Re: Test for Inverted UV's
Yeah, just showing seams (boundaries) should be enough to spot them, select them, and dispatch them.

Re: Test for Inverted UV's
Only one UV polyface in an island has been inverted/flipped ? If that's the case you should be able to detect it in your Tex.Editor. Softimage doesn't "merge" UV samples that aren't adjacent so their borders should appear green/blue in the Text.Editor when you select them because they are not "merged". If the samples are adjacents and have the same coordinates, then they shouldn't have green/blue borders.

Re: Test for Inverted UV's
sorry guys, wrote that quickly k so apparently these artists have somehow managed to create UVS where some of the polygons in that UV island/shell/hull are facing in the opposite direction. So that on those polygons the bump and displacement maps are inverted. I'm not sure how they actually did this, they probably cut up the uv's and then tried to put them back together, but somehow messed it up, and now some of the UV's are flipped. They are new starters from a company that used 3dsmax so they are still getting used to the xsi workflow. They have asked us if there's a quick way to tell if a UV is facing in the wrong direction. Apparently in 3dsmax the uv's would be a different color in the uv editor. anyway i dont think that there is, as I've never ran into this issue before, when I UV i just a combination of projections and uv unwrap. and everything comes out okay On Sun, May 12, 2013 at 8:57 AM, Raffaele Fragapane < raffsxsil...@googlemail.com> wrote: > Was about to ask for the same.

Was about to ask for the same.
