The instances of a grid rotate wrongly. I want a rotation only in the y direction but the rotation is done in the x and y direction. enter image description here

I must be something essential that I'm doing wrong... How do I pass on the distance value from the proximity node as a y vector value?

Thx!

    $\begingroup$ A note in addition to @Chris' answer: Map Range->Separate XYZ casts a Float to a Vector, which will fill X,Y and Z of the vector with the same float. Then SeparateXYZ(Y)->Rotation does it again,. You could replace Separate XYZ with Combine XYZ . $\endgroup$

try this node tree:

enter image description here

enter image description here

several things you should know:

  • Blender and GN are working internally with radians, not degrees. So if you want to rotate a half circle, the correct value is Pi, not 180 degrees.

  • the map range node of type float outputs a float. So it makes no sense to separate a float to xyz value.

  • you want to use the combine xyz value - which takes 3 floats and makes a vector out of them

Hint: you can enter "pi" in a value field - Blender knows it

Hint 2: you can enter "tau" in a value field - which is 2 * pi
