The custom blocks render inconsistently with vanilla dirt/grass when using shaders

[nerdifly]

The custom eroded dirt/grass blocks added by the mod appear visually inconsistent compared to vanilla dirt and grass blocks when using a shader.

The issue is most noticeable during sunrise and sunset, where the vanilla terrain receives lighting and reflections differently than the eroded variants, making them stand out significantly despite being intended to blend naturally into the terrain.

Environment

• Minecraft: 26.1.2
• Mod version: 0.5.1-26.1.x-fabric (latest)
• Loader: (Fabric)
• Shader: Complementary Unbound r5.8.1

Expected Behavior

The eroded dirt and grass blocks should receive the same lighting (material) as vanilla dirt and grass, allowing them to blend seamlessly into the surrounding terrain.
