I am using the HillTree_02 tree from the KiteDemo.
I am using the HTC Vive.
While looking at the billboard-version of the tree through the Vive something weird happens:
If i tilt my head the billboard rotates with head, distorting its shape in a weird way. Also if I’m turning my head it seems to rotate in the z-axis, becoming thinner.
I tried creating a simple billboard material to test with, and it behaves in almost the same but not entirely similar way. It is rotating with my head but does not seem to distort the image.
