Question I'm not sure if I'm missing something, but I created a basic SplineMeshActor with a simple SplineMeshComponent, set the static mesh to be a cylinder and added it to my scene. I'm referring to triangle indices for the resulting mesh. I’ve already tried to triangulate the entire mesh in Blender, to avoid that UE4 needs to do that conversion, but that didn’t change The StaticMesh support in the FBX import pipeline makes getting meshes from 3D applications into Unreal Engine 4 a simple, painless task. Restarting UE editor or PC I imported it to Blender with the settings you see on the right and it triangulated the mesh.

In genral you are perfectly fine withut triangulating the whole mesh yourself, just check for any non-planar quads and split those so you get to decide which way they'll split, and leave the rest as quads. 1) Unreal Engine does not allow importing alembic with a face that has more than 4 vertices. That and some faceting - clearly polygonal lighting as it were. In Blender the mesh doesn’t have this gap appearing and I’m wondering what’s going wrong if its the mesh itself or the exporting process into an FBX . That is why in a program where I bake it looks ok. In a You might have Normals facing in the right direction, but still get some missing faces in UE. On top of it, the project also requires duplicating it generates a null static mesh actor with the mesh slot unable to be occupied. But my character suffers from lighting artifacts as if it were lit by a toon shader. After quickly trying some settings, turning on the flag for If your normals are facing the wrong direction, then those mesh parts will not be visible from the outside, but from the inside (cause the normals are facing inside).
