Hi Tesan, As you said, I tried "Multi-Snapping", instead of "Grid Snapping", and it works fine. Thanks.

Any idea?

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.

Thank you.

Any idea?

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

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

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.

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

Hi guys, I found this helpful document on the SideFX help page: https://www.sidefx.com/docs/houdini/grains/stablepile.html

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.

I know I can use the "Awake node", but how can I make the grain pile harder to collapse, without using "Awake"?

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

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