How does it work?
When you specify files with absolute paths and later move them, you must change these paths to reflect new locations. To prevent this, use relative paths that specify paths or files.
When you use a relative path, instead of referring to a file relative to the project's root folder, the path is stored relative to the .mtl file which provides reference to the texture file.
For example, if the texture is located in the same folder as the .mtl file, it will be referenced as File="./house.tif". If the file is located in a subfolder called textures, it will be referenced as File="./textures/house.tif".
Please refer to the sample *.mtl file below:
This feature enables the user to easily share assets through Marketplace, and for prototyping.
During the optimization stage of your project, you might want to share textures between materials or objects to optimize the memory footprint of your project.
