 15-25% faster.
- Fixed internal connections being inconsistent when collapsing nodegraphs into a node pin.
- Fixes and improvements for handling large nodes in the node graph editor: multi-connect now has a scrolling panel, and allows searching in the list of input pins. You can now expand pins by Ctrl-dragging items out of their pins.
- Inside node graphs you can use ctrl+drag to create input and output linker nodes
- Node graphs with a single output pin can now be collapsed.
- Restored shortcut keys for collapsing and expanding.
- Fixed a rare render failure when modifying meshes in the viewport either in scatter/placement, or with gizmos.
- Fixed a permanent hang and a render failure when using emission on displacement triangles
- Re-did performance tuning for all compute capabilities.
- Fixed crash caused by invalid primitives with emission.
- We no longer distribute the cuDNN library with Octane - when octane first loads, we download cuDNN if it has changed.
- Fixed universal material rendering on backfaces.
