Polygon Pen covers all the new modeling features for R26.

The latest release for C4D offers some modeling additions bringing the modeling environment closer to par with other DCCs.

Likely the most exciting feature comes from the acquisition of Pixologic, bringing zRemesher into Cinema 4D natively. 

Polygon Pen covers working with zRemesher in C4D and looking into Fit Circle, Bridge, etc., and works the features into his hard-surface modeling style.
