I’m using the new Unity alembic importer. The fbx import settings have a handy normal mapping feature that allow you to import, calculate or have none. None is what I need here but the alembic settings are quite restrictive.
The mesh in Unity looks identical to the mesh after reimport in C4d. One thing I noticed though is that I can click on the mesh in Unity and see the low poly wireframe, something that isn’t visible in c4d weirdly, it’s like the phong normal is baked onto the object even though I have everything deselected on export.
I’m thinking some special shader to force reject normals would be the work around, but I’ve no idea where to look for that.
