I didn't know something like this was possible. Definitely mind blowing. I can't quite understand how it works, but I might explore the map files at home and see how is it done, try different settings, different setups, etc. Maybe I'll be able to get into it. I don't think I'll ever use it though. |

Impressive. Curious that this hasn't found its way into more maps. |

I remember this from back when that concept map came out with the swinging cross. The main barrier to implementing it is it's a big hassle to put together and has some fairly severe limitations (needs a stark single light source, entire shadow area must be inaccessible to players, looks wonky from extreme angles). If I remember correctly it's a riff on how cel shading was accomplished (an automatic offset around existing model geometry and then using the depth pass to 'draw' the outline between the offset volume and inner model volume). |

I have also been thinking about a use case for this, it's tough, maybe it could be interesting if you have something like moving platforms in your map. Other than that, I struggle to come up with something. Thanks fkd for pointing out the typo! I will fix it the next time I update the site. |

I was there Gandalf. I was there seven-teen years ago. I was there when the post was written.  This is a blast from the past. I still remember writing the first post all those years ago. I've updated the links on the first post to point to my Github account. There are some other maps on there too. |
