Caustics - Bug, feature request (or is my brain offline..?)

Caustics - Bug, feature request (or is my brain offline..?)

Hi,

I am rendering caustics and want only the caustics with a corresponding
alpha. When I plug in the Photon_Irradience on my reciever object I get
the message "No photons stored after...".
After some headscratching I found a work around: First generating a
photon map with say Lambert on the reciever obj, then rendering again
with Rebuild off and Photon_Irradiance. Then everything works as I
expect. But this doesnt really work if the transmitter object is
animated, which I need in the end.

Am I missing something obvious here? As far as I remember the
Photon_Irradiance works well with FG.

Cheers and good weekend,
Axel
