Hi,
you could use a pre-render RTT pass with an ortho camera that just views
a part of the larger texture and outputs a Texture2D.

Yes, that was also my first approach, but I need a resulting Texture2D.
I'm working with an external painting lib, which requires a Texture2D as a
brush.
I'm painting tire tracks and the used painter draws on each animation cycle.
Therefore i use the tire rotation to calculate the current tire track
(normal&bump map).
