Clothes stretching: Why is this happening!?

I converted this shirt to fbx in blender, then attached it to my character in Daz. Made everything fit properly, but it clips & stretches during animation and posing.

    You need to rig the shirt with the transfer utility to give it bones and weight mapping, and then "fit to" the character.

    Yeah, I came across this solution a few hours ago. It helped a bit, but there's still some stretching that occurs when the arms are raised above the head.

    Thanks for replying. I just wish this site didn't take hours to actually post the topics after the user has created it! It would help workflow move much faster!

  • The Transfer utility is unlikely to give perfect results, especially when - as here - the cloth is far from the skin. The lower portions of the upper sleeves may well be closer to the torso than to the arms, and so will receive weights from the torso rather than the arms. The node Weightmap brush will enable you to improve this, but you are likely to also need custom corrective body morphs thata re linked to certain bends to get the best results possible.

    Sometimes it helps to have a more tightly fitted 'version' of the mesh to use in Transfer Utility so weight maps are applied more accurately, and then have the loose version as final shape after weights applied.  Transfer Utility applies weights from the figure using assumptions based on distance/proximity, so the more closely the clothing resembles the base figure the better the rigging transfer might be.

    There are some tutorials on youtube by sickleyield about using transfer utility, then weight painting to smooth out issues, and then using Joint Control Morphs (now called Corrective Blend Shapes) to fix persistent issues.

    Mada also has excellent video tutorials. Creating clothing that works well in Daz Studio can be a long complicated process. https://www.youtube.com/@MadadeLeeuw/videos
     

  • After 4 days of trying; I give up!! Unless someone here can convert it to a working Daz format for G8F? I can upload the shirt as obj file.

    If the shirt is welded, you can try to use add dForce to it and simulate.

    Where do you have the shirt from?

    In addition to rigging (1st step with Transfer Utility), you may have to further fix a couple of things on the garment - FBM, pJCMs at least. Even if you go for setting up dForce, some techniques are necessarily required on this "thick garment" with such a design (e.g. keep the shape of sleeves, back piece... when simulation, etc. ...)

    If the shirt was made by yourself, you can upload.
