alpha cut out opacity?

[davegmac]

I am trying to set up the shaders for my trees but I cannot get the leaves cut out with the alphas. What is the process? I have used RGBA, Stencil, and transparency amount but none work.

All of these methods should work, but they apply to MODO's material only - RGBA, Stencil and transparency won't work with the V-Ray material. Maybe I should add support for RGBA and Stencil
to work with the V-Ray material, haven't thought about that. You can seen an example of the Stencil being used for leaves in the "Maple" scene from the modo samples / Proxy.

For the V-Ray material there is a separate texture effect called "vmtl Opacity" that is the opposite of MODO's transparency effect. You can use it.

Ok, Thanks. I was't thinking tat I should use Modo mats and was converting everthing.

Hello Vladimir,

can you make an automatic invert for the stencil if they render with a modo material?
Currently you have to manually invert the stencil of the leaves to render correct in vray :0)

I don't think I understand what you mean.
The stencil effect should work fine in V-Ray, if you are using the MODO material.
The stencil effect does not affect the V-Ray material at all, at least for now.

Hi Vladimir,

I´m sorry my bad! Just tested the tree again and it seems to render fine now!
