Questions about the fitting room

hi, i am currently working on a project for a virtual fitting room and i am following the tutorial on Youtube. May I know what kind of 3D object/model should i get on to the Unity Project cause i have tried importing FBX model but somehow it is not detecting any bones. i am exporting directly from Marvelous designer and there is bones, i even exported the bones file (JSON). Is there anyway i can translate any of the files with the programs or template? or there is insufficient files i am missing. i even created the bones manually on the project but the model isn’t following the bones when i clicked T-Pose. please enlighten me thank you

Hello @draguava
FBX is usually used, you can find many examples in the package. One of the best is Mannequin. You can also find many models with a good skeleton on Mixamo
