Here is a practice model that I have done. These days I can say that I will probably unwrap it, but not texture it.
I have kept it quite simple, as it would be very small inside CnC3.
As always I have made changes to the design where I see fit.
For Example I prefer a triple mortar setup, because I would have no use for a triple missile launcher that the concept suggest.
This would be unwrapped unto a 256x256 texture.
Any thoughts?
These bike more looks like trike :)
