How to change Motion Blur via blueprint?

I know how to change other post process effects through blueprints (“Make PostProcessSettings” node), but there is no Motion Blur Amount in there:

How to access the Motion Blur Amount value to be able to change it?

Argh just found it, it’s not named “Motion Blur Amount” but just “Amount”. Other settings have “settingName + Amount” names, so this one is different.
For others: Just search for “Amount” value, it’s above “Max” and “Per Object Size” values.
