A directional light has been put into the bloodstream scene, however it hardly made a difference as the majority of objects in the scene were textured with shading maps. This meant they were all in block colour and no shading could be seen in the renders. With some help the models texture was changed back to lamberts and the directional light was adjusted to create a more block effect. On my worm character I attempted adding a two tone light angle, but this took away the UV texture map away. So I tried adding the UV map onto the two tone texture but this didn't work, though I might attempt this again.
