Time to try something new...
My first cave - and the name? Why Devils-Cube Cavern?
I modelled it with more than 60 displaced cubes... built like an igloo.
From outside (the bright spot in the middle is an emergency exit at the rear of the brigands and pirates

[attach=1]
From inside
[attach=2]
(quite dark inside but that will be neccessary for the story in the animation - I have already planes with it... again...

)
As usual "optimized" for fast rendering in 720p for my animation plans. Perhaps I'll try some HQ renders as stills too.
The mushrooms are from TF3DM, the lizzard and some moss is from archive3D and the rest of the plants XFrog
