I thought I had this licked.

But it appears that the texture orientations aren't persistent between rhino sessions. (Open the same file the next day, textures have oriented differently).
I'm using textures with real scale, and sometimes manipulating their (the texture) orientation using the Maxwell Object Properties -> Real Scale Texture Control. Trouble is, after saving the rhino file and opening it again later... my custom texture orientations are still the same numbers (the numbers in the Real Scale Texture Control), but the rendered preview in viewport *and* the actual maxwell render show some other orientation. At least the viewport and the render show the same thing

but it's no longer correct.
Using Channel 1 (hyltom's suggestion in this thread) for the textures does seem to have a positive effect. The texture orientation stays the same between Rhino sessions, but of course, does not respond to Real Scale Texture Control (which I assume only operates on channel 0).
I get the sense that Rhino's texture mapping is still kind of beta. Or maybe it does work but doesn't play nice with other applications? (not passing enough clear info to the plugin). Or am I the only person experiencing this? Problem somewhere between chair and keyboard?
