  1. I want the point to snap to the grid lines...

    Hi Tesan, As you said, I tried "Multi-Snapping", instead of "Grid Snapping", and it works fine. Thanks.
  2. Hi guys, How can I snap a point to the "grid lines"? When I use "Grid Snapping", it only snaps to the crossing points of the grid lines. Thanks for helping.
  3. Ripple Solver issue!

    Thank you.
  4. Ripple Solver issue!

    Any idea?
  5. Ripple Solver issue!

    Hi guys, I tried to use a "Ripple Solver" and everything is ok when I use it on a deforming grid object, but when I use a deforming tube, it doesn't work. How can I fix it? Thanks for helping. Ripple Solver_01.hip
  6. Hi guys. In a smoke simulation, I want to use a thin deforming geometry (a sheet) as the collision object, but instead of creating a Volume, I want to use "Point Velocity For Collisions". Is it possible? Thanks for helping. Smoke_CollisionPoints.hip
  7. Hi guys, I'm looking for some tutorial that helps me to understand DATA in the DOP network a bit more, in-depth. I mean something that helps me to work efficiently with dynamic nodes like: "Empty DATA", "Apply DATA", "Copy DATA", "Fetch DATA", "Modify DATA", and so on... Why they use this: " /obj/AutoDopNetwork : flipfluidobject / collision "? Is the "collision" one of the data and this is another way to grab it? Where can I find a list of several DOP DATA? I took a look at HDK on this page: https://www.sidefx.com/docs/hdk/_h_d_k__data_flow__d_o_p.html But I find it too complicated Thanks for helping.
  8. Hi guys, I need to find all points, near each point, in a certain radius. So I tried these codes: int np[] = nearpoints(0, @P, chf("Max_Radius")); i@NearPoints = len(np); Is there any simpler function for this situation? Thanks for helping. Find Near Points_01.hip
  9. How can I prevent the Grains from shrinking?

    Hi guys, I found this helpful document on the SideFX help page: https://www.sidefx.com/docs/houdini/grains/stablepile.html
  10. How can I prevent the Grains from shrinking?

    Hi Ultraman, Your "Point Separation " is very low resolution. If you change it from 0.1 to 0.01, then the grain shape will collapse.
  11. How can I prevent the Grains from shrinking?

    I know I can use the "Awake node", but how can I make the grain pile harder to collapse, without using "Awake"?
  12. How can I prevent the Grains from shrinking?

    Hi Ultraman, My simulation is based on the "POP Solver", so I can't use Vellum.

    Hello; Here is my scene. KeepShapeOfGrains.hip

    Thanks "Tesan" for the reply, but sorry I didn't get that
