Ok now
The problem is not unreal:
Lerp, multiply, add, roughness, opacity whatever
Is in unreal, Photoshop, unity, lightwave, maxon, Babylon, 3Ds Max and all of them
Is a waste of time to make materials, unless is your job
No one use it, people use master materials, 85% of studios uses substance
When I create a material I use mixer and blender using smart materials and udim
If you know about materials it doesn’t matter the software so… read the book
You don’t learn because You don’t want to do
