sky dome render too dark

[veej]

Hi all,
my first post here, so please bear w/ me.
This is also my first attempt at a v-ray render ( awesome app). However i was not crazy with the default sky so I used a sky dome. (a dome w/ a sky jpg map)
However I notice that there is an immediate loss in Brightness w/ the sky dome (as if the dome is blocking some of the light). I thought that maybe the SU materials are not great with vray, however this could not be the case as the default sky rendering has the correct brightness. (see images) It makes the rendering look like a Victorian era painting style (not the look I am going for!)
Please could someone tell me the issue. I would really like to use the sky-dome trick

sky dome render too dark

in shadow settings tty turning light up to 100 and dark to 0 and see if that makes any difference, make sure you have default lights check in global switchs

Mike,
am a first time user, so you will have to elaborate:
what is tty?
also could not find the shawdow setting in vray render options. is this a sketchup setting or a Vray setting?
I found the Global light switch and yes it was checked
thx

Your sky dome is most like blocking the V-Ray physical sky. If you would rather use your own sky dome than the physical sky you will probably need to create some emitters to provide extra light to the scene.

Emitters are necessary because currently we don't have our direct light sources hooked into V-Ray SketchUp, we will be adding them in the future though. To use an emitter just apply a plane or some object with a V-Ray material that has an emissive layer on it. You can control the brightness by adjusting the "intensity" param of the emissive layer.
