Skydome with VRayGeoSun

[stezza]

So what is the correct way to combine the skydome HDRI with the GeoSun?
I need to have some clouds in my animation which is using physical sun but this on it's own gives you the flat blue sky which I need to replace with clouds.
I dont necessarily need the hdri to effect the scene as the light from the VRay sun and sky give a good result.

How is this set up?
Many thanks

From what I understand you simply need a cloudy background without an effect on the scene's lighting? You can do it with a VRayDomeLight which has its Affect parameters (diffuse, specular, reflections) turned off; this way it would act as a background.
