Why does my mesh have lots of square on it? I made a render animation but the mesh seems to be too bright and it seems too square if you understand. Well, I'll add a screenshot, and I want to know what can I do to make it look better.
First, select the mesh. Then click on the Tools Tab, and under Shading click Smooth.  Another option would be to subdivide the mesh.

Edit:
Also, if you don't want the bright spots, go to Properties > Material and change the Specular Intensity to zero.
