[antho2b]

hi guys
I'am using keyshot since few day and I use to do indoor renders 
I have try some stuff but apparently without big success

increase the number of ray bounces... creating a square in front of a window and apply a light on it. But as long as I keep the ceiling shown, it's all too dark

I actually don't really what are the overall general setting used in keyshot to be able to render in indoor, I generally have to do this type of render :
so I want to be able to render inside boxes where light only enter by window.

Have you tried to use area diffuse light, point lights and/or IES lights?

I have tried area plan, but where to put them ? do I have to use the floor as a light ? too creat plan in front of windows ?

some of the render you saw above are made with point light but that not the easiest way to light a whole sceen...
