This is my first experience with developing low-poly character model. I was amazed with the amount of details can be transferred by the normal map. I created the base concept in zbrush using dynamesh. Then developed the high-poly mesh on the surface in blender. after this step, I started making the low poly version. after unwrapping and packing the UVs, I baked the high-poly surface information on the low poly using substance painter. I also created textures inside substance and I enjoyed it a lot.
There are about 10.6K polys (20.7k tris). I generated 6 UV sets for the whole character. Each contains: Base color, metallic, roughness and Normal.
I love to learn more about this technique in next projects. For now I would like to rig this guy and make some short animations. Can't wait to see him fly.
