Are you having trouble importing OBJ files into After Effects for your 3D project? Don't worry, you're not alone. It can be frustrating when things don't work as expected, but there are a few things you can try to troubleshoot the issue and get back on track.

1. Check your OBJ file: Make sure that your OBJ file is properly formatted and doesn't contain any errors. You can use a 3D modeling software like Blender or Cinema 4D to open and inspect the OBJ file to see if there are any issues with its structure or materials.

2. Convert OBJ to another format: If you're still having trouble importing the OBJ file, you can try converting it to a different 3D file format that is more compatible with After Effects, such as FBX or C4D. There are plenty of online converters and 3D software that can help you make this conversion.

3. Update your After Effects version: Sometimes, importing issues can be caused by compatibility problems with your After Effects version. Make sure that you are using the latest version of After Effects and that your plugins are up to date.

4. Use a third-party plugin: If all else fails, consider using a third-party plugin to help with OBJ import. There are several plugins available for After Effects that specialize in 3D import and can potentially solve your import issues.

5. Seek help from the community: If you're still struggling to import your OBJ file, don't hesitate to seek help from online forums, social media groups, or even contacting Adobe support. Many experienced users and professionals are willing to help troubleshoot and provide solutions.

Remember, troubleshooting import issues is part of the 3D animation and motion graphics process. With persistence and a bit of resourcefulness, you can overcome the challenge of importing OBJ files into After Effects and continue creating stunning 3D projects. Good luck!
