Hiya Chapawee! :) Did this happen right when you exported the map or you went to go see it in the game?
First off, it's best to try and change your rendering system: -Click me- (http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=43234.0)
If that doesn't work, you should try searching "particle" on your computer since they sometimes find them self in other folders such as:
- particles
- exports
- and my_objects.
It also wouldn't hurt to check in my_objects for doubled meshes/objects .
Lastly, if you look in exports, it there's a double of the maps's fhm, delete it. It'll look like this:
Map.fhp ----> Map.fhp(1)
That crashes your game.
Haha, no problem. Yep, that happens to people on occasion.
