The progressive image sampler makes rendering spontaneous. Change lights and materials in real time and get immediate feedback – even with complex features like depth of field, motion blur, and volumetric effects. With no waiting for test renders, you'll have more time to be creative.
The progressive image sampler supports V-Ray's complete feature set – including its powerful global illumination options – brute force, light cache, and irradiance map.
