  1. attrib sop is VEX aswell i dont think you can do it with an expression in transform sop because it does not run over each point like a wrangle but over the whole geometry at once.
  2. use a point wrangle @P.y = @ptnum; @P.z = @P.y;
  3. Well the scene with that arm is 100 times bigger than your test scene with the sphere. that's why all those values for volumes etc don't work. have a look at the attached file (I did not scale it down, but I recommend you do, right after the alembic node) and jump to frame 1680, let it cook and see if the result is kinda what you're after. Also I would go with a pyro sim with those points as source instead of those SOPs. Disintergration_hand_003.hipnc
  4. I had the same problem as sandford, so I wasn't even sure what to look for. So thanks for the new files. I'll have a look at it tonight if it hasn't been solved till then.
  5. what kind of errors? on what nodes? there shouldn't be any errors. did you update the file paths?
  6. don't know if that is what you need but you might wanna have a look at it Cheers Disintergration_hand_002.hipnc
  7. put this point wrangle just before the extrude: int neighs = neighbourcount(0, @ptnum); if(neighs < 3) { removepoint(0, @ptnum); } deletes the points (procedurally) so you get clean geo but doesnt fix the rendering issue. This comes from cusping the polygons. Do you need to cusp them? EDIT: fixing the geo with fuse nodes helps. see file SphereBoole_EdgeProblem_v2.hipnc
  8. it's because you have a lot of "useless" edges on the seam. delete them and it should work
  9. why don't you use your up-vector instead of @N? if I got this right, p@rot = quaternion(@Time, v@up); in your attribwrangle_INSTANCE should do the trick and remove those other lines
  10. it's quite easy. you need to make the 'gas resize fluid dynamic' track your moving source. have a look at the attached file Cheers dm_animatedFluidSource.hip
  11. here you go. I put some comments in the file. Cheers Edit: sorry I switched boxes and balls just switch them in my file and adjust sizes (box to 1.5, sphere radius to 1) dm_RBDswitchToActiveState.hip
  12. maybe try the op:/full/path/to/node syntax. maybe you have to add backticks `` not sure right now
  13. don't know, maybe you forgot to specifiy a distance on polyextrude or maybe it is because the wrange in your picture is set to points instead of prims anyway you might wanna have a look at my file and compare it with yours Cheers dm_extrude.hip
  14. so this new version has a customizable falloff ramp and sorta uses the seams of a boolean. I have no idea if it's possible to really define arbitrary shapes as boundaries.. I'm sure there is a way but I just have no idea regarding your last question: on attribtransfer you could set the blend with (that would be your range) and feed that into a spline ramp to remap the values to your liking Cheers dm_regionDisplace_v02.hip
  15. maybe something in this direction? ok, there is no definable distance and so on yet but maybe it's a start Cheers dm_regionDisplace.hip
