I Modeled a Quick Test map for my up-coming game but when i Imported it, It had these holes or gaps in the map which where not on the blender model
This is what it was supposed to look like
And this is what it looks like
Hard to tell from the image but it may be an issue of needing to recalculate the outside of the mesh’s faces. You can check if normals are flipped if enabling “DoubleSided” in the mesh’s properties in Roblox fixes the issue. Mesh>Normals>Recalculate Outside in blender to fix
If the previous comment doesn’t fix the problem, you might have n-gons. triangulate the faces.
hole in places = faces that couldn’t be imported
fix = find the holes in blender that u see in studio and then just select the face and press ctrl+t in order to triangulate it
