yes, thanks for the reply. you're a great moderator
you mean... yes I use the radiosity override material. But I don't know how to set the parameters to simulate materials properly... I mean.. Why do you want a light analysis tool if you can set the light properties very well but it's difficult to set material properties?
in lightscape, for example, you had some presets for different materials,(wood, concrete, plastic, glass etc) but here in VIZ I don't know how to set the materials for radiosity. is there any tip on this? thanks
