  1. Vector not inverting when hitting surface

    I'd say it's because it's a function that is only available in shading context. I'm not sure exactly how is this structured, but I know some functions only works for shading, I'd be interesting to know why. https://www.sidefx.com/docs/houdini/vex/functions/index.html
  2. Mist-Ground Dust Effect

    create various smoke caches and place them by hand
  3. Rendering Cola

    I tried using nested dielectrics and absorption. if you force specular of air bubbles you would get those sharp highlights as well. You should increase a bit the render quality maybe, I'm on a laptop. nested.hipnc
  4. you could object merge different stages of your network in other geometries and link those to different viewports. but you can't set 2 distinct display flag in the same network.
  5. Houdini 18 Wishlist

    -something to simulate feathers, leaves, scales, fast and efficently. Vellum is helping a bit but is struggling a lot with rigid pieces and collisions. needs too many iterations to converge.
  6. you have normalize(@ptnum - p0) @ptnum is the integer id of the point, not its position.
  7. Vellum Super Rigid Constraints

    http://www.sidefx.com/docs/houdini/dyno/plasticity.html Note It is difficult to make very stiff material in Vellum, such as sheet metal. For very hard materials, use Bullet Soft Constraints.
  8. from time to time i have that problem, I've been burned once and now I don't really trust the spreadsheet's order I always order by another column to force a refresh and have it working correctly again. if you managed to make it reproducible maybe is a good idea to send it to sidefx so they can take a look.
  9. Houdini grooming tools parting lines

    i tried to put the parting lines in the guide groom, (and create a rest sop or it will complain later) and it seems that the hair gen picks it up and part it correctly.
  10. Fusion vs Nuke

    because what applies to you doesn't necessarily apply to everyone else. If cops is enough for your work that's great, someone else might have different needs. (Rotoscoping, tracking, speed.. )
  11. Dense cloud shader (wdas cloud hype)

    to get dark edges you need to use forward scatter in the shader and many bounces of light. even with 8 bounces you can see the effect of dark edges. the more the bounces the brighter it gets because it more likely that the ray bounces back into your eye. From what I can see the math is already there and working, but is a bit slow. Does redshift support multiple volume bounces? is it capable to simulate internal volume scattering?
  12. Intersect VOP gives the coords on a surface, reading the help it seems to me more like dot(a,b)/length(b) https://en.wikipedia.org/wiki/Dot_product wiki calls it "Scalar projection" Never used softimage tho.
  13. local minimum in 3d

    I would say is the laplace operator https://www.khanacademy.org/math/multivariable-calculus/multivariable-derivatives/laplacian/v/laplacian-intuition
  14. Alembic geo not working with Boolean

    have you unpacked the geo and converted to polygons?
  15. Strange VDB bounding box rendering

    have you checked the background value?
