Common creator pitfalls

If your color map and impassability map weren't exported at the same DPI, the route overlay will be visibly offset from the terrain. Always export both at 508 DPI.

Forgetting to click Entire Map in OCAD's export dialog produces files of different sizes. The two layers won't bind correctly.

If you skip the impassability touch-up step, the AI may happily route runners through stone walls or across rivers. Spend the ten minutes — it's worth it.
