Re: Mental Ray Exposure Modifier
actually, i only had a chance to install it. my initial reaction was that it was the solution to the problem, but on closer inspection, it actually is not. i read Zap's blog post about it, and he clearly outlined that he created the script because this is where he felt the information needed to be rather than the environment roll out. he also made it clear that the script he created simply called the ones in the environment, and was in no way a solution, but more of a concept.
here is the basics of how his the script works...
you go to the camera create panel as you normally would. if you have the script installed, there will be an option to create a mr camera. you create that, and the camera controls are then part of the modifier tab. you can adjust the shutter speed, f-stop, ISO and a couple of other things.
the shutter speed, f-stop, and ISO in the modifier panel are scripted to change the information in the environment roll out. when you change the number here, it changes the number in the mr photographic exposure settings in the environment roll out. so yes, you need that enabled.
i was wrong in saying you could not control the white balance. since you still use the mr photographic exposure enabled, the white balance is still in place.
where this script fails for me... it is not on a per camera basis. i was hoping that the camera settings were attached tot he camera. if it was on a per camera basis, then when you switched cameras, the f-stop, shutter speed, ISO would all change to the settings needed for that camera.
to me this script suggests that a per camera might be possible if i had a little knowledge in the scripting department. which i do not.
