Why face 3D model is ugly in VRChat?

Face 3D models in VRChat often look ugly due to low polygon counts, poor texture resolution, uncalibrated blend shapes (morph targets), or incorrect shader settings—common VRChat model issues. Low poly counts blur fine details (e.g., eyes, skin texture), low-res textures lose clarity, uncalibrated blend shapes cause unnatural expressions (like janky smiles), and wrong shaders break lighting or skin realism (e.g., overly shiny skin). To fix it, increase polygon density (10k–50k for faces), use 2K+ textures, re-calibrate blend shapes in Blender/Unity, and start with VRChat’s default shaders for better compatibility.
