Should calculate the appropriate inverted transposed matrix to multiply with the normal.

bug

Currently skybox resolution is limited because too high of a resolution results in longer than 2 seconds being taken up for the calculation of the irradiance map. This will crash...

Currently the material of an entity is applied to all child meshes. This should rather be done in an editor as it allows multiple materials per entity by applying them...

Currently we loop through all entities to find the ID stored in the AttachedTo component. The reason for this is that we have to store the parent entity by ID...
