Thx.I’ve tried to find it here as well.but they’re not exactly what I want.but thx anyway.
and I tried to apply the vector effect from the Gak Pak effects.and I managed to make this tunnel which is what I want to achieve.https://sweb.cityu.edu.hk/50694070/tunnel.mov
But still I want the tunnel to be circular rather than rectangular.Does anyone get any idea for changing it to a circular one?thx a lot!!
