How do I mirror a Material

Four panels with a marble texture. I’d like to mirror the initial texture of panel 1 on to panel 2, then mirror 1& 2 on to 3 & 4. Mirroring the surface does not mirror the material.

Hello - if the surfaces are single surfaces and the material is applied as surface mapped to channel 1, then using Dir to modify the U and V of the surfaces should remap the material. But if the texture is using WCS mapping that will not help, you’ll need to set the texture to a size that repeats once and mirrors:

Post your objects if that does not help sort it.
