The central base under your model currently pulls all the colour from the bottom edge of the skybox into the middle. It is a nice way to fill the base, but sometimes it would be better if the base could be defined without having to put a huge floor texture into your model.
Can there be options for the base? -
- mapped skybox (current)
- colour pallet
- pick a texture from model
- select image (stretch, scale or tile)
And some sort of blend to smooth the transition between the bottom of the sky box and the base?
