Hey there, I’m fairly new to BabylonJS and found a weird behaviour which I’m not sure is intentional or not that’s causing a bug for me. Sorry if this actually belongs in Bugs!
On the actions page it says that the OnPointerOverTrigger and OutTrigger events are only raised once, however I found a case when they are raised twice instead. Whenever you scroll over a mesh that has raised that event once, it is raised a second time. Then, when OutTrigger is raised, whenever you scroll it is raised again.
Here’s a playground reproducing that behaviour: Babylon.js Playground
