There’s quite a bit of confusion I can’t follow here.
- you’re not drawing a plane, you’re rotating an actor that owns a mesh component. Correct?
- the rotation in the last pic is not 90. It’s 45 degrees. Correct?
- is it local / world / actor / component? Too many unknowns…
What is the ultimate goal? Have a 45 degree plane rotated towards the camera?
Note that the pin order of the Combine Rotators node matters.
And then there’s @ClockworkOcean suggestion. Learning is great but perhaps you’re trying to learn the wrong thing and this solution is the one to go for. Definitely most performant and least fussy.
