Let's Fix Your React Three Fiber Projects

I did many project tutorials, but unfortunately, 3D web development is what it is. There are a lot of factors that can make a project run fine on my computer when I record it and just crashes on yours.

While I could say works on my machine… Which is sometimes what I want to reply when I receive tons of private messages on Instagram/Discord/or Twitter.

Actually I’m here to help you learn and unlock you! That’s why when you are blocked ask for help on our Discord community. Awesome developers and I are always willing to help.

That being said, most of the help requests are fair, and I’ve picked the most common ones happening on the 3D Portfolio and the AI Virtual Girlfriend Chatbot.

Even if you don’t have those issues yet, the content might interest you because it covers how to fix it but mainly why it happens for some users while we are following the same tutorial.

The Most Common Issues and Their Fixes

Portfolio Avatar Positioning

Issue: Your avatar might not be positioned correctly, causing misalignment in your 3D portfolio.
Solution: Set the Y Forward and Z Up positions correctly and make sure the Three.js version is aligned with the r3f-vite-starter.

Portfolio Avatar GitHub

Console Error: Some additional data in your animation file (from Mixamo) may show up as an error, but it’s harmless and doesn’t affect the animation itself. You can safely ignore it.

Head Disappearing in Portfolio

Issue: Your avatar’s head vanishes when moving or rotating the model.
Solution: This is typically due to frustum culling, which removes objects outside the camera’s view. You can disable it with this fix: Three.js Object3D.frustumCulled.

Issues with ChatGPT OpenAI Bot

Problem: When implementing AI-driven features, sometimes you run into compatibility issues or failed integrations.
Solution: Ensure your environment is set up correctly with Rhubarb, OpenAI, and Eleven Labs APIs.
