Conceptual renderings

[Fëanor]

Hi everyone!

I'm trying to do some conceptual renders in vray using transparencies, but have a lot of artifacts, like you can see in the image here.

The method I use is to set the refraction IOR to 1, and I've tried increasing the subdivs, teh max depth, I've tried with affect alpha and shadows on and off... and anyway I try it I get that ugly noise in the parts where two objects touch each other.

Using the default scanline in max doesn't have those problems, so maybe I'm setting anything wrong?

 

thanks a lot, and excuse my broken english.

you can post your material?

Sure, here it is... you never encountered that problem?

It could be that your camera's near-clip is set too low. Try adjusting that or moving the offending surfaces apart slightly.

I would second the movement to split the edges. Basically what you are getting is the same problem that causes co-planer faces to render black. Since your objects are touching the edges occupy exactly the same location and the renderer can't figure out which object to display. This isn't a problem with opaque objects, but when you add the transparency then you can see every edge. A mere 1/8" spacing or so on your objects would solve the problem.
