VRam used twice in plugin. Serious issue.

[Karba]

Karba I can do so. But it would be a large download due the amount of project data. Basically you could set up a scene by yourself and monitor the load. It will double as soon as the scene is loaded by the plugin. If it exceeds the viewport will stay black and do nothing.

Isn't there a way to kick the textures 3dmax uses out of the VRAM before the plugin starts rendering?

I don't know, unfortunately. I think one of possible ways is not to show textures in 3dsmax viewports.
