- OptiX Flags
- Native OptiX Curve Primitive
Use OptiX curves API for hair instead of custom implementation.
- Viewport BVH Type
- Dynamic BVH
Objects can be transformed, added and deleted interactively, at the cost of slower renders.
- Static BVH
Object modifications require a complete BVH rebuild which reduces interactivity but renders faster.
