### Description of the bug:
When using SM64-Reloaded Texture Pack (v2.6.0), a lot of textures are glitchy.

### Can you reproduce? If so please list the steps:
- [ ] No, I cannot reproduce this bug
- [x] Yes, here are the steps to reproduce the bug:

### Expected behavior:
Texture Pack from GhostlyDark should work perfectly on Ghostship v2.0.0 but it doesn't.
Works only on Ghostship v1.0.2 (Tested).

### Screenshots or videos:

### System Information:
- OS: Windows 11 25H2

Start by reproducing the GhostlyDark SM64-Reloaded Texture Pack v2.6.0 issue on Ghostship v2.0.0 under both DirectX and OpenGL, then compare the result with Ghostship v1.0.2. Trace the texture-loading or rendering path responsible for the glitchy textures; done means the pack renders correctly on v2.0.0.
