Getting an accurate view.

I run into this issue loads, basically when I create a new particle sfx in the Magos Editor.
More oftne than not it appears vastly different ingame then it does in the Model Editor.
Is there a way to get a more "accurate" view of how a particle effect will turn out ingame?

World editor, sadly.

moyack has it right -- Magos' is as good as it gets outside WE.

Very well, i guess that trial and error is as good as it gets.
