Help with maintaining cape physic when importing to blender

[raw plinth]

i’ve imported the SMD and changed the cloth to [cloth] on Radahns cape, all ive done is use sculpt mode to repose where the cape goes around the neck, but whenever i attempt to reimport my game either A. crashes, B. the cape starts flying everywhere out of control. i just want to import the cape to my modded armor not a new model, it’s the same cape no new faces or anything, nothings working 😔

if you can help me out, please do, and if you would prefer to show me over a call (i would prefer that but, any help is needed and wanted 😔)
