Old MaxScript?

I watched this video

and it seems like it’s a good one, but the maxscript his used seems to be missing. Are there any available for 3DS max 2015?

If you need a better way to play back Particle Flow simulations then you could take a look at MegaCache as that exports Particle Flows that can be imported and used inside the Unity Particle system itself instead, allowing you a load more options than the bake to mesh option shown in the video. There is a video below showing the system.

I’m looking for something a bit cheaper. Something in the range of free, lol.
