I have been testing how the radiosity in Vue 5 works for interior scenes. It seems like light just doesnt bounce of the surfaces as it should, and the renderings become to dark. Here I placed a spotlight in the corner of a room. The material is Flat White. I rendered the room with Global Radiosity. In the first image I had gain at 1, in the second at 9,75. In the firs image everything outside the spotlight remains almost black. In the second one the light is too bright and the room is still darker than it should be. On the right I added a heat map to better show the difference in lighting. Can someone help me with the correct settings, or is Vue just not made for real interior radiosity?

Heikki
