Hello,
I’m having trouble to figure out, how set the rotation of an instance to exactly match the rotation of another instance. I tried to initially reset the rotation, by multiplying the instance rotation node by -1 and plug into rotate instances node, then I wanted to grab the rotation of my target instances and rotate again. However already the reset to 0 is not working. Maybe some of you know, how I have to approach this.

Rotations don’t work like that because the order of operations remain the same and will change the outcome…

To explain this point look at the below network where the steps are being explicitly done one at a time and see how multiplying the rotation by -1 won’t invert the rotation:
