Dragon corridor v2 — Threading the needle
The same flying snake, a meaner corridor: the obstacles become pierced plates it has to thread rather than slabs it can slip past.
Same construction as v1 — one raymarch for the whole scene — with the corridor and its obstacles changed in character. The dragon no longer chooses an open half; it has to line itself up with a hole and go through it, which turns the weaving into aiming.
Watching it commit is the point: the hesitation before a hole and the recovery after one are what make a shader look like it has intent.
