VR Expansion Plugin

Hi again,
i am trying to change recoil parameters of the GunTools script during runtime in order to apply changes to the gun recoil when attachments are being attached to the gun. According to my debugging my changes are being passed all the way into the script (using a reference to the gun tools script and the Set nodes for respective values), however the ingame gun recoil doesn’t change. Should i be able to change gripscript properties during runtime or am i on the wrong track?
Cheers

Edit: In the meantime i found that my runtime adjustments to the properties of GunTools script work, however actual gameplay recoil is only affected if “Apply recoil as physical” is unchecked. If recoil is applied as physical the changes to properties have no effect. Would you briefly ellaborate why is? Thx in advance!
