Caustics

[flipbook]

Sorry I know this isn’t directly Phoenix but it is while I am using Phoenix for shoreline setup!

I haven’t really used caustics and I just put a vraySun in the scene, enabled caustics and get a very limited area affected as you can see below, which I really like. Is there a way to extend this when using a vraysun?

I tried switching to a standard light and increasing the hotspot size but looks no where near as good.

Any help appreciated!

there is a parameter “photon emit radius”

Got it working on standard lights but doesn’t work with vray sun… shall take it over to the vray forum

Hey flipbook.

Works perfectly on my side, the photo emit radius setting is just underneath the shadow bias setting in the vraysun parameters.
You should see it change the size of the vraysun “cone” in the viewport.

Ah thanks, that’s where the setting is… totally overlooked.. thanks!
