    • Hi everyone,  I've never really dug into the Houdini crowd system in all it's glory, but I'm trying to do something that seems pretty typical. Currently I'm attempting to create a single agent that has multiple character skins that I can turn on and off in layers.  It seems simple enough, but 95% of the tutorials out there show you how to add rigid props ( swords, hats, etc ) to your character using an agent layer sop. I have multiple models that all have the exact same bone deform settings and they all work with the same rig. I feel like I"m almost there, but I can't seem to get it to work properly. I'm sharing a few images of my situation.  1. The first image has the output of my Agent sop. I'm reading in from a modified Character rig that works properly. The clips make him move fine.  2. Second image has my alternate model of the girl in T-Pose. All the bone deform attributes are there, so it should work fine.  3. In image three you can see the output from my agent layer sop. The model seems to be deforming properly, so the new mesh is now added to the shape library.  4. Shows the load clips section. She's posed correctly at the frame I'm at, but she won't move with the clips when i scrub the timeline. She's frozen.    Am I doing this properly? It would be incredibly helpful to see an example file for this that I can take a look at.                 
    • Is it possible to create and configure a rig that behaves this way: when moving point 1 down, point 2 and 3 will move so that the final position configuration will be that of image two? In essence having point 2 sliding on the line defined between 0-1?
    • Houdini's built-in Resample COP only does Stretch. If you want a letterboxed fit, a fill that crops to the canvas edge, or a tiled repeat with mirroring, you're chaining nodes and computing UV offsets by hand — and redoing that math every time a resolution changes. Scale COP is a free HDA that wraps the whole thing in one node. Pick a target resolution (preset, explicit, or pulled from a size-reference input), choose a fit mode, optionally tile, pick a filter. Done. No manual offset math. Fit modes: Distort, Fit (letterbox), Fill (crop to fill), Width, Height, None (1:1 pixel) Tile modes: None, Repeat, Mirror X, Mirror Y, Mirror Both (with UV offset) Filters: Point, Bilinear, Box, Bartlett, Catmull-Rom, Mitchell, B-Spline, Auto Size reference input: connect any upstream node to drive the output resolution automatically — no manual width/height entry when your canvas size changes Free download: https://github.com/kleer001/funkworks/releases/tag/scale_cop-v0.1.99 Houdini 20+, any edition. FX users: a build script is included so you can compile the HDA under your own license and avoid the Indie/Apprentice flag. First Houdini release from Funkworks — a small open-source collection of free DCC tools built from real workflow problems. Feedback and bug reports welcome!
