Request: Global exposure override for Physical cameras

[windowlicker]

Somtimes I have a lot of cameras in my scene which all have the same exposure settings. When changing the light in the scene, it's a bit tedious going around adjusting all of the cameras. Also, when rendering stuff like a vraytoon pass, it would be very convenient to be able to flip the "use exposure" switch on or off globally.

Maybe there's a script for this, but it would be nice (and simple?) to implement in the render settings somewhere. Thanks.

Agreed. I also go through these issues.

Well, you can always turn off the camera exposure and use the color mapping settings instead.

Here's a quick script to turn off the camera exposure for all cameras in the scene and then, if you want, restore them back to the way they were).

global dp_camsExp = #()
global dp_camsVig = #()    

rollout CamExp "Camera Exposure" width:214 height:63
(
    checkButton ckb_camExp "Press to turn exposure off" pos:[17,16] width:181 height:33
    on CamExp close do
        (
        if ckb_camExp.checked == true then if querybox "Do you want to restore the exposure settings?" then 
            (
                for i in dp_camsExp do 
                    (i.exposure=on)
                    
                for i in dp_camsVig do 
                    (i.vignetting=on)
                    
                dp_camsExp = #()
                dp_camsVig = #()
                )
            )
        
    on ckb_camExp changed state do
        if ckb_camExp.checked==true then 
        (
        for i in cameras do 
        (
        if (hasProperty i "exposure")==true then 
            (
            if i.exposure==on then append dp_camsExp i
            if i.vignetting==on then append dp_camsVig i
            )
        )
        
        for i in dp_camsExp do 
        (i.exposure=off)
        
        for i in dp_camsVig do 
        (i.vignetting=off)
        
        ckb_camExp.caption = "Press to restore exposure"    
        )    
        else 
        (
        for i in dp_camsExp do 
            (i.exposure=on)
            
        for i in dp_camsVig do 
            (i.vignetting=on)
            
        dp_camsExp = #()
        dp_camsVig = #()
        ckb_camExp.caption = "Press to turn exposure off"
        )
                    
)
