I am loving the new caustics, but it would be even better if we could toggle the effect on/off in VFB, in the same manner as Bloom&Glare.
Currently I find it more practical to set caustics to render only in element because it can often produce splotches/fireflys that need a lot longer to resolve. This means then opening in photoshop to add the caustics, which is yet another step.
In addition, being able to adjust it in the LightMix panel along with other light sources would make sense.
Hope that's all clear.
