After far too long, I've released a minor update to TyrLite which fixes a problem people were having using the color key in entities other than lights. Specifically, the program would exit if you didn't have three values in your color field. Some custom entities such as the popular force-field code use a single color value, so I have reduced this to a warning. Don't bother updating unless you are affected by this.
Last month, to go along with the screenshot I released here, I uploaded a set of three screenshots to Pipeline. Pipeline is a new site where map authors can upload screenshots of their work in progress so that interested Quakers can check out "What's in the pipeline...". I was holding off posting the info here while the site got some testing, but it looks pretty stable now so go check it out! You can get directly to my screenshots here, here and here.
