  1. Hello again! I have a simple IF condition here that fetches an attribute value from a geometry & prints a result according to the comparison but for some reason it's not behaving as expected. It's just 2 nodes & very simple yet as a non-programmer I'm scratching my head. If anyone can take a look & tell me what I did wrong I'd really appreciate it If_condition.hipnc
  2. i have a model with 2000 pieces , some of them need to use polyfill and some of them need to use polyextrude. the problem is i cant find a way to make a condition to seperating them. the correct result should be like this (pic_1) : when they only use polyextude (pic_2) : and when the only use polyfill (pic_3) : i want to make a condition for change switch node to use correct sop for each object. is there any solution to fix this situation ? thanks alot Condition_problem.hipnc
  3. Condision in SOP ?

    is there any solution for make a condition in sop level ? for example i have a loop (based on connectivity) and inside that i want to add pollycap on only objects which have unshared edge. is this possible to do it in houdini sop ? thanks
  4. As I understand it, stylesheets give you the opportunity to have multiple conditions per override. I have basically organised my stylesheet with a material per override and then I add in the material assignments per geometry with conditions. However, I have geometry that drops out and renders default grey if I have multiple conditions on the same override. Does that sound familiar? Am I doing stylesheets wrong?
  5. Like many, I'm new to Houdini. I am using a single file to try to make some practical use of the application while I try new techniques. I've attached my file. Here is are the things I can't seem to figure out in general, in order of difficulties. Passing velocities to DOPS from SOPS? - I'm trying to fracture geometry which i can do, but I want to only allow the Voronoi node to turn on when a velocity is at a certain threshold. In my Geometry Spreadsheet it is showing velocity of 0. I've tried many things and can't seem to give it velocity. Variance - I'm trying to give the gravity node (or any node) a variance of force. Gravity is ~ -9.8, but I want to do something like maybe "between -9.8 and -15." I've also tried things such as "fit" or "rand" but it didn't seem to work. Lastly, this isn't so much conditions in general that I'm confused about. But one thing I like to do is kill particles in other applications when they are out of view of the camera. So in my file, I'm trying to kill the DOPS fractures and soon to be POPS when they go below "number" in the Y axis. I added a delete node and tried "if(@P.y< -1, 1, 0)" in the DOP network, but I don't think I'm using it the way I should...Just to tag along onto this one too, since POPS and DOPS are now unified, how would I go about applying the same kill/death technique to POPS too? I appreciate the help as I'm still learning. I attached my file to tear part if needed. Thanks ! Best, Stark noise_start.hipnc
