Linking mesh and particle effect is pretty easy. Install yourself particleforge and start it.
If you install particleforge in an own folder, be sure to have the subfolders
in it and in them any file you reference.
In particleforge, when you create and select a new emitter, you can assign it a mesh under ParticleMesh/Filename
For editing purposes, best open the files from your local folders.
To make it usefull you will have to assign it the shader "GsShip" if you want to use the same texturemodel as on ships (cl, nm, da) or any other if you think it fits better.
last, when your particle is ready for use ingame, you need to change the path of the mesh from something like
This path seems to be replaced by the game for the real path sins looks for the mesh (in our case the mod folder)
then place the mesh and the particle file into the respective folders in your mod folder and start to test (after assigning the particlefile to the respective entity of course)
If you got any further questions, just pm me or ask in this thread.
