Since I'm on Holidays from 7th to 22nd of September, I have to post this a bit ahead of time: 2D ColliderGen v1.2 has been submitted for review and will (hopefully) be released very soon on the Asset store! The most important big new feature is the support for unlimited collider-island and –hole regions within a single texture image! Hope you like it! If you have any questions in the meantime, please be a litte patient since I have no internet-connection in the following two weeks. I will however get back to you asap thereafter! Cheers, Harald The full Changelog comes here: New Features: Added support for unlimited collider-island and –hole regions within a single texture image. Islands and holes can be enabled and configured via a new 'Holes and Islands' section. Added support for OTTilesSprite. Simply add an AlphaMeshCollider to a GameObject with an OTTilesSprite component to generate colliders for it. Added a "Custom Texture Region" section to the AlphaMeshCollider parameters where you can specify a custom region to be used for collider computations (e.g. to use a custom frame from a texture atlas or spritesheet). Bugfixes: SmoothMoves related: Collider scale was wrong when setting a custom image at a generic object (e.g. a plain quad) which had no SmoothMoves or Orthello sprite attached. Colliders attached to SmoothMoves BoneAnimation sprites can now scale along with it. Added an AlphaMeshCollider toggle parameter "SmoothMoves Scale Anim" to enable this behaviour. 2D Toolkit related: Changed the location of the ColliderGenTK2DParameterStore code file from Editor to Scripts directory. This prevents a problem that occurred with later versions of the Mono Compiler. Unfortunately, all ColliderGenParameters.prefab files that stored parameters for convenience of each sprite in a collection are no longer compatible and will be treated as non-existent.
