Describe your issue：Light and highlight texture error, is there a way to solve it?

[WesterlyGraph68]

What happened?

These errors usually occur when the weather in the game is rainy (other shaders don't have this issue). The highlight textures make me feel like something went wrong. Is there a way to fix this? ↓

What I think the highlight textures should look like when they're working correctly. ↓ I'm using a PBR resource pack. ↓
