Completed the final gathering, then moved onto the spotlight to add illumination.
I forgot that when I was starting up the scene in the first place I was having issues with the HDR/IBL lighting. The reflection light probe was showing up some crazy reflection apart from the actual reflection cards that I had created.
I had used both the HDR and a blurry version of it (for use in FG) and had both of those inputted into a mib_lookup_spherical and then both of those into a mip_rayswitch. It then used the blurry version for the FG and the HDR for the reflections.
It all seems pretty happy now though and I just need to render out the camera animationThe only thing I need to do before I render the camera pass out is to redo the dirty texure around the base of the house as it is, frankly a bit off.
