When fixing FBX 3D models for clients, start by diagnosing common issues (missing textures, broken geometry, animation glitches) with tools like Blender, Maya, or 3ds Max, then apply targeted fixes, test compatibility, and align with the client’s workflow.
Use built-in tool features to resolve specific problems: Blender’s "Merge by Distance" fixes overlapping vertices, while Maya’s "Texture Manager" relinks missing textures.
Test the model in the client’s target app (e.g., Unity, Unreal) to ensure it works—this catches compatibility issues early.
Match your fixes to the client’s workflow: If they share import settings (e.g., embedded textures, axis orientation), follow those to avoid repeat problems.
