I've redone the tutorial for the third time and the problem has persisted. However, I think the issue is the "No group output attributes connected" error that shows up below the Geometry Nodes modifier. When trying to apply weight paint to the object surface (The "Icing") there is no option to alter the density to that of the weight paint, I assume because there is no assigned group. How do I solve this issue? So far I've tried: recreating the sprinkle, setting the sprinkle's origin to geometry, and assigning the sprinkle to the icing by list and by dragging the object from the menu into the geometry node work area.
While I'm still not sure why this issue is occurring, by redoing the tutorial from the start and then by setting the cylinder's origin I now have more than one sprinkle! I just turned my density up to 800,000 for now, until I can figure out why this is happening.
I followed the advice of the answer and have redone this part of the tutorial, which has improved my results! So thank you very much! But I'm still encountering the same problem, just with marginal success. I now have a handful of sprinkles if I turn my density up to 50000, but it isn't nearly what I need.
I'm following the Blender Guru donut tutorial for 3.0 and I 'm having issues on Part 9 - Geometry Nodes. And the first issue begins when I attempt to add the Distribute Points On Faces node to my geometry nodes.
In the tutorial, adding the Distribute Points on Faces node causes large, sharp geometry nodes to appear on the object. My object disappears when I add this node. I decided to keep going in the tutorial, although I think this is the root of the problem. The next step in the tutorial is to add the Join Geometry node, which I do and this brings my object back into view.
After that the tutorial had us model the object that was going to become instances on the base object. We did this by adding the Instances on Points node and then dragging the object that will become the nodes (in my case a cylinder named "Sprinkle") into the Geometry Nodes work area, so we can use its shape.
Then I was supposed to get the geometry of the "Sprinkle" to be the node on the base object, but even when I linked these nodes it didn't appear. I upped the Density to 100 and the seed count from -50 to 300, but nothing appeared. So I looked for a solution and found that I should apply the scale of my node object (the "Sprinkle") to get it to appear. I tried this next.
However, as you can see, nothing happened. But I figured out that I can cause one sprinkle to show up if I put the Density between 300-800 and the Seed Count to 1. Anything outside these parameters and it either doesn't react or the single "Sprinkle" vanishes.
What went wrong and why? I'm very new to Geometry Nodes.
