Aruco marker orientaion problem

hi all

with any image as marker the orientation is correct

see here      https://ibb.co/sFKLTXF

but with intergrated aruco markers there is a 90 deg rotation between  editor ui and 3d space

see here     https://ibb.co/HGYx5WY

can you check, plz.

if i use a dummy with 90 rotation, i must rotate all related objects.


it will be perfect if we can manipulate marker position and orienation directly, with out a dummy.

Re: Aruco marker orientaion problem

Yes I added the 90° rotation on the marker detection to correct this
