Hi,
I’m new to unreal and I would like to make a material where the blend operate like this

With a clear separation between the two diffuse.
For the moment my blend got this blur
I would like the bricks to appear fully or not at all, or at least remove this blur which don’t look natural at all…
Here is my material
I hope I was clear enough.
I looked on the web and everything I found was mainly about landscape blending
Thank you for taking the time to read this question.
