Well, you could buy one, borrow one, steal one, film with a blue shirt and I can color correct it, we have many options.

Yeah, in the US we got a very funny post-credits bit where it's just all the characters at whatever that diner Stark was talking about, eating, all visibly in shock. Goes on for like twenty seconds, nobody says a words. Cut to black.

Got a huge laugh.

Hey, who was the pink guy in the first end credits scene? The guy who's gonna be in the sequel?

Guys from Breaking Bad.

I for one have bought Pink Five at least six times.

I liked Transformers 2.

Another thought, you don't have to move the camera through the tube. You can have the (static) tube animated to wiggle around like a snake being held by the head, and move the texture past the camera.

Easier than splining a path through a squrimy tube. Just a thought.

It looks like a lot of what's missing here is lighting in the tunnel, and then, once there's lighting, the illusion of depth into the swirling fog. What you have here is rather flat.

I'd probably avoid particles pretty far into this project, and do it with a bunch of circular cloud cards with a feathery hole in the middle. Like, forty or fifty of those (you could set it up as a batch action in Photoshop, and just print out fifty different ones) and string them out into a tunnel in the 3D software.

I'll do a test a bit later today if I have time.

BUT YOU HAVE TO

RIGHT NOW, STOP WHAT YOU'RE DOING AND WATCH THEM

If I keep doing this long enough, Dorkman will never see anything.

...that's scary.
