this is more of a tip since i’m not going to explain everything fully.
you may have noticed the fluid particle system recently, however i didn’t fully understand why i would use them if when rendered it just looks like a bunch of small balls clinging to each other kinda like this. http://www.youtube.com/watch?v=DoPUbFri0w4
however i found out about something called a meta ball, these balls sort of connect with eachother if brought close enough, i imediatly thought of using these in fluid particles, it took some testing but i did get it to work heres the same simulation while rendering it with meta balls. http://www.youtube.com/watch?v=poYhxswbLBY
see the difference, although i’m still testing this stuff out i thought i would let you guys know that it does work, also it allows you to do raytrace transperancy like this.
… sorry can’t seem to get the image to work. i’ll try getting the image up in a bit.
