Render button won't work

V-Ray V-Ray for 3ds Max General
1

I’ve got a particular Evermotion scene that I’m messing around with. A couple of issues:

I can render the scene as DR via Backburner, but if I try to render (with or without DR) on my workstation, the Render button turns yellow when clicked, but otherwise does nothing. I’ve tried resetting the Renderer to 3.40.02. I’ve also tried reassigning the Renderer to Mental Ray. Still nothing.

Second issue is that the Material Editor will not reset. It resets the materials, but the material balls don’t come up. Just grey squares. But if I click on a square, I’ll see a VRayMtl and a diffuse color. Other scenes seem just fine. Not sure if there’s a “lock” or something that’s checked.

Thanks.

I wonder if saving a render preset and merging everything into a new scene with the same system units would get around this.

It looks like a broken scene, do you know the versions of V-Ray and 3dsMax which the scene was original built with?
Did you try to merge the scene and render preset as Deflaminis suggested?
