alright I had a little set back, I went to edit a few things and something screwed up, couldn't tell you what it is but I had to recreate the domino's but I got it all working... I made each domino a little more detailed (just a few more poly's for smoothing purpose), and now when I simulate it takes FOREVER! Any way to reduce the amount of time it takes to simulate these dynamics or am I stuck with them loading forever. I keep simulating over and over after every little tweak to see what I'm doing and these simulation speeds are slowing me down a lot.
