Here are the 3D models of the base ships from Lego Star Wars Battles.
Surprisingly an Imperial TIE Fighter doesn't exist as a Lego Microfighter so we had to adapt a First Order TIE Fighter to fit the bill.
No Normal maps allowed so having to rely on beveled edges and face weighted normals to control shading. This method of modeling also allows for a bit more fidelity in the model as we are not using hard edges with split normals.
