Hello everybody.
I haven’t been there for a while … I have a problem with a job I’m doing and you can probably help me.
Basically I have to create triangular-based pyramids (cones with three subdivisions) “implanted in an icospera” (therefore upside down).
With Geometry Nodes I instantiated the pyramids on the faces of the icosphere and then I aligned them with respect to the normal ones. The problem is that the triangles that make up the base have a standard rotation and do not touch edge by edge.
The reason is that later, some of these pyramids will have to rise above the normal ones and once they are far away, scale slightly and rotate around their own pivot point.
So the questions would be:
- How do I rotate the instances so that all the triangles have their sides aligned with the others? (mimicking the underlying icosphere?)
- How do I make instances move along their Z axis (perhaps using a noise texture)? I tried, but the system works for the scale but in the case of the position I don’t get what I want.
- How can I once these move away from the central sphere to scale them and above all rotate them randomly?
I’ve also attached the file I created to make things easier if you’d like to help me out 
I uploaded the file to weTransfer, I discovered that Pasteall is unfortunately dead =(
Thank you very much for the help you will probably be able to give me!
=)
