This room contains no lighting at all.
It will load completely black.
It is intended for use with portable lights.
The walls of the cave are a crystalline pattern that only becomes visible when bright lights are added. Colours will change depending on the lighting.
Made for my own use so try before you buy.
There will be no refunds.
If you do not possess any portable lights I have several in my catalogue, both as accessories and as furniture, and there are several other creator who make them.
