trying to makethe moldy crow from star wars dark forces.everything works fine till i add thewindows. up till i make those cuts it willsubdivide just fine. trying to subdivide for a texture displacement

Blender can not subdivide n’gon’s normally, its coz it doesn’t know how to shape the new created faces
you either have to make then quads
triangulate them and then subdiv
or, subdiv them yourself using the cut tool in blender

si a tri face will subdivide?
