I'm using 2D Toolkit to render my own isometric tiled map with tk2dSprites. Drawing tiles in the correct order for isometric maps is very important for making sure it looks correct. I am using the sprite's SortingOrder to do this, however it seems that any number higher than about 5000 makes the sprite disappear completely. A SortingOrder of 4000 works fine.
My isometric tiled map has up to 26000 tiles and so up to 26000 render layers. How come the support for SortingOrder seems to cut off around 5000? Is this a bug or an intentional restriction?
The new editor variable for this is labelled "Sorting Order In Layer" does that mean I can group sprites into Unity Layers for further draw order control? Or does that have to be done via Z axis manipulation?
