well, theres a couple things that need to happen....
- the bridge exemplar would need a new ID, the model exemplars would need new GID's (if changing network type) and IID's.....(essentially, this means a completely new bridge file)
- the model IID's would need to change as well. otherwise, any bridge file calling that model ID would have the new texture....
- the transit texture would need to be changed. there are 3 instances i can think of...
- the transit texture was added in the BAT, and cannot be changed directly (some bridges are currently like this)
- it was added via T21 by the model exemplar (can't think of any beside my beta bridges)
- it was added directly to the model in the reader (most NAM bridges are done this way
there's different methods for each.....i know there's a way to remove sections of a model in the reader, but im just not sure how.
thats it in a nutshell.....
