!!Closing my post, since I've found another way to render my projects.!!

Sure.

Are you importing the PNG as a Texture or as an Image? Do you have a picture of the outcome?

I import the png as an image, because if I choose texture, it will fill out the entire surface.

This is what it looks like before and after render.

Hi folks.

I have a question to a problem you've probably encountered before, but somehow I can't find any solution when I google it. The problem is, I get a black background on my PNG's when I render my project.

I hope one of you can tell me what I do wrong.

My plan is to make a plastic wall with a logo on it.

Here's what I do.

1. I start out by creating an infinite plane.
2. Then I create a box from a rectangle and push/pull.
3. I select it and make it into a group.
4. While highlighted, I go into the VRay asset editor and choosing the "Plastic Simple Shiny Black", changing it to another color in diffuse, under the VRayBRDF section, and then apply the material to the selection.
5. Then I import a PNG with transparent background onto the face of the box.
6. After that I go for the render.

Any ideas what I do wrong?

Kind regards
Paul
