Ok cool, seems to be working.. Now I just have to figure out these missing faces in the stomach, but I have a feeling that's my bad geometry, and not optimizing my mesh yet

UPDATE PROGRESS! : Okay so based on the information you guys reported. I realized , it was the way I was importing the Male_2016_08_05 Into Blender to begin with that was causing the problems. And then All I have to do is export as a regular old dae and things seem to be working fine.. Hopefully everything from here on out will be smooth sailing, fingers crossed.

Thanks so much both of you. Very helpful.

Modified mesh, tried different weight paints, tried different topology.

Basically this is the Male_2016_08_05.dae reference file given in the documentation for second life If I upload the file I directly downloaded it doesn't have these deform issues. https://wiki.secondlife.com/wiki/Project_Bento_Resources_and_Information (collada human male) However when Import that file into blender, then export it sl+opensim rigged dae.. I get all these strange deformations when uploading to SL. I'm sure this is a simple fix and I need to tick a box somewhere, but I'm stumped. Any Ideas?
