I am having trouble on a UVW map for a sword handle of a model someone sent me to unwrap and texture. The handle bars are apparently inverted according to UVW Unwrap editor. I tried flipping the faces and mirroring the faces, but I cannot get the faces to stop being selected when I choose “Select Inverted Faces”. Any advice on how to solve this? Am I even explaining the problem clearly? Sorry, flatten mapping usually works for me…

I’m not sure if I understand what’s happening. Could post a sample scene or screen grab?

Let’s see if I can clear this up. I have a longsword model someone sent me to texture as indicated in the first attachment. I applied th Unwrap UVW modifier to it. I used flatten mapping then recursive packing to place the UVs. I select “select inverted faces” as shown in shot two. As you can see, several faces are allegedly inverted. I try to click “flip horizontal”, nothing happens. Picture three shows the faces still being marked as inverted… Now they are both inverted and overlapping as seen in picture 3.

This may sound like a stupid question, but I’m going to ask anyway because I don’t want to assume. Did you try deselecting after you chose “Flip Horizontal?” Are you not able to select other UVs after that?

Yes, I did, heh. I then once again try to select inverted faces and still get the same areas as being inverted…

Okay, I can’t think of other things. Did you check to see if the model itself isn’t a problem?

It it’s not too much trouble, could you zip and post a scene with just one inverted poly and not the whole sword? Delete the rest of the model and the Unwrap modifier. Obvious reason being that you may not want to post it publicly.

Here’s the scene with just the troublesome handle. I haven’t been able to figure out if it’s the model or not…

Several points.

1) Because of all the missing images that scene took AGES to even open - I ended up having to remove all the maps except the Diffuse ones, and replace those with Checker maps, just to make Max usable.

2) The model itself. Well, low-poly is good, but removing all the longitudinal edges? I’m not certain if that’s a good idea. It’s not something I would do - maybe someone else can chip in here and clarify. (the attached blue image).

3) The UVW mapping does look wrong. The two “halves” (upper/lower) aren’t the same - they overlap the applied image. This is easy to see with the checker map. Re-apply an UnwrapUVW and you can see what I mean. Bear in mind that I didn’t change any settings in the materials, just the images they used.

Sorry about the trouble with the file. I didn’t even think about the texture maps. I don’t even know how to clear material slots…

That was the culprit. The object is cylindrical with curved surface but has no longitudinal edges. Unwrap doesn’t seem to like it, and rightly so. This makes operations like Flatten difficult.

See my attached pics. Hope this helps.

Well that helps explain it. Appears my opitmizations backfired… I’ll try to fix this later. Thank you.
