I am currently attempting to import a Shield Model from blender. But whenever I do so, I encounter this weird glich and I was wondering if anyone knows the solution. So far, I have tried re-importing it as a obj, and FBX, all to no avail.
It’s hard to tell, but it looks like your mesh has incorrectly facing normals.
Go to the viewport overlay menu (the two circles on the top right) and tick Face Orientation to see which way your normals are facing. You’ll see the sides that are rendered as blue and their unrendered backs as red.
As a quick fix, try doing Shift + N in edit mode to recalculate the selected faces’ normals. Sometimes it doesn’t fully work, and you have to flip all the faces manually.
you could recalculate the normals in blender, but usually what i do is when importing the model into roblox using “Import 3d” I go to the file geometry and select “Invert negative faces”
