hello!
My bad, i didn't thought that always_sample would be taken into account inside a
radiosity block under a if block evaluated to false, but still it was my mistake
to not have tried first to change the value.

so yes, it works now thanks to you.

i will perform a little ritual with an offering to the POV-Ray Gods to calm
their wrath :)

thanks !
