Yes , and the reason why is the game assumes you are holding a vive wand for all line attacks no matter what wand orientation you use (for those affected)
This is me running steam orbus thru oculus sdk on a cv1
Pointing straight at a target my line attacks will display hitting target but no damage
The line is shooting 45 degrees upward without a visual que to the caster.
Could be wrong but I believe when I was on Oculus CV1 using Steam that line attacks were correct, in Reborn (certainly preborn). But it’s been too long to remember. If you are running Orbus in compatibility mode or open vr it always defaults to the Vive though.
