Question for the folks in the know..

I've modeled a figure in XSI, and the arm and leg pieces were duplicated using the symmetry feature. They are exact copies and share the same topology; they are just mirrored over the Y axis. When I try to run find similar or same, UVLayout does not recognize the other arm, leg, etc.

I also tried the same technique using four barrels from a weapon on the same model, and find similar worked fine for those elements that were created the same way. Any suggestions would be very helpful since I want to save UV space by stacking these UV's and it's a bit unwieldy unwrapping them and getting them proportioned exactly using manuel methods.

Thanks.

The Copy UVs find matching tool only works on separated objects. Is that what you were trying to use?

For a connected mirrored surface like a body, use the Find Symmetry tool when you first load the objects, then all editing and flattening on one side is applied to the mirrored side. If the Find Symmetry isn't picking up the mirrored topology, then it should be highlighting the problem polygons. Sometimes OBJ export plugins will turn polys with 5 or more sides into quads and triangles, which will break the symmetrical topology.

Thanks for responding Phil.

To provide more detail, I tried copying the UV's both with an obj that had connected geometry (i.e. mirrored over in my modeling program using the symmatrize function) which didn't work. I went back to my base model and tried again using dupilcate and instanciate to ensure each piece was considered it's own and not linked to the original geometry. Again, no luck. As I said, taking the same steps with cylinder based geometry didn't have a problem.

As far as N-gon's, prior to exporting into UVLayout I fixed the few that existed, so I know that I'm n-gon free. At next opportunity, I'll try to get the find symmetry function and see if I can get matching UV's this way, and hopefully stack the result.

Any other insight or workflow suggestions would be helpful, and if you think posting screens would help, I'd be happy to do that as well.

Thanks again.

Can you email me the OBJ? That's probably better than pics because I'll be able to find exactly where the problem is.

Thanks again for looking at this Phil. I emailed the obj to the email listed in the contact info. I was able to get UV's copied as I state in the email, but without the find same/similiar feature. So progress, but being a stickler for getting things to work without work arounds, I'd still appreciate any insight.

I'm sure it's user error and I want to nip it in the bud so I can be more effective going forward.

Thanks for sending the file. Actually, it looks like a bug ... the match should be working across your mirrored pieces of geo, but aren't! I'll try to have a look at this next week.

I'm having a similar problem with a piece of geometry. Has the bug for this been fixed ?

[headus]

Sorry, forgot about this one, so bug not fixed yet. If you email me your geometry too, I can check it too.
