hello guys . i made a simple ray attached to a mesh then i used ray helper to see it , it works just fine .
but when i make the mesh moves, the ray start disappearing and appearing in a weird way after some time (depending on the length of the ray).
i don’t know if the ray disappears or only it’s visualization of rayHelper .
this is the PG:
please help if you have any idea why is doing that . thank you
