Uppercut shows how to get fine detail from displacements while keeping render speeds high.
The Uppercut team posts a look at working with displacements in U-Render for Cinema 4D — the high-quality real-time rendering engine for design, and visualizations. U-Render has physically based materials that support subdivision surfaces which in turn can support highly detailed displacement mapping.
The question then becomes how do you keep the rendering speeds while preserving that detail? Watch the tutorial that answers this and shows how to quickly set up materials to use displacement map textures to add fine detail to your models and how to keep rendering real-time by using dynamic geometry subdivision.
