Hello, Muhammad here! Leveraging my skills in Blender and JavaScript, I'm confident that I can create an HTML page based on ThreeJS that seamlessly combines your OBJ model, Mixamo animations (FBX files), and facial expression textures (PNGs). Drawing from my familiarity with GLTF, I intend to develop a Javascript code that delivers a smooth and dynamic animation for your 3D model.
I recognize the challenge of integrating armature data from FBX files into OBJ models while retaining texture data. However, this is precisely where my Blender proficiency comes into play. By leveraging its capabilities, I'll find an optimal way to merge these components seamlessly and deliver an elegant solution for your project within mere 300 lines or so of Javascript code, relieving you of what has been a cumbersome process thus far.
Undoubtedly, experience matters in any trade, but it also matters how one approaches challenges while staying relevant. Being an aspiring web developer, my technological curiosity drives me to constantly learn and explore new technologies, which makes me adept at solving innovatively even if faced with unfamiliar issues. With me by your side, you can bet not only on competence but on enthusiasm and resourcefulness too. Let's transform your project together!
