Is there a way to make dummy invisible but still shown the shirt or pants?
Make every part of the dummy transparent, except the torso and legs
Is there any way to transparent the arm but still showing the shirt arm side
Unless you use layered clothing, no.
i think you could upload each side of shirt as a decal and put it over a the dummy just like roblox system wraps around since decals don’t go invisible with the part if its invisible. there’s probably another way that im not aware of
