[Solved] Looking for cheap dirt effect

[chichiFregiLover]

Hello, what’s the cheapest way to add a dirt effect to a mesh. I’m not looking for something complex, just a dust variation on walls. it may cover large meshes so i’m not sure decals are the good way to do. I tried the macro variation thing, but for some reason it doesn’t work on a vector 3. it works on an image texture, but not on a vector 3

Can you show your material? ( where you try to do dirt on a V3 ).

i said V3, but it seems actually it’s a V4. as the conversion to parameter turned it into a V4

You can still do it, same way dirt is always done.

Gimme 5…
