For octahedral compressed normals/tangents, we use vec4 in the shader regardless of whether a normal/tangent does/doesn't exist For the case where we only have a normal vector, we need to specify that there are only two components being used when calling glVertexAttrib Before we would always specify that there were 4 components, and used offsets to determine where in the vertex buffer to read data from but this doesn't work on all platforms
