Error on Rotation and Translate.

[ManChrys]

Hello,

Question 1

ive tried [QRSubScene] and after i measure all distances from the top left point of QRcode_1 (real world) i put them to unity, but i have problem in rotation and translate. Even if the walls are perpendicular the hologram, after qr code scanning, is not right.

If i want to fix the error on image 2 i have to make a rotation, but i dont know why. It shouldnt spawned correctly and with accuracy ?

Question 2

If QRcode axes is like image below hologram spawns correctly.

If QRcode axes is like image below hologram spawns on the opposite side even if axes of all objects have the same orientation.

The orientation that i pin the qr code on the wall (real world) is the same as image

Thanks in advance.
