Hittable i.e sphere can't have int types in struct. Maybe it can be coerced but the source bits will still be float in rust, but they should have a (float) index to a material in a separate buffer. Each material should hold three things: MaterialType (int), material attributes index and albedo index
Then each material type should have it's own buffer of attributes data i.e metal has the fuzzing and the attribute index will be relative to the context it is used. So in scatter_metalic we know the index is to the metalic buffer etc.
This change will simplify the code as the requirements grow and avoid padding
