Redshift Renderer for Cinema 4D

Redshift is a popular GPU-accelerated renderer integrated with Cinema 4D, designed to offer fast, high-quality rendering for complex 3D scenes. By enabling OptiX (NVIDIA’s real-time ray tracing engine) in Redshift’s experimental build, users can significantly reduce render times and improve workflow efficiency.

How to Enable OptiX (RT/AI) in Redshift for Cinema 4D

1. Launch Cinema 4D
   Open the application from the default location:
   C:\Program Files\Maxon Cinema 4D R##\Cinema 4D.exe

2. Activate Redshift Renderer

   • Go to Render Settings and select Redshift from the Render Using dropdown.

     

   • In the Redshift UI, navigate to the System tab.

     

3. Enable OptiX RT

   • Scroll down to find Experimental Features.

     

   • Check the box next to Enable OptiX RT to activate NVIDIA’s OptiX real-time AI-accelerated ray tracing for faster rendering.

Top Tips to Speed Up Redshift Rendering in Cinema 4D

1. Use NVIDIA Studio Drivers
   Installing NVIDIA Studio Drivers ensures maximum stability and performance for creative applications like Cinema 4D. Studio drivers are optimized for 3D rendering, offering enhanced compatibility and better resource management compared to gaming drivers.

2. Adjust Sampling and Ray Depth
   Lower the Ray Depth for reflections and refractions when working with transparent or reflective materials. Reducing these values can cut down on unnecessary calculations without a significant quality loss, especially in scenes where accuracy in reflections is less critical.

3. Optimize Textures
   Redshift’s default texture filtering uses Anisotropic for primary rays and Bilinear for secondary rays. If your scene has textures that don’t require high fidelity, reduce the filtering quality or lower the texture resolution to save GPU memory and speed up rendering.

4. Leverage Hybrid Caching
   If working with large scenes, utilize Redshift’s out-of-core rendering to store textures and geometry outside the GPU memory, freeing up space for faster processing.
