The gui wheel event prevents the camera wheel event, how to block the gui wheel event, and only keep the gui click event?
You can disable the button’s pointer-blocking ability:

Hmm,
I’m sorry to take this opportunity to come bothering you again about this, but it doesn’t seem to quite work like this. Using a button, isPointerBlocker set to false does not allow wheel event. Setting the part of textBlock from the button also to false does not help either.
Furthermore, creating a rectangle and a textBlock and by default, the rectangle but also the textBlock (which supposed to be a pointerBlocker by default from my understanding) both let the wheel event through. However, even more interesting, specifying that the pointerBlocker should be false (or true) prevents the wheel event?!
Here’s a PG that illustrates this. At least for me (on chrome mac):
Edit: the button to the right is from a rectangle and the one to the left is a simple button
do I understand correctly, that when set to false (pointer blocker) your wheel event is not passed to the scene? i.e. - Simple GUI in fullscreen mode | Babylon.js Playground (babylonjs.com)
I guess so.
oops, forget it. typos error 
My apologies, it works (for both button and textBlock):
