is it possible to render caustics using path engine
Posted: Sat Nov 03, 2018 6:36 am
I tried with latest blender addon to render a glass bottle with water, hoping to get a beautiful caustics effect.
I thought it is a matter of rendering time, but after a long time of rendering with path engine, I only got a noise free result. the glass bottle itself looks the same with bidi render. But the shadow of the bottle is solid and no caustics. I heard caustics can be rendered in path tracing renderer but takes longer time. is it possible to do it in luxcore render's path engine?
Also I tried rough glass, it has caustics and gives same result with bidi engine after longer rendering time.
I dont know it is a feature or a bug. Anyway, I created an issue on github.
