To be honest, just looks like you gave it a refracting material unlike the first video.
The first video's particle system is not only ugly (that's where the refract comes in) but his settings for collision are off.
It looks and acts more like ice sludge to me, but it's pretty cool. Good job.
I need a better texture :( Is it acting like ice because it's moving too slow?
I can't really see a lot, you should make it brighter.
Are you watching in HD? I can't figure out what to use to make the video brighter.
The physics on the water aren't that realistic though.
I haven't messed with the advanced features of the particle editor yet, mainly because there's no documentation on it. I'm sure there's something in there to make it act better.
Hello awesome hidden water fall bases
Fucking awesome idea!
There's now a download link if you guys / gals want to mess around with it.
