I can't seem to get it to work properly, I import it and it seems more like just a bunch of particle emitters that emit a smoke-like texture. Those rings that yours has don't show up and the bright plasma that indicates where the missile actually isn't seems merely a light emitter.
Am I doing something wrong here? All that comes with this download is the model itself, so I imagine it uses in-game textures... but why does yours look so much better than mine in-game. |
