anyone ?

Hello, So I am using the "Smoke Trail" Shelf tool on a simple emitter flying through the air. I want to be able to cache out cluster 1 , cluster 2, cluster 3, separately . Is there a way I can call it out from the dop import node? clustering_import.hipnc

i switched the constraint type to "both" instead of rotation which fixed it ...but now but now they seem to be spinning way to quickly. ap_constrain_to_animated_anchors_soft_rotation_v2.hipnc

both these methods work great. thanks guys,.

Hello Seems like i am stuck on something simple but not that simple. I have a tube with no subdivision. I am trying to get the normal to point along the edges of the tube . I managed to get it using some simple vector subtraction. The problem is when I try and scale the bottom of the tube, the normals do not respect the direction anymore and they point outwards. How can I fix this so that it respects the direction and angle of the geometry.... I will attach my file and some photos to show you what i mean. Also if you open up my file you will see on the side that I was also trying to rebuild each circle from scratch so that I can subtract them to get a Normal but I don't know how to bridge them together to create geometry... Thank you. normal_along_geo.hipnc

ahh . didnt realize it created a new name . thank you.

@FlorianEggers Thank you ! that works. I noticed there is actually a sop called "glue cluster" that does the exact same that i was doing in the wrangle. It seems to set the attribute correctly but it does not actually work in dops. Is there a way to get this node to work properly ? forces_question2.hipnc

Hello all, I am trying to go a little more in depth with the rbd force nodes in houdini. I am working with the magnet force in particular. I have a constraint network with random constraints set to a strength of -1 which means it will never break. However, when I use the magnet force on this constraint network it breaks everything and does not respect the strength of -1. Why is this ? How can I use the magnet force to respect the attributes I set to the constraints? I will attach my scene file for anyone that wants to take a look. Thank you forces_question.hipnc

never mind i think i got it

oops, i accidently sent that with out finishing... So that if statement does not work...am i doing something wrong with the syntax?

hello, I am trying to write an if statement with a fit function inside a scatter sop. Basally I want to gradually decrease points over time after a certain frame. I got the fit to work so that it gradually decreases over time : fit($F, 1, 10, 14, 0) So this scatters 14 points and decreases over 10 frames.I got that... now I want to be able to specify when the scatter starts if($F>50,fit($F, 1, 10, 14, 0), 0)

Hello , I am learning crowds in houdini and I have just figured out transitioning... However something is not working. I want to transition into a state when the agent is inside the bounding box and STAY in that state even when it leaves the bounding box... What is happening is that it switches to the state I want inside....but then it automatically repeats to the other states that I have set up initially. Is there a way where I can switch to a certain state inside the bounding box and keep it in that state the whole time ?? I will attach my scene file for anyone that wants to see. Thank you crowd_transition_bounding.hipnc

works great thank you !

Hello, I am trying to get the "bullet_add_impact" attribute to work . I need to record the impact data of each packed object so that I can isolate it after I import . In the help files for the rbd packed object it has a list of attributes houdini recognizes in dops and one of them is the "bullet_add_impact". It says : When enabled, any impacts that occur during the simulation will be recorded in the Impacts or Feedback data. Enabling this option may cause the simulation time and memory usage to increase. However, when I initialize this attribute in sops . it still does not create any impact attributes when I import ... Am I doing something wrong? Maybe I have to import it in another way?? I will attach my scene file for anyone that wants to take a look. Thank you. Impact_recording_Packed_Obj.hipnc

Hello, I am working with mocap biped two in Houdini 16.5. I object merged the mocap biped geometry from obj level into sops so that i can manipulate it. I am trying to get scatter particles on the geo and inherit the color from the material... However this does not work since there is no Cd attribute only a material_shoppath attribute....so my question is how do I turn the material_shoppath attribute into a Cd attribute so that i can use it normally ? Thank you
