#2

Use the merge operator or the layer blend modes

#3

Thanx I get all right now exprect Mask, do you know how I can get it?

#4

A trouble:twisted:, I believe you can simulate the divide using the invert operator and using the blend mode “color dodge” in the merge operator
link of tutorial?

#5

Didn’t work :frowning:

tutorial: http://www.spot3d.com/vray/help/VRayHelp150beta/tutorials_anim.htm

#6

it would have to function, you tried switch the inputs ?
the math of color dodge is divide for the inverse of the second input, if you invert the footage before the node you it will get a divide mode.

#7

It worked now :slight_smile: thanx:

#8

I don´t know about Vray, but isn´t more easy to render in different layers or render matte passes to the objects?
