I’d like the wiki to have something like a common misconceptions/FAQ page.
Please correct me if we already have this, but I do not think so.
Misconception: Lights are Spatials/Nodes
While you can add lights to Nodes this simply means “everything below that node is lit by this light”.
Lights have their own Position which you could change/update if you want moving lights.
There is a Light/Node bridge called
LightNode though, which makes a Light follow a Spatial. That’s probably what many people expect when adding a Light to a Node.
