To solve the long-time challenge of rendering scenes with many lights, Chaos Group's R&D team has written a new Adaptive Lights algorithm that drastically speeds up render times. After extensive testing on architectural interiors and large environments with hundreds or even thousands of lights, benchmarking results show that Adaptive Lights can be up to seven times faster, depending on the scene. Now artists can work with a virtually unlimited amount of light sources, rendering scenes that were previously impossible.
“We’ve been testing V-Ray’s new Adaptive Lights on the GPU, and we’re impressed by the results,” said Tomasz Wyszo?mirski, studio director at Dabarti. “In one of our scenes, render times were seven times faster than before – a 54 minute render dropped to 7.5 minutes with Adaptive Lights! The difference is amazing.”
Other Top Features Include:
Interactive production rendering – Fully interactive production rendering with immediate feedback.
Glossy fresnel – New, physically-accurate reflection model adds more realism to any scene.
Resumable rendering – Ability to stop and continue rendering at any point, preserving work and saving time. Supports both progressive and bucket rendering.
Live VR rendering – Render directly to Oculus Rift or HTC Vive with full GPU acceleration. Visualize changes within the headset as they are made in 3ds Max.
V-Ray Scene node – Import and render complete scene files created in any V-Ray application. V-Ray scenes are render-ready assets and contain all geometry, lights, materials and textures.
Interactive lens effects – GPU-accelerated glare and bloom effects that can be enabled and adjusted while rendering. Compatible with V-Ray Denoiser.
alSurface material – General-purpose shader by Anders Langlands includes built-in SSS controls; popular for skin.
MDL materials – NVIDIA’s universal material format is now supported by V-Ray, allowing designers to apply MDL materials authored in programs like Substance Designer to their assets and scenes.
GPU Rendering Improvements:
Continued V-Ray GPU development has led to faster speeds and an expanded feature set. In addition to the speed gains of Adaptive Lights, memory-efficiency has been dramatically improved through On-Demand Mip-mapping; an intelligent way to load and render textures quickly using automatic processing and the GPU.
V-Ray GPU will also now support:
iToo Software Forest Color textures
Cached irradiance maps
Directional area lights
Low GPU thread priority
