Quick Tip 3: how to control color and size of particles depending on velocity


I saw this simulation a few month ago and its realy incredible! vimeo.com/27431307
I tried recognize it in C4D a few times and it is my the third attempt. This is very fast render, so sorry for bad quality. I used realflow for simulation and TP for control size and color in c4d. Control colors of particles was realy hard task. Result is not very clearly with color.


I made 30 groups of particles, for each group setup own PShape with material (30 mat, 30 object, 30 TPgroup). And change group depending there speed. If you dont understood you should watch video.
0:22 – Setup simple emitter
3:05 – Control Scale depending on velocity.
5:30 – Convert Velocity(Vector) to Speed(real)
11:00 – Apply colors from image on mat.
16:40 – Setup xpresso for color changer.
22:10 – Making of “Liquid test 1”.
I hope this was helpful!
