V-Ray 7 GPU Caustics: Faster, More Realistic Light

V-Ray 7 brings GPU caustics to the spotlight, turning tricky light behavior into a fast, reliable feature. Glass, water, and shiny metals now cast those sharp, dancing light patterns with far less waiting and far less guesswork.

Instead of pushing all the math through the CPU, the GPU traces and gathers light paths in parallel, then resolves clean caustic highlights with less noise. That means fewer workarounds, fewer extra lights, and more accurate results straight from the renderer.

In product shots, pools, and interiors with glass, scenes converge faster and look closer to real life, even under tight deadlines. For a helpful walkthrough on related workflows, see my previous article on how optimization helps to automate repetitive tasks .
