Frame buffer jumps on region render

You can disable plugins from the Plug-in Manager in 3ds Max (Customize>Plug-in manager). Not sure if hiding would be enough, you may try though.

Ok awesome thanks - good to know. I've never used that before.

So after much testing and emailing the very helpful team at Itoo, it turns out it's a FP/RC issue with the Multitexture map. I swapped out all of the said maps with Railclone Color maps and it solved the hanging.

Hope this helps anyone else who may have this issue.
