  1. UV on FLIP using Rest

    I know this question has been asked on here a few times but I still cannot seem to get a straight answer. I watched the 16.5 FLIP masterclass on how to use the dual rest solver but the thing is Jeff Wagner never actually got it working. If you open his scene files and disable/enable the VOP node you can see he actually didn't do anything- it's the same UV result either way coming from the UV Quickshade. Then I tried to read up on the Dual Rest and Dual Rest Solver nodes, to which there is essentially no explanation in the Houdini help. And while I understand the concept of the Rest SOP measuring the distance between initial positions and deformed positions on points, I still don't understand how to translate that into UV space. So I want to just put this to bed by asking a straightforward question and hopefully receiving a straight answer! (Please no links to other threads I literally have been down a rabbit hole on this several times with no good answers). I want to take the rubber toy test geometry, add it to flip with simple fluid source and FLIP object, use gravity to smash it against a floor plane. Outputting dual rest attributes from the flip solver. In this scenario, how can I- a - take the initial UVs from the geometry and have them deform with the sim b - take the dual rest attribs and use those to UV on my own with a procedural texture
  2. Hi, brand spankin' new to COPS, can anyone tell me how I could quickly generate a simple gradient ramp? I know how to get the COP onto my texture, just not sure how to generate the actual gradient. Thanks!
  3. Set Initial State For Vellum Hair?

    Vellum drape worked perfectly here- nice and simple solution. Thanks!
  4. Helloooo just trying to make it so my hair doesn't have to fall into place every time i start the sim. Thanks!
  5. Tried to open this today and now it magically crashes every time Teeth_Leak_5.hiplc
  6. Attach Hair To Animated Geo

    Ah beautiful, I had been doing that separately at first but it wasn't following the animation. The trick is to do Guide Deform and then pin the points. Thanks so much!
  7. Hi I'm trying in this setup with the Guide Deform SOP but as you can see it really is not working. Please help! Hair Fallout.hiplc
  8. Restore Deleted Shelf Tab?

    It was still there, just wouldn't load. I reinstalled RS and Houdini and it worked. Still... seems like there should be a way to fix this more easily, or load shelfs from another computer, etc.
  9. I accidentally deleted the Redshift shelf tab instead of closing it. How can I restore it? There doesn't seem to be a way to load a shelf file from disk
  10. Controlling FLIP Emission

    Figured it out, just had to clear out the SOP Path in the FLIP Object
  11. Controlling FLIP Emission

    Hello, I'm just experimenting with FLIP fluids for the first time and was wondering- is there any way to prevent the initial "glob" of liquid that emits on the first frame? Ideally I'd like the emission to start at nothing and then gradually build into a thicker stream. When I uncheck "Create Particles" in the FLIP Source node it removes the particles from the node, but has no effect on the sim.
  12. I'm using a POP VOP to add some noise to my vellum geometry, but it keeps sticking to other geometry when it collides. I assume this is because the geometry is displacing before Vellum can catch it, and by the time it does it's already intersecting. How can I make this work correctly?
  13. Copy To Points/Normals

    Yes! Ah I was so close I just couldn't figure out how to reference the point I was creating. Thanks!
  14. Hi this is pretty simple and I feel like I used to know the answer but it has escaped me. Here's what I'm doing- I made a box, then I created points at the center of each primitive using a wrangle, then I'm using Copy To Points with another box (so there's a "clone" in the center of each primitive of the original box) works great, HOWEVER, I can't figure out how to retain the original Normal when I create the new points to clone onto, so my clones aren't rotated properly. Please help me learn this once and for all. If there's a simple function I could call within the Wrangle that would be perfect. Thank you!
