  1. Thank you so much for your answer! Houdini is such a beast of a software. I really want to grasp the basics before diving into more complicated stuff.
  2. So it seems like even if you create a point, it's not created until the end of your code (output of wrangle). Because if I try to access it's position in a detail wrangle, but in another one, it works. If I do it in the same node as it was created, it returns false. So if I need to move my geo, but inside my detail wrangle. Do I just end my code in detail wrangle, add a point wrangle, then add another detail wrangle? EX: I want to create geometry, then move it to (0, 0, 0) to do some trigonometry and create prims and points etc..., then move it to it's previous location. Do I have create 4 nodes? Or is there a way to do it all inside the detail wrangle? Maybe I just need to adapt my code. Thanks!
  3. Hi, my title may be confusing, but it's a noob question. I'm having trouble accessing points attributes in detail mode. I can create points easily, but when I want to access let's say it's position, it always returns 0,0,0 with the point() function. Also it seems that points created AND removed still appear in detail attributes but not in my points. I'm not sure I completely understant the logic of detail vs point(...) and it's relation/interactions. I have attahched a file containing both examples of my problem noobQuestion.hipnc
  4. Ramp Parameter node returning 0

    Okay I found out that if I change the name, the ramp will update and work... So everytime I make a change to the spline ramp, I need to change the name of the node. If I don't, nothing happens. Is it supposed to work like that? Edit: After a little bit of troubleshooting, I found out that in order for it to work, you need to get out of the attribute VOP node, and change the ramp in that node parameters instead.
  5. Hi, I'm following this tutorial: https://www.sidefx.com/tutorials/vops-vex-and-ramps/?collection=66 Around 22:30, he uses a ramp parameters node inside an attribute VOP. The problem ofr me, is that my ramp always returns 0. I have set it as a spline ramp (float), converted it to a vector 3 (plugging the same output in all 3 values). Also, the color of the connection is not the same as the output "circle". Edit: Well i'm an idiot. It's not the same color because the node is selected... However the other problem still persist. Here is the file: SideFX_Tutorials2.hipnc Is this a bug or i'm doing something wrong? I'm using 18.5 Thanks!
  6. Select only concave edges

    Thanks everyone. I checked all solutions and it's exactly what i'm looking for. @Noobini Sorry, will do next time. First time here and I didn't know sharing files was the norm here. Thanks!
  7. Select only concave edges

    Hi! I would like to select only concave edges (green edges on picture). Let's say I have a cube, with a small extrusion on one face. I know I can select edges by angle, but it selects concave AND convex edges. Any idea how to do it procedurally? Thanks!
