Orthographic projection camera and raycasts

Hello people,

I would like to click somewhere on the ground, and when i click, an hitmarker appears at the exact position on the floor i clicked, to show me where the raycast landed so my character can walk to this place.

I succeed to do something drinkable, thanks to this tutorial : https://developer.playcanvas.com/en/tutorials/simple-shape-raycasting/

But the problem is when i change the camera from Perspective to Orthographic projection, the result is incorrect.
I took some screenshots so you can understand.

Maybe the way to calculate raycasts is different with this kind of projection ? To be honest, i don’t know.
Any ideas ?

Thanks by advance.

Orthographic camera => https://i.gyazo.com/b9e260bf0304fd6e2c444279b1852319.mp4

Orthographic camera with different angle => https://i.gyazo.com/783b3b613ba0933350ec679a12fef1cf.mp4

Due to the nature of the projection of the camera, you can’t use the camera position as the ray origin. See: Raycast not working in orthographic camera mode
