zasid Posted July 26, 2011 Share Posted July 26, 2011 Hi, I have seen a tutorial but can't remember it anymore where to find this. What's the best way to randomising point normals and controlling their direction and using there radomisation to feed particle as velocity. I will be thankful if someone remember in which tutorial I can find this info or posting a simple file which I can check out. Actually what I am looking for is to have full (procedural control) over the normals direction and randomizing the values in some way to be used as velocity force to push particles out in the direction to get some sort of sand splash setup. I tried the point sop to generate normals but not having much luck randomising and to have full control over their direction. Thanksalot.

lukeiamyourfather Posted July 26, 2011 Share Posted July 26, 2011 A VOP SOP network would be best for this. It allows for point manipulation (attributes, normals, position, whatever). You just can't create or delete any points using it. Quote Link to comment Share on other sites More sharing options...

Check out this ancient thread about random where Mario edumacates on the randomness of random.... (or lack thereof, however you choose to see it...)
