  1. You can drive a scatter SOP with any attribute and then plug that into the voronoi fracture node. You would need to transfer the colour values onto the geo first with an attribute from map node
  2. If you're working with packed objects you can set an active attribute on each objects in the SOP level. I wrote this expression in a Point Wrangle to randomise the activation: int randomF = ceil(fit01(rand(@ptnum), 1,30)); if(@Frame>=randomF){ i@active = 1; } ; Then under the rbdpackedobject1 node in the dopnet I checked "Overwrite attributes from SOPs" randomActivation.hipnc
  3. Had to give it a try bottlecap_SeanR.hipnc
  4. Hey Atom, I've dropped down an assemble sop to create a new name attribute then referenced that attribute in the delete sop. I've also added "-1" to include the first piece. Is that what you're after? ap_ts_fracture_inner_detail_ONLY_071817_fromSeanR.hipnc
  5. Do you just want a triangulated version of the original mesh? Try the remesh node.
  6. Try putting the solidembed node in between the object to be converted and the copy node
  7. You can connect either a box or a bounds sop to the for each and it should set the dimension automatically for you.
  8. Instead of using a the pointsfromvolumeSOP, try converting the mesh into a volume with either an IsoOffset or VDB from polygon node then use a scatter SOP and set the amount of points you want to use in the Force Total Count parameter.
  9. You can try adding velocity of the geometry and use that to drive the flip particles. I've attached a scene where i've set the velocity vectors to flow up and over the geometry using a cross product, then added it into the sim using point cloud nodes in a POP VOP. geoDrivenFluid.hipnc
  10. Hi James, I couldn't open your file for some reason. I've attached a quick and dirty example. I've used a remesh node to triangulate you mesh and a divide node set to Compute Dual to convert it into Hexagons. It needs some tweaking as the hexgons aren't a perfect grid, it may be worth looking into the scatter or points from volume nodes to create your triangulated mesh. Hexagonal Growth_SeanR.hipnc
  11. Hi Chris, On you're copy sop, do you have "Pack Geometry before copying" checked? That will make each copy packed object that you can bring into your dopnet with a RDB Packed Object node.
  12. Hey James, The easiest/most controllable way would be to make the shapes that you want the growth to create before you propagate it. So in your case you would want to make you mesh out of hexagonal faces, here's a link to a number of ways you can do this:
  13. Could be your Normals? Might be worth giving them a check.
  14. Hi Nick, You can do a volume sample to get the particles offset from the sdf, multiplying this with the volume gradient will give you a vector. Adding this vector to the particles position will move it onto the surface, the vector will have to be negated to work correctly. noodle_v4.hipnc
  15. Hey Rob, You need to check the Use VEX expression checkbox and type it into the textbox that appears.
