My caustics are hard to see/not there. I've increased accuracy and radius, and haven't seen any effect.

Make sure your object's frProperties (right click on viewport > frProperties) has "Generate Caustics" turned on. Similarly on the material. Make sure caustics are enabled on the render dialogue. Check to make sure that your light is emitting fR photons, and increase the number of caustic photons for a better result. If your caustics are still hard to see, increase the send/recieve to a large number (e.g. 50) and test. Decrease until you get a good balance.
