Have you ever thought "Hmm I like this lighting setup but it's all a bit dim / too bright.." You can change the exposure values of Maya default and Arnold lights by a relative amount so that every light's exposure gets increased/decreased by the same amount.
By default this option ignores hidden/disabled lights
- Override: Absolute change -> sets all exposures to given a amount, disregarding current values
- Selected lights only -> Only effect selected lights
- Include hidden lights -> Effect hidden/disabled lights as well
You can drag and drop the .py file either:
- into the script editor and run it that way
- or from the script editor (while having it all selected) onto the toolbar to save it there for later use
- If you'd like to just set absolute values for multiple lights, there's already a built in function for it in the
Arnold->Utilities->Light editormenu - This project was mainly just a learning experience, but it might be updated to work with different renderengines used with Maya
