  1. particle streams - point id

    sorry I did not see your post until now. Yeah that should be doable in sops as well. If you are emitting from points in your popnet, you could have a chance value on each point that you are emitting from, and based on if that chance is true or false add that to a group. so if the chance is 1 that point goes into one group and if its 0 it goes into another group. if you want to create it after your pop simulation, the first thing that comes to mind is run your points through a sop solver, , and when age < value assign it either one group or another based on a chance percentage. then everyframe check which group attrib it had in previous frame and maintain that value. there is probably simpler solution but this was the first thing that came up
  2. Spiral Gas Target Force?

    you could maybe apply some of these principles?
  3. Control Where Points Scatter

    paint a density map and scatter only by density
  4. particle streams - point id

    create pop groups. one group for you mainstream with no spheres instanced. another group with 1% the amount of particles, and instance spheres onto that group only.
  5. remember you need to set the bind node to string.
  6. I am not sure if the uvquickshade is something that can run over each primitive, and I am not the best with Hscript (which is what you need for your string to work) however the workaround for this could be as follows: in primwrangle: s@texture = "yourpath."+itoa(prim(0,"class",@primnum))+".jpg"; then in a primvop put down a texture node, and connect uv from global to uv on texture node. put down a bind and import the attribute "texture" pipe the bind node into the map slot on the texture node.
  7. Random link of interest

    there is your next challenge Noobini. extra points if you turn it into an OTL
  8. Change Orientation for Points

    use the popLookAt node. This operator modifies the orient, torque, targetw, and spinresist attributes.
  9. Circles between two curves

    how about this: -resample the curves to have equal amount of points. - measure the distance between the points with the same point number, this will give you the diameter for each circle. - you can now place a point using the radius and instance a circle onto this point.
  10. POP Replicate not working

    under the Stream tab on your popreplicate you just input "source_first_input1" which is the name of the stream your create from the popsource, then it will work. if you dont want your particles to inherit the original age from your source stream change the * to v in the inherit attributes under the Attributes tab on your pop replicate
  11. Still cooking a pyro after loading bgeo from disk

    have you checked the performance monitor? you can record a change in frames and see which nodes takes the longest time to cook. Also in your network view under the View tab enable the "show if nodes are time dependent". This will give you a little clock icon on the nodes that needs to cook.
  12. if you can share a hipfile it would be a little easier to troubleshoot.
  13. Fixing Normals

    awesome man. Feel free to share progress
  14. Fixing Normals

    there is two things you need to do: - in your polyframe node untick tangent and tick Bitangent and set that to N - in your transform node called "flatten" put 90 in rotate.x so that your geo is pointing along Z axis cool model
  15. Pack primitive after for looping has different pack points

    any chance you can share the file?
