When trying to import certain items into blender for GFX purposes, the texture does not show how it is supposed to. I have tried re exporting and importing, but I get the same result.
I think these cartoony accessories use something called an inverted normal which can make cartoony outlines in someway. Here’s an example which makes an outline over your head
And I think that may be messing it up.
Or maybe cartoon outlines look like that in blender. You should try importing the item into blender, and not edit it, and save it and put it back into Roblox Studio to be sure that is the case.
You should go to 14:00 in this and do what she did to make the mesh into a cartoony outline
It won’t show in blender but it will show when you import it into Roblox. Or maybe when you render an image, I don’t know, cause I don’t have blender installed lol.
