My mesh didn't came out correctly

I was working on my new kart, and as I import the main body part of the car… I suddenly spot some missing gaps.

This is what it should look like (Blender)



(There are no gaps on the mesh I was making)

When I imported an FBX file to ROBLOX


As you can see, there are 3 gaps that are missing on the front part of a vehicle.

Is there a way how to fix this?

Have you tried exporting it and then importing it again?

Some of your Faces are flipped, try finding those faces in Blender and do Shift-N or delete those faces and fill it in. Another method is flipping those faces by doing this:

I looked under the gap that’s missing, it’s nothing.

So, when I got back to Blender…I realize that the edges were in the wrong pattern - so I decided to re-form this:

Try finding those gaps in Blender and fill them in, with that turn on Backface Culling to find them and correct them.

Now it doesn’t have gaps at all.

You may want to triangulate all faces to make sure no face is getting wrong calculations, faces with more than 4 vertices sometimes tend to go a bit weird I think.

A quick solution for gaps is using backculling, I then select every face, and then re-calculate the outside. I think this can be found under “mesh”, then look for “normals” and select “re-calculate outside” if I’m correct.

Not super experienced with Blender but since I’ve ran into this issue as well I also had to find solutions and this one fixed all of my problems.

Edit: Corrected it.

Awesome fix! I don’t often run into these problems mostly because i am always on the look for wrong Faces/Doubles. But when i do i know its a easy fix.
