- There would be fibres of plant tissue growing on the surface and in the Canyon.
- There would be water in the canyon, as rainfall would run off the surface of the leaf and collect in the fissure.
- The walls would be quite bright as they would be on the leaf, which has a lot of Chlorophyll and seeing them this close the surface would look almost celluar.
I tried to replicate it in Maya by creating a shader. It could still use some work as it looks a bit 'plastic' but I think it's getting there. Below shows the simple shader and the result.
I've drafted the scene as I imagine it. There are fibres sticking out of the plant canyon wall and out of the floor. The canyon is slightly submerged from the rainfall and the surface is bumpy. I'm sure there are a lot of changes to make before I'm happy with it. If anyone has any ideas or can point out an scientific inaccuracies then that would be helpful.
