IK rig's arms are moving incorrectly when imported into roblox


I imported a spear thrust animation from blender but as you can see in the roblox studio clip the arms are not correct

my export settings:


i have tried importing the same animation into blender and the arms are correct, so it must be a problem with roblox

Umm… I don’t know uhh try maybe

i had a slither of hope there thinking that would fix it but it turned out the same, also i should remind you that when importing the exported fbx file back into blender it works perfectly fine, which is what made me assume this might be roblox’s problem instead of blender’s

Ok so it could also be an export problem, right? What if you change your export scale to 0.01.

i already did that and unfortunately results are the same

do you think it could have something to do with the arm’s origin position?

thats what i thought too but i checked and they seem normal

I don’t know much about animating in Blender, but what if you removed the IK, but still kept the animation?

to remove the ik is basically removing the animation so yeah i cant do that
