For those working on facial modeling and character rigging, I've been using some helpful AI analysis tools that speed up my reference workflow.

FaceAuraAI has several free tools that work great alongside C4D:

Face Shape Detector - Quickly analyze reference photos to determine face proportions (oval, square, heart, etc.) before starting your base mesh

Face Symmetry Analyzer - Check reference images for symmetry to inform your modeling decisions

Golden Ratio Calculator - Helpful for analyzing facial proportions when aiming for realistic or stylized characters

Emotion Detector - Useful for analyzing facial expressions when creating pose morphs

These work entirely in-browser, no signup needed. Just upload a reference photo and get instant analysis. Been using them to speed up my pre-production phase before jumping into modeling.

Thought this might be useful for others doing character work or facial rigging.
