modify one color of a texture

Hi,
I’m trying to do something which ccan be very usefull in a lot of case but I don’t know how to start. I got a texture (UV texture form a graphist apply on an associated mesh).
I want in this texture modify all the black parts to change their color and give her a self-illuminated look, how can I do that ?
All leads, ideas or solutions are welcome :slight_smile:

Thanks in advance !

Yes just one color of my texture, only the black :slight_smile:

Look into AssetPostprocessor class. There are callbacks which are called before texture import and after. You have to set texture to readable and then you can simply do GetPixel and SutPixel (and don’t forget to call Apply).
