Today I am happy to finally announce the release of Cycles for Max version Beta 3.00. This release brings support for several new features from Cycles in Blender 2.80 including combined CPU/GPU rendering, random walk subsurface scattering, improved memory usage during renders, and more. You can find the full changelog and a download link on the download page.
Importantly, this release includes changes to how Cycles interprets the "roughness" value on a number of shaders. These changes may cause your materials to render differently in this new version of the plugin. See the Breaking Changes section of the manual for more details.
Unfortunately I wasn't able to get all of the new features I wanted ready in time for this release. I intend to make a followup release later this month that will include more Blender 2.80 features including the principled volume shader, principled hair shader, bevel shader, more nodes for the node editor, and a shader exporter compatible with Blender 2.80.
Along with this release I have also added another render by Claudio Magrì to the gallery.
