Description of the Bug

When utilizing the AssimpLoader to load 3D models, a critical issue arises when dealing with materials that employ embedded textures. Unfortunately, these embedded textures are not handled correctly, resulting in their complete disregard. This oversight can significantly impact the overall visual fidelity and accuracy of the 3D model, making it essential to address this issue promptly.

To Reproduce the Bug

To replicate this issue, follow these steps:

Open an issue with embedded textures: Select a 3D model that incorporates embedded textures. A suitable example can be found at the NASA 3D repository:
- https://nasa3d.arc.nasa.gov/detail/acrimsat
Check for loaded embedded textures: Inspect the loaded model to verify that the embedded textures are not being loaded as expected.

Expected Behavior

The expected behavior is for the AssimpLoader to correctly handle embedded textures, ensuring that they are loaded and displayed accurately within the 3D model. This is crucial for maintaining the model's visual integrity and overall quality.

Additional Context

The AssimpLoader is a widely used library for loading 3D models in various formats, including those with embedded textures. However, the current implementation appears to be flawed, leading to the neglect of these critical texture components. To resolve this issue, a thorough examination of the AssimpLoader's texture handling mechanisms is necessary, followed by the implementation of necessary corrections to ensure accurate loading of embedded textures.
