  1. flip fluid- sop solver vs pop wrangle

    Hello, I am currently diving into flip fluids and I have a few questions. What is the difference between the sop solver and the pop wrangle in dops ? If I were to set @v=(1,0,0) in a sop solver and then the same thing in a pop wrangle I will get pretty much the same effect...so what is the point of the sop solver? More control? Is the sop solver doing something intrinsically different than dops ? Isn't the point of a sop solver to basically remember the previous frame? Isn't that what dops is doing already ? Thank you
  2. intersect function and Normal

    @LibrarianThank you
  3. intersect function and Normal

    Hello I am working thorugh this rock modelling tutorial here: I am at the part 15:28 where he fixes the intersecting geometry using an intersect function. The code he writes is: vector p, uv; int hitPrimIndex = intersect(0,@P-@N*0.001), -@N, p, uv); if (hitPrimIndex == -1){ i@group_intersection =1; } For some reason it is not working for me. He is working with prims but he is plugging in the N attribute which is points. For some reason it works for him but not for me. I will attach my file for anyone that wants to take a look Thank you intersection_vex.hipnc
  4. Attribute stamp not working

    @anim Got it working now. I also got the h18 copy to points working as well. Its way simpler. Thank you anim ! Cheers
  5. Attribute stamp not working

    Hello, I am trying to copy random voronoi pieces to my points I created a random attribute on each point to use as my stamp: i@rand=int(fit01(rand(@ptnum+234), 1, 46)); I am deleting each piece based of this attribute and feeding it into a copy sop. I made sure to put my rand attribute in the "Attribute stamps" parameter on the copy sop I am not sure why Im still getting one piece copied onto the points. Please help. Not sure I understand this well enough. Thank you rand_stamp_copy.hipnc
  6. Hello, I am working on setting up an agent for a ragdoll simulation. Is there a way to visualize the bone names in the viewport like you would for an attribute? Thank you
  7. crowd test transitions

    @Skybar Thank you for the response. I am trying to do it without the crowd transition graph and I am getting very strange results. I have linked up the crowd state names inside the crowd transition node properly i think. I was using the stadium example as a guide. Not sure why this is happening... Thanks h17_crowd_rd4.hipnc
  8. crowd test transitions

    I have got a little farther with this. But still can't make it work. Anyone ? h17_crowd_rd2.hipnc
  9. crowd test transitions

    Hello, I am trying to get my transition graph to work. I want to go from "idlle" to "idle_to_walk" to "walk". I am trying to follow the crowd example from the shelf but I still can't seem to get it going. I have successfully simulated and randomized my clips in dops but i'm not sure how to get the transitions to work properly in h17 I will attach my scene file for anyone that wants to take a look Thanks h17_crowd_rd.hipnc

  12. Velocity offsets point position from sops to dops

    @vicvvshThis is exactly what I needed. Thank you @karanjauraThanks. Your file is not working for me. I think that is a digital asset you installed. Seems interesting though. Where did you get it?
  13. Hello, I have a question about bringing in points from sops to dops for a FLIP simulation. When I add velocity to the points in sops, the points get an offset in dops based on how strong that velocity is. If I were to multiply the velocity in sops by something strong like 100, it will be offset even stornger in dops. I am trying to get the point positions to stay in there original position coming into dops. I know how to fix this issue in a particle netowrk setting the "Jiter Birth Time" to "none"..but how would i fix this with a FLIP sim ? I will attach a scene file and screenshots for anyone that wants to take a look. Thank you. flip_point_offset.hip
  14. random translation in for loop

    @toadstormthank you for the tips. I got it working
  15. random translation in for loop

    I am trying to randomly translate on the y axis using a for loop. I have successfully randomized the color but for some reason I can't move them upwards. int i=0; vector rand=rand(@class*234.234); f@randY=fit01(rand(@id*234.234),2, 12); for(i; i<10; i+=1){ v@Cd=rand; @P.y=@randY; } What am I doing wrong here? translate_forloop.hipnc
