Hi. This should be very simple I guess. Let’s say I have a normal map for a muscular, old and wrinkly, skinny and ripped or whatever type of body and I want to scale the effect with a constant in material instances from barely visible to extreme. I guess it’s a kind of contrast I need. I tried simp…

thats because normal maps are normalized, meaning the 3D vectors that the image describes will always be unit vectors, with a length of 1. so if you multiply all the channels by 1000, they are still proportionally the same, and get normalized back to 1. its like you are scaling the vectors, but not …

Thanks a lot! I always suspected there was a reason why normal maps are so colorful. That’s one mystery solved.

I’ve got a follow up question. How would you blend two normal textures together without having them decrease their “intensity”? I mean, if I have a normal map for muscular and one for old, and I want to be able to scale their effects more or less independently from zero to one, how should I go abou…

Thanks again :slight_smile: I will try that.

Hi guys, I’m desperately searching for a slow transitory between two normal maps. Your example is the only one that me closer to what I want. Can someone help me please?

Isn’t the normal map blending, like posted by ScottSpadea in the pictures below, exactly what you are looking for?

It’s a lot easier to simply mask the Red and Green channels from your normal then Multiply this by a scalar value (Normal Strength) and then Append back on a value of 1 for the blue channel. [image]

TorQueMoD You will get a different result than original normal map by doing this with NormalStrenght=1 I would not recommend this method. You will get a better result by scaling a blue channel and normalization.

Material: Scale "Strength" of Normal Map?
