Ok solved. Seems model textures can be made to default to one of the channels but this requires 3DMax or some other model making software.
Contribute to the wiki (Wiki button at top of page) Considered easy altering of the unit textures?
What about custom models automatically being set to a specific channel?
So definitely no possible leads for RTT outside cinematics?
Was hoping to be able to be able to turn some doodads into live monitors without locking the player in cinematics mode.
I know the Set Camera Channel action can use a camera from the Actors data type to view through various channels but how can you set models/textures to use the channels?
