I'm trying to make a huge scene (10,000x3,012) and I've run into a problem:

The near backdrop is too short to cover the world, and the bottom edge appears.

I've tried resizing and lowering the backdrop myself, but that hasn't worked.

hmm, I've had that problem, but I don't know the exact solution. Play around with the scroll speed values until you find something that works is all I can say. Resizing won't solve your problem because it is set by the bottom of the bmp anyway, so changing the size wouldn't make a difference.

Thanks, I'll give that a try.
