Are you working on 3D modeling and want to remove the MTL file from an OBJ? Here's a quick guide to help you with that!

Step 1: Open the OBJ file in a text editor such as Notepad or Sublime Text.

Step 2: Search for the MTL file reference within the OBJ file. It will look something like 'mtllib filename.mtl'.

Step 3: Delete the line referencing the MTL file from the OBJ file. Make sure to save the changes.

Step 4: If there are any material properties in the OBJ file that reference the MTL file, you will need to remove or update those as well.

That's it! By following these simple steps, you can easily remove the MTL file from an OBJ in your 3D modeling project. This can be useful if you want to make the OBJ file more portable or if you no longer need the material information from the MTL file.

Remember to always backup your files before making any changes, just in case something goes wrong. Happy 3D modeling!
