![]() ARNOLD-11568ĪOV denoising with the OptiX denoiser: Upgraded from the Optix 6 to Optix 7 denoiser. In one test we saw a 10% performance improvement. Faster bloom imager: The bloom imager has been optimized.Note that bloom and denoising imagers require access to all pixels and so will not benefit from this optimization. This likely will be most noticed when interacting in IPR with small buckets. The exposure and tonemap imagers, for instance, are now significantly faster. Faster per-pixel imagers: We removed overhead in imagers that can execute independently on each pixel.On a 128-core machine we saw about an 8x speedup. Faster TextureResolveUseExistingTx: The TextureResolveUseExistingTx stage is now much faster when many threads are trying to open textures for the first time with the use existing tx option enabled.Updated Alembic to 1.8.3: The alembic procedural has been upgraded to use version 1.8.3 of the alembic library.Surface materials defined in a nodegraph are now supported. Updated MaterialX to 1.38.3: We now use MaterialX 1.38.3.This can be observed with kick -o, which will now work for different case types. Case insensitive output image file extension: AiFindDriverType() is now case insensitive, so asking, for instance, for a "png", "PNG", or "Png" will all return the png driver.
