Hello,
after not posting here for a while, I'm back with an announcement of my upcoming plugin:
A modular, layer-based terrain generator for Cinema 4D
Build your terrain step by step from any number of operator objects. Each operator either adds features to the terrain (like hills, mountains, valleys, rivers, et cetera), or changes the existing terrain (e.g. terraces, glaciate, canyonize, folding, et cetera). Operators can be blended with each other using one of several blend modes, just like in your favourite image processing app. Masking is possible, too, using either Cinema 4D's Fields, or the terrain's own altitude and slope levels.
The operator shader helps creating a nice material for the terrain, by rendering altitude, slope, or Fields mask of any operator object.
Terraform4D focusses on workflow and art directability.
Terraform4D will be available soon for R20 - R23 on macOS and Windows.
Here are some example renderings
(Big thanks to my diligent beta testers!)
