I’ve done my caves by using template brushes and copying and pasting.
Each brush is caulk apart from one face (the inside) which has a phong rock shader.
Trouble is, because I copied and pasted, each brush has texture coordinates that don’t line up.
If I was only doing a few brushes, I’d select all the rock faces manually and simply set them to have the rock texture - thereby making them all go back to default box mapping, and so they’d phong / be seamless as much as possible.
However, I’m not talking about a few brushes, but hundreds possibly thousands.
Selecting each by hand sounds like a nightmare to me, so I was wondering if anyone knew of a quicker way of taking a bunch of brushes, and selecting all faces that use only a specific shader, or resetting each face to use default mapping of whatever shading it’s got (don’t mind if the other faces change UVs, they are only caulk after all).
