Tennis ball model

Create cube - modifier - parametric deformer - spherify - select edges - chamfer twice to add geometry- turbo smooth - then with all the edge lines selects hold control and select faces - extude inwards slightly - spherify again and increase iterations to smooth out.

I tried to add textures but had problems making the distinction between areas of the ball and could only get a block colour, this is where UV mapping would come in handy.

These are the final rendered images of the tenis ball with no texture applied

I also inserted a omni light to produce shadow in the scene.
