Shadows and World Size

This may see like a silly Question, but does the scale of your World effect Shadow Rendering? It seems like shadow casting works better with scaled down levels, instead of levels that were exported to egg on a larger scale.

Unfortunately, unless you use stencil shadows (which you must code yourself), you’re right: Larger levels have lower-quality shadows. There are ways around this, most notably PSSM, but it’s not easy.
