xue yue

I had the exact same issue, and lowering the "specular multiplier" on the light to ~0.95 solved the blue tint.

But good to know that it is resolved now.

Yes, the attributes of the new faces are taken from the second input of the boolean. Can't you just apply your UVs after the boolean in the way you want them to be? Same for all other attribs like Cd etc.

Not sure if I fully understand what exactly you want to to, but it is possible to stop vellum when you set @mass to 0. Or have you tried the @stopped or @dead attribute?
