Here comes the first release of a new development cycle towards 1.20.
There have been some major changes in Octane which cause it to run a lot slower on pre-Fermi GPUs
(with compute model < 2.0). PMC and the matte material still don't work on these GPUs either. We
also have major issues building the CUDA kernels for these old GPUs, which is why we had to remove
the support for compute model 1.0. It's is becoming more and more likely that we have to discontinue
support for pre-Fermi GPUs in the not too distant future.
Changes since 1.10:
- Added architectural glass as option "fake_shadows" in the specular material node
- Improved direct light calculation in SSS materials - as a side effect volumetric noises don't work anymore
- Improved accuracy of intersecting volumes with different IORs
- New multi-threaded mesh compilation with better render performance and lower memory usage during compilation (/voxelization)
- New dirt texture node
- New panoramic camera node
- New wire-frame mode in the deep channel kernel
- New PMC kernel option "parallelism" that reduces the number of samples that are investigated in parallel, to make caustics appear earlier at the expense of some performance
- Improved daylight system
- Black edges in glossy materials are fixed
- Surfaces with a matte material hiding all objects behind, but are visible indirectly
- Improved combining of noisy multi-GPU results, which resulted in too dark images in the past
- Several bug fixes in the new OBJ parser
- Bug fixes in the render framework
- Default caustic blur in render kernels is now 0.01
