  1. Alembic curves rendering - segmented ?

    on the /geo1 object, go to the Render tab/Geometry and turn on "Render Polygon Curves As Subdivision (Mantra)"
  2. Intestines/Guts with point relax

    have a look a this thread, that should help
  3. FLIP volume loss: water wheel

    Also don't expect FLIP to preserve volume, it just doesn't do that. The particles are added or removed based on the surface field - that's only a rough estimate and the volume loss becomes worse the more frames and/or substeps you have. This old masterclass explains some of the concepts of FLIP https://vimeo.com/15571778
  4. Easy way to animate material hue?

    there are 2 hscript functions: rbg() and hsv() if you open a textport, type: exhelp rgb

  6. attribute from volume

    this is what I get in the mantra render, I even downloaded the file from the forum just in case. check that the file : /tmp/volume.bgeo.sc exists on disk.
  7. Remap noise color

    you can extract the Hue of the colors with rgbtohsv and plug that float value into a ramp check the attached HIP cop_remap_color.hiplc
  8. Pyro sparse and colored smoke, how is this?

    To get color with the sparse pyro, you'll need to source/resize/advect. source : Volume source: add Cd resize : Advanced/Resizing/Extra Fields: Cd advect : Advanced/Advection/Extra Fields: Cd check the attached hip file sparse_pyro_color_01.hiplc
  9. attribute from volume

    I attached a simple example you'll need to write the volume to disk so Mantra can sample it at render time. volumesample.hiplc
  10. attribute from volume

    you can use "volumeSample"

  12. how to change HDA node color?

    node = hou.node('/obj/geo1/null1') node.setColor(hou.Color(1,0,0)) also you could have just googled: houdini set node color and clicked on the very first link
  13. I have it on 18.0.565, maybe you need to have the latest sidefx Labs installed?
  14. Javascript to Vex snippet

    what VEX code did you try?
  15. [SOLVED] Colored smoke turns dark

    in your volumerasterizeattributes3 node, set the voxel size to same as the other (0.05)
