  1. Can't remove duplicate edges/surfaces

    Hey, I'm trying to create a honeycomb pattern using SWEEP on NURBS curves. My problem is that the pattern of my curve overlaps so when I use sweep there are duplicate surfaces. I have tried using FUSE, CLEAN, POLYDOC before and after the sweep, but I cant seem to clean it up. Thanks! geo hex.hip
  2. Hey, I'm having trouble shading volumes created with the pyro solver in houdini 18. I have created a custom volume shader which seems to work fine with with regular volumes however I can't seem to get color when the volume is created with a pyro sim. Both volumes output density as a volume which is what I am using to drive the color in the shader, i have attached HIP file. Thanks! Volume Test.hip
  3. Random color to instanced objects (Stars)

    Thanks so much Vitor! At least I know my approach is correct. I think my issue is with the fact that i'm using a volume shader on the instanced volume which does not seem to be picking up the inherited Cd? I tried refreshing the viewport but it does not seem to work. I have attached the .hip file. Thanks! stars example.hip
  4. Hey Guys, I'm very new to Houdini so this is likely a basic question. I'm trying to create a background of stars for an eventual nebula scene and I'm having trouble randomizing the color on my instanced stars and am not sure if I am approaching the problem correctly. I have created a sphere and converted to fog VDB using 'VDB from Polygons' --> this is my basic star shape. I have then instanced it onto points scattered onto very large spheres which encompass my scene, for this I used 'copy to points'. By using an attributevop I was able to randomize the pscale of my points and this was successfully inherited by my instanced objects, however I have not been able to do the same with Cd. I have tried playing with Cd in attributevops and volumevops as well as trying to use Cd in my material shaders for the volume color (I am using pyro shader and have also tried volumeshader as well). If you guys could point me in the right direction it would be very appreciated! I'm also curious about other methods you guys have used to create stars in houdini if you feel like sharing!
