Hi, all.
Happily, WZ4 has a dedicated op for this!
Check this one out.

A classic but still a cool effect, thanks for your share

I never expected wz4 to natively support such effect and was really surprised.
I always thought that such things were done by moving a pivot point of a torus and rotating it 'through' a static camera
or by attaching a camera directly to the spline used to 'sweep' the tunnel mesh.
So, fr guys combined these two methods and it works really nice!

there is many way to create this effect. You can also animate a deformable cylinder with sin and cos in x,y axes with a static camera at beginning of cylinder, and add an anim texture on z axe to simulate the moving.

there was a few years I had done this snippet : tunnelOpengl

Good approach. Wanna try it myself.
Take a look at my attempt

nice.

Great examples.
I´ve done something similar back then with .wz1.
It´s pretty simple but with the right animation it should work well.
