Right now, EoTech and other collimator sights have a fixed brightness that is not always idea. For example, against a bright background a low-intensity red dot is hard to recognize, while under NVG's the low brightness is just right, and a more intense reticule might make aiming impossible. It would be nice to have a brightness control. This could be simply an animation in the model.cfg that exchanges the collimator dot with different textures with different material settings.

Note that this somewhat ties in with issue 5323 (http://feedback.arma3.com/view.php?id=5323), as it could also be implemented as a simple new anim source for model.cfg. Theoretically it could be implemented via the same source and switching sights, but this would not work for scopes that have a backup sight, so an extra source would be the preferable solution.
