| Oct 20, 2019 at 13:35 | comment | added | Robert Gützkow | @ToddMcIntosh I've updated my answer, it now includes an add-on. You can enable Local Axis and rotate the cone object in order to adjust the axis. Instead of sending me the offered money, please consider donating it to one of the listed organisations. | |

| Oct 20, 2019 at 0:59 | comment | added | Todd McIntosh | As a bonus question, if I wanted to have the ability to bias the rotation of the cones towards the global Z axis by a small amount (say 0-15 degrees), what would be the additional code to do that? I'm currently doing it with a Copy Rotation constraint on each cone object that references an empty above the sphere, but I'm sure there's a cleaner way of doing it in code. | |
| Oct 20, 2019 at 0:57 | comment | added | Todd McIntosh | Ok, after testing it out, this definitely was the answer! In addition to your changes, I also had to change the line PlaceParticle(emitter, src_obj, adjPoints) to PlaceParticle(emitter, src_obj, p) as I was incorrectly multiplying p by the emitter.world_matrix value. After both changes, the script works great! Thanks. Please send your paypal email address and I'll send the bounty. | |
| Oct 20, 2019 at 0:33 | comment | added | Todd McIntosh | Also, I didn't mention that in the file, the origin point of the cones is at the tip, so I would use Z instead of -Z in the surfaceNormal.to_track_quat call as I am doing. | |
