Hi CG people.
I share 4 balls similar to Teamgeist - low-poly and high-poly:
Low-poly models have baked textures: Ambient Occlusion, Normal Map and Cavity Map.
40K model was created through a subdiv from the 10K model but has a revised solid to avoid surface flattening and was as close to the sphere as possible.The model also has a default texture to which, if you like, you can add your own graphics.
All mentioned textures are in 4K resolution.
10K model has no textures at all but you can use default texture from 40K model :) ...

Greetings to all.
