Massive LAG with Max 2020.2 and Substance2

This might be better addressed with Autodesk or Allegorithmic and I will, but I wanted to see if anyone is having a LAG in Max 2020.2 when using a ‘Substance2’ material with VRay Next?

I create a plane object.
I create a Substance2.
I attach a generic fabric .sbsar.
I use the script to generate a VRay material.
I drag it to the plane.

Instantly, my scene is massively lagged. Just disabling or enabling the checkmark for say, the ‘bump’ parameter takes 15-seconds. Anything I touch takes 10-15 seconds or longer. If I now drag a standard VRay Mtl to the plane, all is well.

Hello! I’ve tried to replicate you scenario here with 3ds Max 2020 upadte 2 and Substance 2, but it seems to work just fine. Are you using the latest Allegorithmic plugin? Is it reproducible with Sibstance to VRay script only?

Best,
Tanya

Thanks Tanya, yea, it looks like I’m alone on this. Before I went and did a lengthy uninstall and reinstall of Max and then reconfigured my user settings, I wanted to see if it was happening elsewhere. I must have a conflict somewhere. I’ve already tried a new ENU and that didn’t help.

I appreciate your having weighed in for me.
