Hell yeah

[gheskett]

Please repoint this to HackerSM64 2.4, since this isn't going to introduce any major conflicts (although it will conflict minorly with Lighting Engine).

[gheskett]

LGTM, assuming this was tested with newest changes and both with and without a DL.

[arthurtilly]

would it perhaps be possible to make this a parameter for the command rather than a new ID? (can create a compatibility macro with one fewer param for existing repos / fast64)

[gheskett]

If the code isn't too different, I'd agree with this honestly

[LucretiaArc]

Done, node pos/direction to camera version is gone now too, but easy to readd if needed

[arthurtilly]

looks better now but tbh i'm not totally sure how necessary axis is either

[LucretiaArc]

The axis param is very helpful in cases where the axis you want to use isn't aligned to X, Y, or Z. For example, if someone adds a billboarded rope to their level, they can translate the node to one end of the rope, then set the axis to the relative position of the other end. If we force people to use a rotation node for this, they'll have to calculate the angle themselves.
