Could someone enlighten me with setting up a material based on Substance created textures? My efforts are way to glossy or look rubbery
Were would _metallic usually go?
I not that clued up on Blenders nodes so I'd thought I'd ask

Substance usually creates textures like this. these gamma values should be also set in blender nodes, expect normal, that does it for you

Basecolor - srgb/gamma2.2
Roughness - gamma 1
Metallic - gamma1
Normal - gamma 1
Height - gamma 1

All technical maps are linear. Color is in srgb just because it is easier to work with like this.

Metallic map can be used in mix material node to mask materials. I did some testing some time ago and I got fairly similar results with substance without any major tweaking.

It seems a bit weird to me that your metallic map is pure white?

Awesome, thank you I will give it a go


I have a load of tiles which have this white texture, that's why I was a bit confused how to use it

I would do it like in the attached screenshot.

However, I'm a bit unsure about the roughness texture. The roughness input of the disney principled shader is not linear (for better artist control), so if this texture was created for a disney shader, it will not match when used on LuxCore materials. You'd have to use a band texture to map it back to linear in this case (see the disney paper for the specific formula they use for their roughness input).

In Thea the metallic is a layer mask.. kinda useless with it being pure white, the lower layer does nothing

Thanks guys I'm giving it try now
