Rence Posted January 16, 2018 Share Posted January 16, 2018 Hi guys, I am trying my best to figure this out. I have a ray node and instead of the scale value animating from 0 - 1 and the whole mesh moving at once, I want it to animate from the bottom up. So I added a point sop and added color ($BBY in the red) then I added a pointvop and in there I extracted the red and set it to a ramp parameter and animated the ramp so the color now fills up from the bottom. Then I have the ray node, set to Minimum Distance. I want to enter in an expression into the Scale input that I guess tells the ray sop that where there is color, those points should move to the collision primitive. Is this possible or am I going about this the wrong way? Quote Link to comment Share on other sites More sharing options...
Sean-R Posted January 16, 2018 Share Posted January 16, 2018 It should work if you write @Cd into the Scale parameter. Quote Link to comment Share on other sites More sharing options...
Rence Posted January 17, 2018 Author Share Posted January 17, 2018 Thanks Sean, Yeah it does. I had setup my color wrong in the point vop. I had a white to red ramp instead of a black to red ramp! Quote Link to comment Share on other sites More sharing options...
