  1. Hi everyone. I cannot find any information on how to get an attributes created during the previous iteration within For Loop with Feedback? One of the dilemma why when Single Pass is on and Pass is 1+n, I cannot see attributes created on points from previous iteration? I use Fetch Feedback as a data for previous operations. And Fetch Point as a single point extraction around which I want to perform operations on the current pass. I tried to extract the number of the current iteration with Metadata node and find ptnum based on it, but without success. So I use Fetch Point for that. I wanna to pass attributes from current itteration to the next one. And read preaviously created attributes in current pass. So the the attributes would interact throut itterations. I add test file. 4loop_ftb_test.hipnc Any tips or tricks? 4loop_ftb_test.hipnc
  2. Hi guys. I have a problem with one of my HDA's. I have 3 parallel loops. The first one is looking for a number of iterations to run out of points and stop by triggering Stop Condition. The second and Third loop is using a number of iterations from the first loop. Problem is that the first loop does not update when HDA is inside a loop. I have to select the first loop output and then it works. UPDATE: I thought that the problem is that the first loop is parallel to the one dependent on it, but after I added it to the flow and it is before the 2 others it is still not updating. Any way out?
  3. Hello, i trying to do something simple but i am knid of new to houdini so i dont know the tricks yet. i have a float number in a for loop that i want to divide by two every iteration. What is the appropriate expression for that?
  4. hi Do you know how to keyframe each iteration inside for loop block? Currently, $F in "Iteration" parameter reevaluates everything. Or is there a way to keyframe "next "iteration?
  5. Hi guys, is it possible to get an attribute value from loop before current in foreach loop?
  6. Hello! In Attribute Wrangle I did: vector x = {1,2,3}; int i = 1; vector y = set(x1); // this makes @y={1,2,3} Can I did it in other way to get the same result?: vector y = set(x); // here x should became x1
  7. Hi everyone, trying to figure out how to randomise the number of iterations of a pc open in a vop node, based on a per point random the goal is to make variation in the speed of the propagation. I join a simple file, if somebody can help me it would be really apreciated Thx by advance Cheers basic-propa.hip
