Thank you Follyx. That's inspired.

Hi, guys, It's a very simple scene. A torus emit particle fluid into a box . (fig.0) I cached a compressed flip fluid , and retime(speed=0.6) it , the particle fluid surface node will not return a correct result while the "Union Compressed fluid surface" checked. It seems like the compressed fluid surface is not at the correct location and make a very strange result (fig.3). The retimed particle looks ok ,but the mesh not. fig.1 is particle, it's correct , fig.2 is compressed fluid surface, it seems not at the correct location, fig.3 is surface polygon soup. There is a very strange artifact. Is there a way to retime compressed fluid? Thanks!

Thank U very much. It works.

Good idea!Thank U very much!It works.

Hi,guys! Is there a way to exchange two points' @ptnum? I want to exchange pt0 and pt1's @ptnum.And don't affect the prim Normal direction. setpointattrib(0,"ptnum",0,1,"set"); setpointattrib(0,"ptnum",1,0,"set"); They don't work. Thanks.

Thank you .Yes,this will need high resolution mesh.although attribfrommap is much more efficient than pic function.It is inspiring.Thanks again.

Hi, I want to emit particles from an texture just like in maya. I find the old thread here : but in houdini 16.5. That seems not work. . there are no " birth probability ",but "emisson attribute".And it says that it will use a point attribute.(but this will need very high mesh resolusion.) I fill the pic function in it ,but it returns an error. How to do this ? Thank you very much.

It is great! Thank you very much!

There are points of a grid , grouped by bounding geometry. The sphere1 is moving, I want to save the time ($FF) to a point attribute,when the point was joined to the group. How to do that?Thank you very much!
