Hey guys, I'm trying to figure out a way to rotate some billboard quads in 2 axis, x and y (ignoring rotation around the z axis, essentially). I've followed some forum posts online without much success and most of the content seems to be tailored towards only rotation around 1 axis.
I'm pretty new to shadergraph so I'm probably way out of my depth here, does anybody have an idea of how I would approach this?

as far as I can tell, the red bit is where the rotation is actually happening
but not sure how I can actually limit the rotation, I've attempted to split out the transformation matrix into a separate vector4 node and then link it back to the system, but it seems to return something completely different

Alternatively I think you can manage it with:
https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@17.0/manual/Operator-Rotate3D.html
And just rotate it on both the y then x after grabbing the angle difference (signed angle) from the camera

heya Mao, thanks for the link - I'll take a look! I've also been pointed to using particles which might be the more performant option and it includes a way to disable rotation already!
(the clouds in the screenshot were just quads), it was always eventually going to be a particle but didn't know the system alrady had this option
I will still end up using it as I think I'll need to use some kind of LOD approach where the particle systems are replaced with billboards in the distance

Yeah, vfx graph is not a bad idea and I think there's support for a custom billboarding angle (I think it's the advanced setting for camera alignments?) otherwise you can use a similar rotate 3D node inside of it ;p
