There are these animated water effect tiles named shore01.frm through shore10.frm. I am using them and they look great. I'd like to figure out how to modify the colors, and make some east-west shoreline tiles. But how do these things work? If I convert them to gif they are not animated. And if I view them in an FRM viewer they are not animated. I remember a thread some time ago that talked about some special encoding that is used for animating some scenery like terminals but I can't find that thread. Does anyone have any technical detail on this?
