see png alpha

[clankill3r]

I use a png as texture, now how can i see the alpha of the png?
Now it's just grey and black.

If you DONT want to use HQV double click your material node and under the "OpenGL" display tab select the "use alpha as mask option".

In the example below you see this working on a simple constant shader with a noIcon image, which has alpha...

thanks! works like a champ!

in the render it's black
Does anyone know how to render it out correct?

I use Arnold, but a solution for mental ray is aslo welcome.

Arnold doesnt have a transparency from alpha checkbox like regular SI shaders. Therefore you should create a new image (you can plug it to the same texture node) and enably "Alpha to RGB" option, than use that for opacity...
