Are you looking to import OBJ files into After Effects but don't want to use any plugins? You're in luck! With the help of JSON format, you can easily accomplish this without the need for extra tools.

Here's a step-by-step guide on how to import OBJ files into After Effects without using any plugins:

1. Prepare your OBJ file: Make sure to have your 3D model saved in the OBJ format. If you don't have an OBJ file, you can use 3D modeling software like Blender, Maya, or 3ds Max to export your model as an OBJ file.

2. Prepare your texture files: If your 3D model has textures, make sure to have them ready as well. Textures can be in various formats such as PNG, JPEG, or TIFF.

3. Convert OBJ to JSON: After Effects does not natively support the OBJ format, but it does support JSON. You can convert your OBJ file to a JSON file using online conversion tools or scripts in 3D software.

4. Import JSON file into After Effects: Once you have your JSON file ready, you can import it into After Effects. Go to File > Import > File, and select your JSON file. After Effects will then import your 3D model along with its textures.

5. Adjust settings: After importing the JSON file, you may need to adjust the scale, position, and rotation of your 3D model to fit your composition. You can do this by selecting the 3D layer in After Effects and using the transform properties to make the necessary adjustments.

6. Animation and rendering: With your 3D model imported, you can now proceed to animate it and set up your scene in After Effects. You can add lights, cameras, and apply effects to enhance your 3D composition. Once you're satisfied with the result, you can render your composition for the final output.

By following these steps, you can easily import OBJ files into After Effects without the need for any additional plugins. This method allows you to work with 3D models directly in After Effects using JSON format, giving you more flexibility and control over your 3D compositions.

So, next time you need to import a 3D model into After Effects, remember that you can do so without relying on external plugins. With the power of JSON and the built-in capabilities of After Effects, you can bring your 3D creations to life seamlessly.
