Skydome and Final Gather??

I am in the process of creating a skydome in Maya and I am using final gather with a light blue environment background color. My sky .tif file is pretty much the same light blue color with some white clouds. I also have an additional directional light to further mimic the sun light.

Here is the issue. The referenced models render a darker shade with the skydome. If I take the skydome out, it renders correctly.

Is there a way to make sure the skydome does not block the final gather, or am I going to have to render the skydome out separately and compose it in Adobe Premiere/After Effects?

Note: I am trying to eliminate Maya Sun and Sky and IBL lighting as options for lighting this scene. I want to recreate daytime light with a directional light, skydome, and final gathering.

Thank you for any suggestions on this...

Not a Maya user, but have you tried setting the skydome not to cast shadows or receive shadows etc. but only visible to renderer/camera. If he is visible to FG rays it will calculate him in the scene making it a bit darker judging by the object and the it's texture. If you remove him from the equation, scene won't be affected

also, thing we have in max, and i do believe maya has this is the option that a light can exclude an object - set your directional light to exclude the skydome and try then

sorry if none of this helps, just giving advise from a max perspective.

What you could do is just render it on a separate layer.... or go into the render stats of the skydome and turn off visible in final gather, also turn off cast/receive shadows on the dome. That should do the trick

Thanks for the trick...ha. No seriously, I am thinking about just compositing my sky in after effects.

can you not just go into the render stats for your sky dome and turn off final gather cast and receive under the mental ray tab?
