Problem importing prefab into another project

So I imported a fountain in Unity from Maya and did all the particle effects for the fountain and put them in a prefab. When I try to put the prefab into another project, only the particle effects come in, not the fountain. Here’s what I have done so far:

*Exported the prefab with the fountain and particle effects and used the import function in Unity.
*Dragged the model into the project, and then the prefab.

Any help is greatly appreciated!

im a big fan of asset packages- but i think you have it but your missing the most important part… you need everything associated with the prefab when moving them between scenes. So you most likely have and FBX from maya of the fountaint, once adding that to your scene it contains all the transforms and whatever elses. So if you make a prefab of the fountain that is now contained in the project somewhere you can grab it, the base geometry (the fbx) the particles, textures (everything accociated with the exported) and go to assets- export package. Now this way it does a good job of grabing the dependancies ( ie, textures, materials) and exporting those along with everything ( thats why i like it, i dont have to track textures and materials down) the import asset package into new scene, and drag prefab to new scene and you should be good
