Running Phoenix from an Arbitrary Location - Phoenix for 3ds Max - Global Site
There’s an issue with the path which was “Chaos Group” for 3ds Max 2024 and now is just Program Files Chaos for 3ds Max 2025+
Also it’s not clear but I believe necessary that the \Phoenix3dsMax2025\ needs to be copied into the Autodesk_Plugins apth, not just the contents of that folder.
Lastly.. this webpage here is titled “Vray for Blender, Beta”. Weird.
