Much of yesterday was spent on animating some of the final scenes, which means that to an extent, act 3 (where we see the adult) has a functional set of animations.
So today's priority was lighting. This however turned into more work than I initially anticipated as in order to shave off render times I considered looking where I could optimise my scene. Presently my shaders were monochromatic - I would create a single shader for a specific colour, but this proved inflexible and I ended up building up a number of shaders with the same settings just different shades.
I was able to replace some of the shaders using maps created in Photoshop, which I am considering fleshing out with textures to make the materials feel more like real materials and less like plastic. While other materials use a blinn, the white panels use a mila shader textured to come across more as leather, using similar properties to Four's skin due to leather's properties.
A warmer grey for the bulk material of the corridor appears to work more with the aesthetic I am aiming for. Aside from a number of hot-spots, the lighting in place (area lights positioned opposite each other) works to fill out the scene.
Strangely the frame above took considerably longer to render than the corridors, Four's teeth also appear to be reflecting the light of the surface shader used to represent the sunlight. I could disable it for when the camera switches to this shot as the effect is almost obliterating the sight of her teeth.
