The use backdrop color feature in the LW fog crash LWtoA. The LW fog shader doesn't work with Arnold 4.2.3. Crash evaluating Arnold surfaces with LightWave nodes like the "Instance Info". If you need to modify texture while you are rendering, you can use the "Flush Caches" command available in the main LWtoA menu bar. Difference in microfacet BTDFs: Rough refraction viewed at grazing angles or using Phong-smoothed normals renders slightly darker now, especially for high roughness values. SSS with zero diffusion radius: previously such shaders would render black, now the result is the same as a diffuse BRDF. Previously no compositing would happen for this channel, and just the value from the first surface hit would be reported (irrespective of the particular AOV being set or not) RGBA AOV composition: The A channel of RGBA AOVs is now fully composed as an additional alpha channel per AOV. Full-frame spherical and cylindrical cameras: Spherical and cylindrical cameras now maintain their FOV vertically regardless of frame and pixel aspect ratio.

Raised minimum Windows version to Windows 7: We no longer support Windows versions before Windows 7 and Windows Server 2008 R2 The options.texture_max_open_files is now set by default to 0, which means that the maximum number of texture files that can be simultaneously opened is automatically computed by Arnold using a new heuristic. The only reason to tweak this parameter was to get a tiny speedup at the cost of lower quality, faceted curves this tiny speedup is now dwarfed by the more significant ray/curves speed gains found in this release. The max_subdivs attribute of the curves node has been hardcoded to 6 (the previous default) and removed. The global option enable_aov_composition no longer had any effect on performance so it has been removed and now compositing of semi-transparent AOVs is always performed correctly. Removed "enable aov composition" feature. aaPhysicalSky is no longer supported by the developer and it doesn't work with the last Arnold core. The aaPhysicalSky light has been removed.
