Intersect Objects behind Html

[AlbertoRocaM]

Hi!

I'm trying to fire mesh events with the canvas behind the html. With the canvas in front there are no problems, but in this case they are only used in the background. Is there a way to make it work, changing the raycaster or something?

I have tried to change the raycaster but I do not know if it is not the solution or I have made a mistake when doing it

Thx 😊
