fom my post on the lamrug site:
I’m trying to understand if I can apply a different texture to faces created with a displacement map. Consider this basic eaxmple:
In the scene there exists a square poly plane with 3x3 subdivisions for 9 total faces which has been textured with a numbered grid with a number that correspondes to each face 1-9… If I displace the center face (# 5) 1 unit, is there a way to map different textures to the new tangent faces connected between (2,5), (4,5), (5,6), and (5,8).
Perhaps a brief explanation of what is actualy happening in terms of geometry paramaterization and uv mapping during displacemet, inside mr would shed some light…
