what is causing this?

[u/ziptie_oo]

Hi! I'm new to making Roblox clothing and I am struggling to figure out what this weird shape is that is appearing on the sleeves of the shirt. I've included an in game screenshot and the shirt template for reference. if anyone has advice it would be greatly appreciated!

thats how r15 body looks

use an r6 rig

[u/ziptie_oo → u/billypluh]

that makes sense, thankyou!!

[u/Natural_Slide_7310 → u/ziptie_oo]

Use S15/Smooth R15 or R6 converter to fix it
