Converting 7905 leaf help with ring segments please. - Peter Grass - 2026-01-03

I've started converting over the new 7905 leaf part into something that can go on the tracker.

Is there a better ring segment I can use for the back half of rounded portion of the leaf so it looks better in high res? I don't really get which one to use other than the half rings and you aren't supposed to rotate other ones other than by 90 degrees.

Not complete sure if I got it right, but shouldn't a 1-8ring do the trick?
The remaining gap to the leaf would be 7-11 degrees, which typically works fine enough without prims.

EDIT:
Merging the 2-4ring and the two 1-8ring into two 3-8ring would be even better structure wise I think.

3-8 prims is indeed the obvious choice here...

Not needed here, but you can of course do that if there is no other solution! Just keep enough precision (4 or 5 decimal points) in the transformation matrix to avoid too large mismatches.

Other considerations for this part:
- Rotate it 90° to match the orientation of similar leaves, eg. 3565
- Part is symmetrical, make 2 half subparts
- Using 2 rings on top to go from R6 to R10 is fine, but using ndis+chrd+quads avoid the introduction of needless vertices. Here is how I would do it:

Thanks very much for the help Chris & Philippe that looks a million times better.
