I’m trying to do some work on an aircraft I’m working on for MSFS and every time I open up the material editor to add a material, 3ds max just crashes…I’m on the latest version of the SDK and 3ds max plugin but so far no luck with a crashless max…going to try a reinstall of the plugin, but I’m not very faithful that it will work 
if anybody has any issue similar to this, or had this issue them selves, and have fixed it, please do let me know! Cheers 
I get this with 3DS 2021, which is why I’ve reverted to 2019. (Not tried 2020.) It would be great to have a stable 2021, though!
Same here… glad I read this… now I am installing 2019… gah…
