-At first glance, this seems just fine, but OpenGL experts would likely see a problem with the structure. Our fields aren't aligned properly to support the `std430` alignment that storage buffers require.. I won't get into detail but you can check out the [alignment showcase](/showcase/alignment) if you want to know more. To summarize, the `vec2` for the `tex_coords` was messing up the byte alignment, corrupting the vertex data resulting in the following:
