Oh ok so that was the use of that purple parameter then
I was wondering what was its use.

Thanks for your help I did what I wanted to. :wink:

Thanks for your example.
But I still got a question

I'd like to do everything in one shader.
I used a Mantra Surface in my example and I plugged my Alpha parameter in the Surface Opacity and in the Surface Alpha.
Is there a way to create a new output ? As if I wanted to call it Matte and plug into it my VOPSOP variable DestrMatte ?

Thanks

Thanks for your reply.
But since I already put my Alpha variable in the Opacity and in the alpha of my shader, can you tell me in which connection can I plug my DestrMatte variable ?

Thanks
