Hello, I'm looking to use the following texture(berlin_wall_brick_colorful)  to blend with (berlin_wall_concrete_holes_splat2) that's available in radiant. But there is no "blend" version of these textures, how can I make a blend version of either texture?
From quick google searches, I believe I will have to utilize asset manager? I have no other idea about how to take an in game texture and make a blend version of it.
 
If not possible, how else would I go about blending these two textures?
 
Please advise!
Thanks!
