When I add a plane and rotate it by 90 degrees on the X axis, it cannot be seen when it gets rendered even if the camera or the plane is moved. However, rotating the plane approximately 90 degrees causes it to render and show correctly.
When the plane is rendered at a completely 90 degree angle, scrolling back and forth to adjust camera view won’t show the plane. However scrolling around when the plane is rendered at a close to 90 degree angle, it works.
The code is here, and you can change line 17 between ‘approx’ and ‘ninety’ to see.
I may be missing something obvious or am oblivious to some fact, but it is completely puzzling at this point.
