Camera Tunnel effekt / transition


does somebody know if its possible to achieve a tunnel effect which should simulate a transition?

I have a start screen and want to make some kind of tunnel effect to have a transition from a start screen (video Texture) into the 3d scene. has somebody experience with this kind of effect and how to achieve it in PlayCanvas - or some ideas?


This tunnel effect should have a start and an end - but alternatively you could blend it in and out too.

Thank you very much for any inputs!
