Mirror doesn't seem to be doing anything for me... might be missing something.

The mirror effect can only be observed in Maxwell FIRE (or Render), and in the texture editor's preview, not in the Rhino viewport, if that's possibly what you're referring to. And of course, it would have no effect if the texture in question happened to be symmetrical.

[Wynott]

understood... it's not doing anything in fire or in the texture editor preview. No change in material editor preview either.

[JDHill]

In that case, I'd assume the texture is not being tiled (that is, Repeat is set to 1.0/1.0). Mirroring means that each tile alternates its mapping, such that the right edge lines up with the left edge when mirrored along the X axis, and so forth. This can only take place within the context of UV space, so there would be no effect if you were to leave Repeat at 1.0/1.0 and change tile size by actually mapping a different size UV space onto the object.

[Wynott]

Ah ok understood.

So... I've got some flags flying upside down. Expectation was that enabling mirror Y would flip them around.

[JDHill]

Yes, mirror's just for helping non-tileable textures tile a bit better. To reverse texture direction, try setting Y Repeat to -1.0.

OK thanks Jeremy.
