Hello,
When i run my project on mobile view everything is working ok without gesture. I cant move the camera as I am moving using mouse from pc.
Hi, what orbit camera script are you using?
The one include in the model viewer starter kit does work on mobile.
I don’t seem to be able to open it, but try creating a project from scratch, select model viewer and check it on mobile.
var OrbitCamera = pc.createScript('orbitCamera');

sorry i have to post here this big code but the sharing didnt working .
and i am creating configurator this is someone code.
@Leonidas
the work is too much hard to start from sctrach would you spare sometime and tell me the issue thanks sir.
