Hi, I haven’t used particle systems much and until recently never in a system where I needed such strict control over the rotation of the particles.
The current situation I’m in is to make a sesame seed hamburger bun. The seeds are a separate object which I am using in a ‘hair’ particle system on the bun. The problem is that the rotation of the seeds appear to be inconsistent across the surface of the curved bun shape with the particles closer to the edge standing up on more on the tip of the seed and the particles closer to the center dipping into the object such that I can’t see them. By tip I mean the location of the object origin on the seed object.
What I would like is to have the side of the seed laying flat against the normal of the object where it rests consistently across the entire surface as you would see on an actual bun. Additionally, I would like to be able to enable randomized rotation to get more realism without affecting the axis that would alter the way it lays on the surface (so only rotating around it’s normal, basically). I’ve tried fiddling with the position of the vertices in edit mode in relation to the object origin… placing it in the center, rotating it in different directions around it… unfortunately, nothing gets it right… it always seems like I can get some distance from the center perfectly flat, but everything further is sticking up from the tip and everything closer has the tip dipping into the object.
Does anyone with more experience have some tips?
I can post screenshots if needed.
