I agree, i'm very supportive of different CGI styles but the KH Nomura art style just doesn't work very well in 3D. The eyes specifically always look incredibly lifeless and the skin shaders and modeling make them look like dolls which at this fidelity coupled with the Nomura edginess looks terrible.
and holy fuck I'd hate to work with any one of these rigs because the lack of proper blendshapes means the range for expressions is piss poor by every standard
they literally got more limited overtime, this was KH1
why are they torturing these animators man. "So wait, you made me a new rig for the new intro and CGI shots, and it's more limited than the last one? Wait, ALL of them are more limited than the previous versions? The hell am I supposed to do with this??" ಠ_ಠ
The Good Dinosaur had a similar issue to KH in terms of rendering with the less realistic models looking very out of place on these incredibly realistic backgrounds. The slight stylization of the luminous target render did a incredibly good job at alleviating most of the above issues. First off, they aren't afraid to give the ingame models actual blend shapes so that they can make a range of expressions, also helps that the background was also stylized, not just the characters.
