Thank you Jon, I’ll take a look at this !

I’ve notice that my technique slows down the rendering when those “transperent” object are in front of each other, your hint might correct this.

Since my workflow doesn’t need randomizing big arrays of objects but only light emitters at the moment, the slowdown wasn’t a real problem but any improvement to this method is well apreciated !

For VRay, a speedup would be to put an empty VRayMtlWrapper or VRayBlend material in the NULL slot, rather than a VRayMtl with 0 opacity and 1.0 IOR. Other render engines have similar ways to make a null material (empty mental ray material, e.g.).

Nice one, very helpfull. I’d also use the tile texture to ad variations to the windows.

I think the solution is quite simple. Once you got the random effect you desire, you can add a edit mesh modifier, select elements by mat ID number corresponding to the void material then simply delete the elements. Finally, it will be like selecting randomly the elements, function that doesn’t exist natively in MAX…
