Why is my Mesh inverted?

[creepersaur (creeper)]

So, I imported a gun OBJ file that I made and it was supposed to look like this:

but when I uploaded in roblox it inverted the mesh and its really weird, is there a fix?

I think I got a fix but I don’t know if it works yet because my whole mesh is the opposite of what its supposed to be…

If your model has missing parts it’s because your faces are inverted. The face’s normals are inverted (inside out). You’ll need to flip your normals in edit mode select the inverted faces or mesh and flip it. If your wanting a different approach if your using the later version Blender 2.8 try looking in the upper-left corner of the 3D view menu and click. Mesh > Normals > Flip Normals.

As in the future there has been similar threads regarding this issue consider researching the problem your having first before attempting to create new threads just to see if your question hasn’t been asked before:

Transparent meshpart when imported into roblox problem

Basically, as @RegularRival said, your object’s Normals (the faces) are inside out. If you’re using Blender 2.79 (or earlier), Ctrl + N “Makes Normals Consistent” inside: [image] If your meshes faces are already inside, it’ll flip them all to the outside. However if you’re using Blender 2.8 or later (which honestly, you should be since it’s better to use and learn on), Ctrl + N starts a new save file, so the solution is to go into Mesh > Normals, > Flip Normals [image]
