Bump and spec maps

IgnitionChemistry

I've applied both normal and specular maps to my mesh, and when I ticked 'decal' under material properties, to activate them (as I was told to), some of the faces have gone invisible, or inside out... it leaves some of the areas more detail but messes the mesh... how do I fix this?



Thanks in advance

The Decal checkbox in the material settings are more for the floating planes that accompany a mesh, like leak stains, holes, etc.

It looks like you applied it to the stone material, which isn't really a floating plane or anything. If you do have those floaters, make sure you separate them in a sub-material so the Decal checkbox is only checked on the Decal material only.

Got it, I was mislead, I think, I worked with the offset bumping and worked much better, thanks
