little bug with exposure...and workaround for it

[jan__]

Hi all

If you animate, for example, the ISO value in photographic exposure control, the value doesn't updates correctly at render time, only updates the UI. As workaround, you can use this "2-lines-simply-script" to "say" to max that this value has changed. Put the script on you scripts/startup folder or run from maxscript->run script inside 3dsmax

callbacks.removescripts id:#update_expo

txt = "global a = 0.0\n"
txt+= "a = SceneExposureControl.exposureControl.film_isoUI\n"
txt+="SceneExposureControl.exposureControl.film_isoUI = a"

 callbacks.addscript #preRenderFrame txt id:#update_expo

Hope this helps


UPDATE: animating shutter speed value instead of ISO value works fine
