  1. Delete SOP making particles go crazy

    Delete by id instead of point number.
  2. Move points through the "center" of a SDF

    This could be improved upon but it works for this case (mostly, the intersecting tubes are a problem): volume_to_particle_dv.hip
  3. boolean vs post cleanup

    If it works then its fine. If you do the UVs before the boolean that should work fine too.
  4. Learning Curve of Popular 3D Software

    Kinda depends doesnt it? If you know zero about any 3d application, I guess the learning curves is similar. Might even be easier in Houdini because you know what happens at all times. However if you first learn the maya way of thinking, Houdini will be harder because you already have a different mindset - and vice versa. Learning new stuff isnt the hard part, changing what you already know is.
  5. Pyro Advect vector openCL bug

    It probably thinks it can skip the Cd.z because you have "Two Dimensional" turned on, so it will only "need" two dimensions even for a custom field. I dunno. If you uncheck that and limit the box manually to be 1 voxel thick it works.
  6. pyro cache gets stuck in place/ freezes

    Are you running it with OpenCL? That usually happens when the graphics card runs out of memory.
  7. Specify light color in Kelvin?

    If you open the color editor, there is a small icon that looks like a thermometer. Press that and you can type in the color temp.
  8. Houdini 17 Sneak Peak

    What does this one mean? Isn't pyro using them already?
  9. Houdini 17 Sneak Peak

    Well H16 was named Amarok and that means: "An amarok, or amaroq, is a gigantic wolf in Inuit mythology, said to stalk and devour any person foolish enough to hunt alone at night. Unlike wolves who hunt in packs, amaroks hunt alone." So apparantly they've just gone for mythical creatures in their naming, much like Apple was using names of cats before.
  10. There is two types of motion blur, transformation blur and deformation/velocity blur. Transformation blur is animation on obj level, while deformation/velocity happens in SOPs. So you can animate at the obj level, and then also have velocity blur in SOPs - to mix transformation and vel blur.
  11. Transfering colors in attribute wrangler

    Instead of this: setprimattrib(0,"Cd",add_prim,1); Do this: setprimattrib(0,"Cd",add_prim,@Cd);
  12. Just guessing here but isn't that kinda the same as just deleting the point, since a point cant exist without a position?
  13. Modulating Motion Blur

    Theres a parameter you can add on the Mantra ROP thats called something like ”shutter shape”. That gives you a ramp where you can say when the shutter is open or closed.
  14. "opinput:1" to operator full path

    Not sure how else to do it, but in a wrangle do " s@test = chs("test"); " and then you can use the expression " `opinputpath(".", 0)` " in the parameter.
  15. Yeah I agree, it would simplify things sometimes when you need N for something else.
