[solved] object with alpha, equivalent to Vray's alpha contribution??

[tom182]

Hi, I want to render out a studio shot but want background drape to to black in the alpha channel, I can do this easily in Vray, >vray properties of object and set alpha contr. to -1.
how can this be done in Corona please ?

Well, I found the solution for studio setup (as for other things simpler than for vray) in this forum topic...
You can download the scene and analize how things are done...

saw this earlier but its for C4D, I'm a Max head,

I'm pretty sure this is easily done in Corona -
****EDIT update **** - just figured it out- set alpha mode in materials options, even easier than VRay method ;-)
