Good to hear you found the solution. Also in connection with your reply to my post, it's one of those times when it is nice to be wrong!
Without the fix it would have been difficult trying lots of textures for suitability for models like this.
Thank you for 2.5 Beta
I'm not sure how the global illumination works in Sweet Home so please ignore this request if I have misunderstood.
While you are working on 2.5 would it be possible to adjust the sunlight position within sky dome, so instead of the light being outside of the texture dome it could be just on the inside? I am just thinking how much light reduction happens as soon as a sky texture (even a light coloured one) is applied.
