Taj Mahal model for MCAP 2 (Massive Collaborative Animation Projects). Images above were rendered in Marmoset Toolbag 3. However, the final animation for show at the Michigan Creative Expo was rendered in UE4 (last image).

The pieces were modeled and unwrapped in Blender, some of the UVs were manually packed, some were packed with Houdini's UV Layout. I used support loops to get smooth edges instead of baking from a high poly.
They were then sent to Substance Painter for texturing. The stone/ brick smart material was created in Substance Painter. The normal details on the inner walls were stamped on using alphas created in Affinity Designer. Some of the patterns were also created in Affinity Designer, some were provided by my teammates.
This took about 70 hours across 3 weeks to model and texture.
