Hi , I'm new to Unity. I have made this little space ship to put in the Unity Store. It came out at about 5000 polys, mostly because of the engines. I was thinking of doing a couple of different paint jobs for it but would it not also be better to provide the original photoshop file in the download so that a customer can turn off or add their own decals etc.. to the texture using layers? Also, the free version of Unity does not seem to do shadows, can I make renders in some other package to represent my asset? Any feedback would be appreciated.
