Hi Bill,
You can decrease the “subdivision” setting in the Effects dialog (menu Tools… Viewing Controls… Effects) and also zoom out the view before exporting.

These are discussed in more detail in this previous post:

I hope this helps,

I tested a smallish molecule in MeshLab and I could decrease the number of faces from 699732 (34MB) to 34986 faces (1.7MB) with minor flattening of the sphere.  Is there a way to have chimera generate spheres with fewer faces?
