Hi,
maybe this is a stupid question, but I cant find a shader where I can use a alpha Channel from a picture to make things transparent. I dive intro a “material shader builder” and can change the surface alpha to produce a alpha channel but I can't see objects behind. I've tried to add the picture to BSDF… but how?
Thanks

but that was the first I've done…. a opacity Map with no results. I took a TGA-file with an Apha Channel - wrong?

No; not wrong *if* you used the map's alpha channel to define the opacity ouput (Of). But you have to actually tell the shader to do that (a Texture VOP won't do it automatically for you, for example).
But setting opacity (Of) – whether from a map's alpha channel or somewhere else – is definitely the right thing to do.
