Hello everybody, I switched to 3DS Max 2022, Just a negative feedback under this version and not the least. I have put the Plugins in the correct folder, in the plugin management it is marked loaded. The big downside is that on a new scene the material "RW Material" does not appear in the "Materials" category. On the other hand, when we open an existing scene of a lower 3DS max version ex: 2019 So I can't find a solution to this problem. It was just to keep the community informed. Regards Christophe
