Issue with Materials not Loading after Downgrading three to version ^0.125.2

[GegaAbzianidze]

Hi there,

I recently downgraded three to version 0.125.2 in my project, but I'm experiencing difficulties with loading materials. Specifically, the materials are not appearing as expected. I noticed that the gltfjsx tool, which generates JSX code for GLTF models, uses Three.js version 0.125.2, so I expected compatibility.

Here are some details regarding the issue:

1. The materials were working fine in my previous version of Three.js.
2. I have compared my code and GLTF models with the example code provided by the gltfjsx tool, and I haven't identified any significant differences.
3. I have checked the browser console for error messages, but I haven't found anything related to materials specifically.

Could you please help me understand what might be causing this problem? Here are a few questions I have:

1. Are there any known compatibility issues between Three.js version 0.125.2 and the materials system?
2. Has there been any change in how materials are defined or used in Three.js version 0.125.2 that I should be aware of?
3. Is there any specific configuration or setup I need to ensure when using materials with Three.js version 0.125.2?
4. Could the GLTFLoader in Three.js version 0.125.2 have any differences or issues when loading materials compared to the version used by the gltfjsx tool?

Any guidance or suggestions on troubleshooting this issue would be greatly appreciated. Thank you in advance for your assistance!
