I am creating this post for the purpose of asking a question about texture masks. As an experiment, I created a model and a UV map to work along with it.
The UV map for the model looks like this:
Now once I added color to it within my paint program, imported the model and texture into Unreal, and created a material, I realized that I would not be able to use pre-made textures in the UV texture. To compare, I opened up the material for the starter content chair asset. I became aware that the base texture was strikingly different from what I had. If you have not seen the base texture for the chair, this is it:
I learned that the texture for the chair is a texture mask. However, I still have yet to find documentation or a tutorial that explains how to make a texture mask. Which brings me to my question. Is it possible to create a texture mask from a pre-made UV map texture? If so, I would greatly appreciate an explanation on how it is done.
Thank you for your time.
