Ray Tracing Acceleration
Fast Preprocessing
When in use, it allows Redshift to update scenes more quickly by aggressively optimizing/limiting what is processed from the scene before starting a render. This is ideal for maintaining high interactivity during Interactive Rendering but it comes at the expense of some ray tracing performance.
- None - Never use Fast Preprocessing.
- IPR Only (default) - Only use Fast Preprocessing during Interactive Rendering.
- All - Always use Fast Preprocessing for both Interactive and Final Rendering.
By default Redshift only uses Fast Preprocessing during IPR rendering to ensure that everything is appropriately updated during Final Renders.
If you notice differences between interactive rendering and final renders try setting Fast Preprocessing to None to see if that fixes the inconsistencies at the expense of responsiveness during Interactive Rendering.
