    Question about morphing an imported OBJ file.

    I've recently working on Poser Pro's different characters in Lightwave. One of them comes with its own UV map if exported in OBJ format. But I want to morph parts of the face to resemble an actress. If I do that - without adding new geometry - will it invalidate the UV map it came with, thus required a new one be made?

    Hi, should work fine.

    Pretty sure he meant .lwo.

    Test out setting the options for Obj's in the General Options panel BEFORE importing the object. Sometimes I want separate layers & sometimes I don't for example. There's no reset to Default so not really sure what that is. Guess it's whatever worked best last.

    Thanks for the advice. Poser's latest character, La Femme, appears to already set its UV Map in UDIM order if I import it as an OBJ. But older ones just seem to bunch them up and overlap in one single grid. I'm not sure if I want to use older character meshes like that. But just in case, can Matt Gorner's Fit UV's plug-in help me fix that mess?

    not sure, it might.
    u could also try doing it manually.

    Haven't had any need for awhile now, but I generally had better luck opening Poser assets from within Daz first then export to obj or fbx. Might give that a try.

    If it could make sense out of this I'd like to give it a try. Or else I can carefully try cutting and pasting the parts into a new UDIM. Might be good practice to make a new one from scratch.

    Mein Gott! I don't know if it's the file or not. Using UV Overlap to move the islands around freezes the program.

    yes, i general, cleaning up geometry or UVs can take quite some time.

    I think it worked. It's separated the UVs into different maps. So I guess I can move those around a new UDIM. Some of them are just badly made, like the eyeballs. LW also crashed trying to deal with the mesh's original texture images. It's no biggie because I'd prefer to make new ones. Let it be a warning for anyone using old Poser characters.
