Thanks Lisa,

yeah, it's better than I thought it would be. Pixel slip was pretty good I think, below 1.0, something like 0.8... cant remember exactly...

Something I was wondering about though, in the clip featuring the hallway, I wanted to do a test animating something like a spider crawling on the wall (nothing major just a test).

But when I put a plane in to simulate the wall, it didnt line up that well. Could it be that my hall isnt straight, because I took meticulous measurements for each track point?

Oh yeah, one other thing, I want to change the scene so the origin is better positioned for animation (points constraint or something?). Do you use this feature?

Thanks for reading,
Couldn't have got this far without your help!
