Ok, so I've created my own map for The Lost City in Gimp, and on Tier 3, there's this little central rotating corridor. It looks like this: I've made the central part a separate overlay that locks with the grid on and rotates, thusly: What I want to know is: how do I use Dynamic Lighting in a setup like this, so that the DL lines follow with the central circle as it rotates? I'm assuming there's a script for this, but I don't know what it would be. EDIT: Also, it would be really cool if any tokens that were in the corridor while it rotated would move with it, but that may be reaching a little.
