Previously selected tile system preset is now automatically active when creating a new tile system.
Renamed "Default" preset to "Default: 3D" and introduced a new default preset called "Default: 2D". The main difference is that the default chunk size for 2D tile systems is 100x100 since this tends to perform more efficiently for 2D tile maps.
Collider type is automatically set based upon the default editor behavior when toggling "Add Collider" for tileset brushes. This provides a slightly smoother workflow for 2D developers.
The behavior of tile systems with sideways facing tiles has been adjusted to significantly improve workflow with Unity 4.3 sprites.
Until now tile prefabs have been rotated by 180 degrees to face away from the tile system. As of this version rotation is no longer applied for sideways facing tiles unless the new per brush property
Force Legacy Sidewaysis selected.
Any existing brushes will be automatically configured to continue to use the legacy sideways behavior upon updating this asset. This option can be toggled within the "Extended Properties" panel for affected brush types (oriented brushes and brushes which have prefab attachments).
Immediate previews are now rendered for prefabs containing Unity 4.3 sprites.
Fixed bug where tiles could not be erased when brush reference is null. For example, brush originally used to paint tile has been deleted.
