  1. Python, Get current node

    Ah, ha, that makes sense now. Just tried it out and works perfectly, thank you for the answer, I appreciate it!
  2. Python, Get current node

    Using python, how can I get my current node. Not the selected node, but the node that I'm currently in. In my search I keep coming across hou.pwd(), but that always just returns / whenever I try it. I figured out how to get the parent of a selected node, but that doesn't work if you don't have anything selected. Thanks for any help!
  3. Hi all, does anyone know a good way to average an attribute such as Cd over time? Meaning, it would something along the lines of this - on a particular frame it would average the current frame with the one before and one after? I have a lot jittering in my Cd from one frame to next and I'm looking for a way to smooth that out. Thanks!
  4. Wire Solver Wind

    I'll post what I've figured out so far in case it is helpful for anyone else - I lowered my scale force from the default of 100 to .1 (not sure why I needed something so much lower than default but that's what seems to be working for now). Second, I played with the values for Turbulence and Roughness under the Noise tab. I'm starting to get some some gentle ambient movement through the wires which is roughly what I was shooting for.
  5. Wire Solver Wind

    Hello all, does anyone have any tips on applying nice looking ambient wind to wire objects? I have several wires constrained together in a way that is working well, but I'm having a hard time getting any good looking wind to give them ambient movement. I've tried the wind force several times, but can't seem to figure out how to get good results from it. Thanks!
  6. Thickness mask to @Cd

    Thanks! - I did find a rather hacky way of doing this using the ray sop, but I think using intersect_all will be faster and more flexible.
  7. Houdini noob myself, so take this with a grain of salt - but there is a "Timescale" parameter on the flip solver that can be changed according to your needs (seems to work as I'd expect, as I've been messing with it lately). There is also a "Time Warp" sop although I don't expect that would work well with a fluid mesh. Hope that helps!
  8. Hello all, I'm trying to find a way to create a thickness mask - I'd like to use it on a mesh surface to generate a faked subsurface look. My general idea is that I would fire a ray from the camera position to each point of the mesh, then measure the distance to the next surface each ray hits. I'm sure you could then fit range that, and store it in @Cd or a custom float attribute. Does anyone have any hints on how to go about that (or maybe there is already a prebuilt method of doing so?). Thanks!
  9. Float into vector (basic)

    Thanks to both of you.
  10. Float into vector (basic)

    I know this must be pretty basic, but for some reason, I can't figure out how to do this. I'd like to be able to alter one of the values of a vector using a float variable, like this: float dist = length(@P); v@force = {0, dist, 0}; To me, this seems like it should work, but always returns a syntax error. Any tips? Thanks!
