The ground textures look really nice.
Please correct me if I'm wrong. But I don't think there would be that much water inside a deserts' landscape.
This is true, and originally I wasn't going to have any water at all, but that wouldn't be fair to the CV lovin' folks, and I want to make sure there is something for everyone to enjoy.
Will HiTech allow custom ground textures now? And will the trees/shrubbery look ok on a desert setting?
Custom ground textures have always been allowed. You just have to be sparing with them for file size reasons. The nice thing about this new terrain engine compared to earlier versions is that a custom ground texture only requires one .bmp. The old versions required three, the texture .bmp, and ovly .bmp(transition) and a ovly_a .bmp (how the textures would squiggle together). So now you can have a custom texture at a third of the file size, compared to older versions.
As for the trees & such, we have a choice of the Pacific set, or the European set, so I went with the Pacific i.e. palm trees instead of evergreens. I'll post a ground level pic tomorrow.
