There is also V-Ray Light Baking to bake V-Ray lights directly into Unreal with GPU acceleration. Chaos Group states that “unlike other light baking implementations, V-Ray Light Baking maintains V-Ray accuracy, ensuring a lifelike, physically based result for real-time experiences and VR.”
Features:
- The ability to render Unreal scenes with physically accurate, ray-traced lighting.
- The ability to render realistic bounced light using V-Ray’s Brute Force and proprietary Light Cache global illumination algorithms.
- The ability to render sequences from Unreal’s Sequencer to create ray-traced animated cinematics. Deforming objects can also be rendered using V-Ray Proxy objects.
- The ability to use GPU+CPU Rendering CPUs, NVIDIA GPUs, or a combination of both.
- Compatibility with Unreal’s native foliage system for rendering large environments and landscapes. (Support for animated foliage is promised soon)
- Support for V-Ray Proxies.
- The ability to create Render Elements for compositing.
- Distributed Rendering
