Using the VRExperienceHelper with an Oculus quest, I want to change the laser color from a controller, so, following the documentation, I try:

VRHelper.changeLaserColor(new BABYLON.Color3(0.5,0.1,0.1));

but nothing seems to change. On looking at the code while running, it seems that every time round the main loop, a call to \_castRayAndSelectObject is called, and this clobbers my laser color with a predefined one. Is this a bug, or am I just not understanding how and when to call the function.

Thanks

Seems like a bug. The color is constantly set, exactly as you described.  
Care to crate a GitHub issue for that?
