V-ray 3.4 - Matte shadow?

[omiKron]

Hi,

I'm using 3.4 Trial version and I want to know if there's a way to simulate shadows on HDRI map using the matte shadow plane technique, as it was in version 2, using Wrapper material.

Also, where can 2 sided material parameter be found?

Thanks!

I updated my tutorial on the matte wrapper material during the beta, hope this helps:

Very useful, thanks.

A single issue I'm having with it : the plane becomes transparent, but in the final render a slight grey transparent plane shows up, and the alpha contribution being set to -1.0 , alpha channel shows a plane with the matte shadow projected on it.

I believe you have to render with a black background, otherwise, the matte picks up the background.
