Weird Cuts in final OBJ not visible in Edit/Object mode.

Hey guys.

So I’ve made created some text and extruded it. In edit mode/object mode it looks perfectly cut. However when I open the OBJ and look at it under SCULPT mode there are weird cuts not present in edit mode.

Any ideas? Picture attached below:

That’s not weird at all:
The front faces of your text are huge n-gons (= polygons with more than 4 vertices) and - even worse - non-planar n-gons.

For any kind of rendering (e. g. your After Effects screenshot) polygons will get triangulated. This triangulation works rather flawlessly if polygons are triangles (Obviously!) or quads. But with n-gons this process can result in a horrible shading mess, because the renderer does not know how to split up those areas into triangles consistently. But not only rendering is affected, some viewport shading modes can also produce artefacts, as you see in your Sculpt mode screenshot (BTW: sculpting on top of that messy geometry may not be as funny as you think).

If you want to avoid that, you should remodel your text in clean, all-quad geometry.

No need to remodel. You could simply triangulate the mesh. You may most probably stumble across the same wrong triangulations then though. Which can be fixed by rotate edge. When you need quad topology, there is also a tris to quads command. But also here, you may want to flip the one or another edge then. All can be found in edit mode in the edit menu.
