A quick update as it has been a while since I posted anything to this website.
Work is continuing on the next release of this plugin and I expect a release to be ready very shortly. This upcoming release will be the biggest so far in terms of bug fixes. It will also bring the plugin up to parity with Blender 2.81.
If you would like to try out this new version ahead of release, you can join the Cycles for Max discord here. I will occasionally post preview releases including new features there.
I have also recently posted the Blender shader exporter to github, you can follow development here.
In other news, I'll be doing a major update to the server powering this website within a few days. The site may be down for a couple hours or as much as a day if something goes wrong, but I do promise it will come back.
Feb 14 Edit: The server upgrade has now been completed. Expect no further downtime in the near future.
