Hey, I checked out your mod and it's awesome.

One thing I noticed is when increasing / decreasing the size of the belt brush line the orientation of the brush is always set to north. Would it be possible to keep the orientation the brush was in?

Sorry for taking so long to respond about this. Sadly I haven't been able to find any way to actually get the direction of the held entity (actually if I remember correctly I think I read somewhere that the devs purposefully don't want to expose this information to mods) so unless things change in the api it's not possible.

Alright, thanks!

I remember the original picker belt brush keeping the orientation and was curious how they did it, I asked around the technical discord and found out you can get the event for when the user rotates the blueprint and maintain internal state for the rotation.

I'm just leaving this here, I have no expectation of you doing anything about this. Cheers, great mod!
