I’m using an HTC and trying to use the “Draw Debug Sphere” blueprint node to draw debug geometry. When I try to do this and view it within VR Preview, I am getting display errors. If I look through my right eye, I can see the debug geometry without any issues. If I look through my left eye, it is gone. However, if I rotate my head, the debug geometry will appear but the projection looks way off (as if it were flattened onto a cylinder).
I’m using an unmodified UE 4.13 source build and I can replicate the problem within my project and a blank VR template project. The problem seems to apply to the draw debug sphere, draw debug line, and most likely all of the debug draw commands. When I view the scene through the preview window on my monitor, it looks wrong as well (I think its rendering the left eye).
This was not a problem for me in 4.12
