We're currently writing an indepth tutorial on how we made our capture system. Here are the basics:
-We copied the pylon power radius actor and model (requires changing texture paths in the model file with an hex editor)
-Since sc2 has problems with big projector textures we had to cut it into 5 pieces, 4 actors for each corner and one for the center glow. Siteoperator actors were used to change the offset and rotation
-Use send message to actor in the trigger editor to change the colour of the actors.
The minimap tiles were made by placing a dialog window over the minimap and adding images where each flag is. The colour changes each time a player caps a flag.
Were you able to make any headway on the trigger issue with NA servers?
I got sent here from http://forums.sc2mapster.com/development/triggers/11710-creating-3d-ui-elements-lines-on-terrain-color-fills/#p18 Can anyone elaborate on this? I can't seem to even find this "pylon power radius" actor/model/doodad/decal. I'm pretty new to the editor and tend to get tunnel vision when I look at the data UI, but even so it seems like my searching should've brought SOMETHING up. I must be way off.
