Operators can be restricted to certain areas of the terrain by masking.
Terraform4D offers different ways of creating masks:
One way of masking is to restrict operators based on the terrain’s topology. That’s very easy with Terraform4D’s topological masking.
Mask areas according to altitude…
…or slope angle. This gives you rocky cliffs, and sandy plains.
Additionally to masking operators according to topology, you can harvest the powers of Cinema 4D Fields to constrain operator influence on a local basis.
Use the whole palette of Fields to mask your operators.
Manage Fields comfortably in the Fields list, and use them to combine operators precisely as you want.
You can even animate your Fields….
…or program your own.
