Creating a transparent sign...

leo04

I have an image..."png format"... with a transparent background.

I have looked and not found anything in the forums to suggest how to do this...but basically I want to add the image to a surface with the background transparent.

Anyone have a suggestion on how to do this?

I have started by creating a cube....

Thanks.

Do you want the surface itself to be transparent? If so then convert your PNG into 2 separate JPGs, one which is basically a copy of your PNG, the other which serves as a mask with black corresponding to the transparent area and white to the opaque area (See attachment). Set the first as the Diffuse image in the Surfaces tab, and the second as the Opacity image.

You might want to use a plane primitive instead of a cube primitive, so your image is only in one place (the plane) rather than being scattered across all 6 sides of the cube.
