Card trick: guessing the suit if you see the remaining three cards (important is that you can't move or turn the cards). I don't have Blender in front of me right now but I believe you can align to the surface normal/face normal in geometry nodes. This makes it much more easier to align the rotation of instances to faces of a base object. Connect the Vector input of the node to Group Input, toggle the Input attribute from the Modifier properties. The second one will be used to rotate the local Z-axis of the cone instances towards the direction of the inputted normal vectors. Is it realistic for an actor to act in four movies in six months?

Why are the cones rotated like this? In the example images below the result is the same for all multiples of the vector (0,0,1). The align rotation to vector node was removed in the 3.0 alpha and I was wondering what the math was behind this node to achieve the same result in Geometry Nodes with fields. I believe the attribute is something like vertex_normal, for example. Graphics card: GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.89, Blender Version like the normal. Local axis of the object that is to be rotated towards the vector input.
