Camera matching a cartoon character

For an upcoming project i went on a 360 photosafari in a hospital. Shot 3 hdr panorama's of places where patients with kidney failure go. The images are meant to light the scene with a matching backdrop. Theta z1 to the rescue. Took notes and measured each scene (lens distortion and sensor, lens size) only to find the c4d camera solver decides differently on the reconstruction of the scene. Perhaps a 1 meter wire cube will work better. To place the light accurately i made myself a reflection and shadow ball for a few euro's. The xrite color pasport came in very handy for color consitency. Substance alchemist helped a lot with the textures. Very happy with the stability of S24 and RS.
