Material blending - Normals not blending properly?

RashedAlmetrami

Hey guys, created a simple material blend using a wooden and metal material but can't seem to get the normals to blend properly. Seems that only the normal from the base material shows through; hiding the normals from my wooden texture. 




Materials switched to showcase wooden normals (See in this case the wooden normal follows onto the trim)


Any ideas? As far as I can see it should be working?

This is the legacy way of doing layered materials, I would highly recommend to check out the new toolset included in 4.19. Much easier to use, and it makes things reuseable between material instances, which this method does not allow. Anyways, I checked out what "layer blend simple" does, by going inside the function, and it does not blend the normal attributes. It only blends base color, metallic, roughness, and emissive.

Good to know, thanks.

Gonna look into the paragon models and how they've incorporated it. Will post again in this thread if I have any success; just in case anyone else was curious

Using a 'MatLayerBlend_TenLayerBlend' node seams to have fixed the issue!

Check the instruction count now You should rather find or make a function that blends the normals too in a way that you want. Or better yet, make it for the new blending system.

Switched out the 'MatLayerBlend_Simple' nodes for 'MatLayerBlend_Standard' which incorporates the normals into the blend
