i have a scene with multiple active cameras, each having a set viewport (e.g. two cameras as split-screen) and that works fine. const cameraOne = new ArcRotateCamera('one', 0, 0, 90, new Vector3(0.5, 0.5, 0.5), scene); cameraOne.viewport = new Viewport(0.0, 0.0, 0.5, 1.0); const cameraTwo = new Ar…

figured it out - in case of multiple cameras/viewports, pointerInfo.pickInfo is useless. instead need to determine in which viewport click occured (check bounding box vs mouse coordinates) run scene.pick with specific camera parameter that matches the selected viewport const pickInfo = scene.pic…

I think this playground reproduces a similar effect. the button on the left doesnt work, while the button on the right does. Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes

Seems it depends on active camera’s order at the moment. with scene.activeCameras = [camera2, camera] the left button works and right doesn’t.

hmm, I wonder how it would work when two cameras are on top of each other, maybe in some kind of window system

i’d expect it to pick the top-most mesh that doesnt have a mask set. same thing if there is a single camera and there are multiple overlapping meshes.

that seems like the most intuitive behavior to me also. it’s still relatively early in the US, hopefully someone from the bjs team will be able to give a proper reply soon.

Apologies for letting this slip through! Scene has a cameraToUseForPointers parameter ( Scene | Babylon.js Documentation (babylonjs.com) ) that can be used to specify which camera you want to use, but I feel having the capacity to run pick for multiple cameras at once would be useful too… @sebavan @P…
