- line 97: Compilation error using vec instead of vec2. Found through compiler error
- line 101: Raycast used uv instead of uv2. Found by rendering just uvs as color and noticing they were shifted
- line 11: Aspect ratio transform was using x/x instead of x/y. Found by rendering ray directions
- line 18: Iteration count was too low to see much ground. Found by noticing effects around edges of spheres, which I knew that when ray marching could be caused by approaching tangent surfaces.
- line 75: Made sure to reflect dir instead of eye about the normal. Found by rendering the reflected direction as color
