I just recently finished designing my roblox UGC hat accessory. I exported the blender file to roblox and it is disfigured. I have been searching everywhere but cannot seem to find a solution.
I am not sure why this happened and why the middle part of this cap is missing.
If that doesn’t fix it, you’ll probably have to remake that face on the model. Try splitting it into as good amount of segments, and make them approximately shaped like a triangle or rectangle.
You’ll want your meshes edges/verticies/wahtever to look something like this:
For anyone searching for this themselves… red is the opposite of what color the faces should be! The outside should be blue and the inside red with face orientation on.
