Didnt realise that last post was part of the Maya help section on particle instancers

Mirek,
I've just added some basic instructions on how to replace the particle geometry with your own into the readme file in the 0.2 zip file on my site. At a later date this will all be integrated so you wont need to mess about doing it. I'm guessing I'll add a button so that you can select the model and press it and it'll do the rest for you
