Severe UVW Map Error (Can anyone help)

Volkov

Okay I got this model sent to me via gmax format, and I exported it to W3D, and imported it into 3D Studio Max using a W3D Importer, whenever I attempt to use texporter on the model, the unwrap does this, does anyone know what the error is?



I have got absolutely no idea in the slightest, it seems to only happen with unwraps where I weld the vertices together (on the UVW map). But in this circumstances the unwrap was done by someone else, and the vertices where already welded.

It was perfect when I freshly imported it, the UVW map had no such errors, it was only when I moved a few polygons that this began to happen.

Dunno. I'd import the model again, immediately save a .UVW file, then go on from there. You can always re-load the UVs if you need to, as long as the vertex count hasn't changed. You could even use the model you changed as a morph target for the new one, to restore your changes. Are you in Max 7? There's that new UV projection tool.

Volkov

Yeah I'm using Max 7, what new UVW projection tool? I thought it was Texporter and that's it.

Eric Chadwick

Texporter is only for creating a bitmap our of your UVs. There are other ways to do this, one way is PSDPathUnwrapper.

But for what I was talking about, look in your Help file under What's New... New Material/Mapping Features... Projection Modifier. Pretty cool stuff.

This sounds like the culprit to me, whatever you did here may have caused the error. Perhaps you had some uv's hidden, and moved some around not realizing they were welded?

I would retrace your steps with a fresh import and slowly figure out where this happened.

Actually projection modifier will not work on UV's. That's one of the only things it does not work on, and this came from the discreet rep himself. Several people at mythic have tried to figure a way to do it without success. Supposedly that is coming though.

Did you turn any edges?

I’ve seen this occur when the mesh has been modified at the edge of the UV map. Most times when an edge is turned that cross sections another portion of the UV. You can see that the verts are snapped from one section too another. Not much of a problem all you need to do is break the verts and move it back into the proper position.

Volkov

I figured out what caused the errors, this only started to happen when I welded vertices together too early, I just wait until I have all the polygons sorted inside the map, then I weld them together, thus eliminating that bug.

But I can definitely say without a doubt, that it wasn't a stray vertice, if it was one of the polygons would show distortion (I always apply a checker flag temp skin).
