Hey guys!
I recorded a free tutorial which you can find on my Youtube channel where I go through the process of generating a rock pile through instancing, using the new feature in Maya Ext 2, MASH. I have also provided the scene file for a small cost which contains the lighting I used as well as the rock assets and all of their textures. Check it out on Artstation to watch the tutorial: https://www.artstation.com/artwork/9RknL
