Not exactly. If the thing you are changing in the level has NOT been added as a track/section in Sequencer, then yes, it will change in Sequencer too because Sequencer is not driving that property. (If I’m understanding you correctly).
However, if a track for a certain property, such as transform or light intensity, is added to Sequencer, then Sequencer will maintain that property’s value regardless of what occurs in the level in the “background”.
Yes, I’d like to overhaul the Tips and Tricks page to include examples like this. “What context would you want to use Additive, Relative, Additive from Base.”
