Hello Everyone
Is there a tutorial for a ceiling projection with to procectors (x2,y1)?
If I make a ceiling projection, i think i need to turn the screen upside down, to get the projectors to map correctly (upside down) to the screen.
But if I do this, eather the projectors are right and left swapped, or the testpattern is from outside to inside, there must be something I am doing wrong.

Best Regards

Hi Zeno,

well, you are closer to the solution than you might think.
If you see your testpattern/content swapped (rear projection) then the reason is that the screen is rotated in the wrong direction.
So in the "Screens" tab, choose your screen and check the "Rotation" field.
If the rotation value has a minus position then change it to a positive one (-90 to 90).

Unfortunately there's a small bug in this situation so you can't choose exactly 90 degrees. But you can insert the value 89.99 and then you should get the right image on your output!
