either im missing some step somewhere, or the per-object caustics multiplier is broken?
attached image shows 6 spheres, 3 materials.. first refractive, second glossy refractive with fog and interpolation, third with hybrid translucency.
back row has caustics multiplier of 1
front row has caustics multiplier of 5
no visible difference i can see.
also, out of interest why do the caustics look much smoother from the hybrid translucent one than the glossy refractive one?
ok so i tried a caustics multiplier of 50,000 on the front row… result attached. strange it effects the front spheres, and to a small extent the back row (which still have a multiplier of 1.0) but no affect on the floor.
looks like its behaving as a recieve multiplier not a send multiplier.. (apart from the splotches on the rear spheres) but the spot 3d manual states:
Caustics multiplier - this value is a multiplier for the caustics generated by the selected object(s). Note that this value has no effect unless Generate caustics is checked.
The multiplier is for received caustics, not for generated ones. I corrected the spot3d page - sorry for the confusion.

thanks for the reply.. since my requirement was to increase the caustic effect coming through the glossy and sss materials, is a “generate caustics” multiplier actually possible? or alternatively, another slot in the “override material” for a caustic material?
It might be possible and I’ll make a note to add a “generate caustics” multiplier, but for the moment you can create a separate brighter light just to generate caustics for these objects.
Best regards,
