When creating "Engine Flame" polygons for BZ2 vehicles in MAX, the XSI converter mixes the verticles sequence and that creates
very weird looking effects in game.
Below I will explain a very simple way to repair those polygons.
As you are working on the model, and once the polygon for engine flame is created, make sure you name it properly( flame_#_h ).
Switch to verticle selection mode and select every verticle and make a scetch of their location as shown below.


Once the model is finished, export the XSI file, and test it in game if you like.
OK, now we can start fixing the flame polygon.
Open the XSI file in Notepad and find the frame " flame_#__h ", as you see bellow the MESH flame_2__h part states a location
of each verticle and then follows with triangle creation. In the highlighted area the first line states how many triangles are used to draw
polygon, then the folowing lines state which verticles create the triangle.
In order to fix the polygon, I just create a single quadrange using all the verticles.

Below is the final change to the file.
I hope this helps you guys.
