I'm working on a vines field and I want to use geometry node to instanced a collection of vine trees following a curve. I'm using Blender 2.93 so I converted my bezier spline to a mesh and used it with a Point Instance and now I need to orient each vine to the next one as a "curve follow" does. How can I do that? Please help!
$\begingroup$ Can you please explain a bit more? In the screenshot, you already have instanced vines on the edge. Can you please elaborate on what you want to do $\endgroup$– Maulik SharmaJun 25, 2021 at 9:43
$\begingroup$ I juste want to orient the instanced objects following the green arrows in the screenshot by calculating the z angle from the current point to the next one. Sorry I hope I am clear. $\endgroup$– Simon SalordJun 25, 2021 at 9:46
$\begingroup$ Can You share the blend file? It will make things a lot easier. Just upload it to pasteall.org/blend and share the link. $\endgroup$– Maulik SharmaJun 25, 2021 at 9:47
$\begingroup$ I don't think that sharing the blend file could help because there is nothing more than it seen in the screenshot. The vines are pruned according to a very specific mode and there remains only one branch that must be attached to a thread that connects each tree. So these branches must point in a direction following the wire (here the curve) $\endgroup$– Simon SalordJun 25, 2021 at 10:16
$\begingroup$ Don't think it is possible in 2.93 unfortunately $\endgroup$– GorgiousJun 25, 2021 at 12:14
This can be easily solved with Blender 3+.
Either you do it like here in the screenshot:
...or you calculate the direction vector for your rotation by yourself using the points: Instance Objects on a Line Mesh or Spline
