Texturing Images without an Alpha

I have an image of a white text character on a black background, the image has no alpha channel. Is there a way to texture this image onto a polygon so that only the white character is drawn, i.e. ignoring the black pixels of the image.


You can use the blend unit to mix based on color brightness.


There are other ways that might attempt to map the image to the alpha channel either with shaders or using a specific alpha texture format.

Thanks very much for the quick reply dorbie, I’ll give that a go.
