MAT lookup?

Postby GavinG » Sat Aug 17, 2019 6:04 pm

I have an image which has a coloured object and a black background. I am sending this image into a constant MAT. Is there a way for the material to use the coloured object from the image as the material, and ignore the black background?

If you mean remove parts of the geometry based on the texture, then you'll want to use the Discard pixels based on alpha feature thats on the common page of the MAT. If will create aliased results though, so you may want to use a Anti Alias TOP after that to clean it up.
