Thanks so much for the response. Hope all is well with you. Your software is amazing !!!

I think I've narrowed down my explosion issues to some rigged fingernails for the G3 character I'm using. I purchased them in the DAZ store years ago. For some reason, if I first remove them from the character before doing a VWD animation simulation it works fine. But with them fitted to the character the explosion always occurs.

Regarding the geograft, I don't even know what that is, so I doubt I applied it to my G3. Unless some morphs I purchased have it...

Anyway, what I usually do is make OBJ files for my clothing in Blender and export them to DAZ and VWD to perform simulations. And generally the simulations work fine. I've figured out the correct mesh density and how to make the mesh uniform in Blender, so I usually get some great simulations.

Thanks for the help !
