Hello Everyone,
I'm writing a game using OpenGL in which you play as a tank that can shoot shells. The shells are drawn via instanced rendering, and the instanced vertex array is simply a tightly-packed buffer of Vector3<f32> that gets updated every frame with a call to glBufferSubData().
The strange thing is that while my game's actual output is wrong, RenderDoc's frame capture shows me the output I would expect. The following screenshots were taken right after firing a couple of shells (sorry if they're a bit hard to see).
