fix: disable vertex colors on GLTF models to remove triangle artifacts#1263
Merged
Conversation
AI-generated models (Tripo/Meshy) often bake ambient occlusion into vertex colors. The GLTFLoader automatically enables vertexColors on materials when it detects color attributes, causing the dark AO data to be multiplied with the base color and creating visible triangular artifacts on all model surfaces. This fix disables vertexColors on all mesh materials after GLTF loading in both loadGLTF() and loadGLTFForLOD() methods. The color attribute data is preserved in case it's needed, but it no longer affects the visual appearance. https://claude.ai/code/session_012kqvccEiiHNQHAjUEoposi
