Subject: environment dome with IDL enabled.
Quote - ok, being a total newbie with PP2012, if i make the dome invisible to camera and raytracing but leave the light emitter box ticked, does Firefly still use the dome and its image in IDL calculation?
ie i need the light effect, but want to overlay the render onto a BG of my choosing.
Sounds like you want just a plain old image based light, for that you do not need to use a skydome or similar; it does use a different map-type, though.
As for the IDL/2012, i do not know, but why not try it out? Just disable all other lights, leaving only the skydome on and render it, if you get anything lit, it works :-)

You need to have raytracing enabled for IDL calculation. So set invisible to camera and have the Emit light box ticked. As a texture you can use a texture or material for the environment dome and you can make it grayscale to eliminate color influence
Quote - I don't understand why you should make a skydome invisible to the camera when a skydome should be large enough to include most camera settings. Even BB's envsphere is large enough to use for aerial scenes.
because i have few image maps that suit the skydomes, so i want to use the BG images i do have, and layer the render over .
Not sure if this would work for you, but I found that to get reasonable image resolution on a sky dome, you have to go to focal-spot of 35 or something, which for figures falls a bit short of complimentary.
So, I use a panorama (curved) plane displaying the image I want to use as backdrop, and a skydome for lighting. Not ideal but it works.
