I fully agree with Orion. A Meta('bracket') with some faces should work and it's quite simple.
We just need to distinguish between the surface types. For example:
Type1 -> Standard (smooth) -> no Meta is needed
Type2 -> Slope (low perforation) -> Meta 'SLOPE TEXTURE_LOW"
Type3 -> Slope (high perforation) -> Meta 'SLOPE TEXTURE_HIGH"
I'm sure there are better combinations to describe these things.
