OpenGL 3d Window so Dark

[Anonymous]

It's so dark in here, I might fall and break my foot.

The walls are pitch black.

I've played with the sun and its angles and all the settings in 3d projection settings window, but it's still as dark as the corners of hell;)

I've tried changing material on the walls and surfaces; should this have any effect?

I'm using Archicad 20, with OpenGL.

ok, I'm getting closer; I manage to change surface and now I can see.

I SEE THE LIGHT

I SAW THE LIGHT
I SAW THE LIGHT
NO MORE DARKNESS, NO MORE NIGHT
PRAISE THE LORD
I SAW THE LIGHT
