Hi kcbale I've fixed the problem implementing a simple setLightColor with no stateSet dirty: i've updated the uniform value only. This work.
Right now, I look around another issue on the last ocean revision (258). Your ideas are really appreciated: http://forum.openscenegraph.org/viewtopic.php?t=12313 many thanks again bye! kcbale wrote: > Hey Dario, > > Ah Ok i understand.
