This is another release candidate fixing various issues in the materials as well as the material preview rendering. We really hope that this is the last one and we can get the stable version out next week.
As mentioned in the previous release, we are still looking at various stability issues, especially one issue that was reported by various users where Octane rendering fails with spurious CUDA error 2 (out of memory). It seems to happen at specific points during the scene initialization phase but during CUDA calls that don't allocate any memory. For the one scenario where we could reproduce the issue, we have found a workaround to "fix" it, but since it might be just some obscure side-effect of some other problem, it might pop up again in some other scenario. I.e. we need more data from users and more failure cases and any help by you is very much appreciated.
Please note that this build will expire in 120 days, this is now shown on the bottom right of the Standalone release.
As before, some introductory material on V4 can be found here: first release post of V4.
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 RC 6:
- Added option to the batch render script and job to allow saving of both the main and the denoised main passes (see viewtopic.php?p=348116#p348116).
- Fixed broken preview rendering if the main render module hasn't been initialized yet (see for example here: viewtopic.php?p=348636#p348636).
- Fixed darkening of the planar material preview rendering when a glossy, meetal or universal material is being rendered.
- Fixed artifacts in the sheen / coating layers of the universal material (see viewtopic.php?p=347984#p347984).
- Fixed fireflies when sheen and coating are both enabled in the universal material.
- Fixed clear coat of universal material to have no effect if its IOR is 1.
- Fixed energy gain at glancing angles when the clear coat roughness is low.
- Fixed excessive usage of system memory during the compilation of heavily overlapping geometry.
- OSL: Added support for specifying a step size for integer inputs via the
sensitivity
metadata. - Standalone: Fixed incorrect progress bar updates on Windows 10.
- Standalone: Reimplemented rotation handle which now allows you to rotate objects multiple times around the picked axis.
- Lua: Added
octane.project.setSelection()
which clears the current selection and selects the given node items and pins.
