How to Import OBJ into After Effects Without Plugins

Oct 04, 2024

If you're looking to import OBJ files into After Effects without relying on any third-party plugins, you're in luck. With a few simple steps, you can bring 3D models into your After Effects compositions and start creating stunning visual effects. Here's how to do it:

1. Prepare Your OBJ File

Before you can import your OBJ file into After Effects, make sure it's properly prepared. This includes ensuring that the OBJ file is accompanied by its corresponding MTL (material) file and any texture maps it may require. If your OBJ file references external texture files, make sure they are all in the same directory and properly linked within the MTL file.

2. Convert OBJ to JSON

To bring your OBJ file into After Effects, you'll first need to convert it into a format that After Effects can understand. One common method is to convert the OBJ file into a JSON format, which can then be easily imported into After Effects using the built-in JSON parser. There are many online tools and scripts available that can help you convert OBJ files to JSON.

3. Create a New Composition

Once you have your OBJ file in JSON format, open After Effects and create a new composition. Set the dimensions and duration of the composition to match your project's requirements.

4. Import the JSON File

With your composition open, go to File > Import > File and select the JSON file that contains your OBJ data. After Effects will automatically parse the JSON file and create a new composition layer with your 3D model.

5. Set Up Your 3D Model

After importing the JSON file, you'll likely need to make some adjustments to the positioning, scale, and orientation of your 3D model within the composition. Use the 3D layer controls in After Effects to manipulate the position, rotation, and scale of your 3D model until it fits seamlessly into your composition.

6. Add Lights and Cameras

To enhance the realism of your 3D model within After Effects, consider adding lights and cameras to your composition. This will allow you to control the lighting and perspective of your 3D model, creating a more immersive and dynamic visual effect.

7. Animate Your 3D Model

Now that your 3D model is properly imported and set up within After Effects, you can start animating it to bring your project to life. Use keyframes and expressions to create movement and interactions with your 3D model, adding depth and dimension to your composition.

By following these steps, you can import OBJ files into After Effects without the need for any third-party plugins. With the ability to bring 3D models directly into After Effects, you can create visually stunning compositions and captivating visual effects for your projects.
