Scattered lights with vRay distributed rendering not working
« on: August 13, 2021, 06:26:07 PM »
I can't get the scattered light along a path in Forest Pro to work with Vray distributed rendering.  Only the local machine renders it correctly.
Is this also a limitation or am I just doing it wrong?  It doesn't work with any lights, vray, standard, ies, mesh.  Anyone else experience this?

I'm afraid it's a limitation of the method we're using to scatter lights in V-Ray.
Currently this renderer doesn't support light instancing (but ChaosGroup is working on that), and we use a workaround which doesn't work in all cases.

As soon as ChaosGroup implement light instancing, we'll make the changes in Forest to support it.

Thank you for the information. I thought as much. My renders keep ending up with mis-lighted buckets every time I turned on the Forest objects with vraylights in them. Do you have any idea when we can expect this to be functional?

No idea, sorry. I know ChaosGroup was working on light instancing (ticket VMAX-8645), but we have not more information.

We created a post in their forum about this:
