Mesh Blend – Alpha Blend – Soft Particles – Blend between water and ground

Blend 2 Meshes

Proximity Fade in OpenGL is fixed in Godot 4.6, simply enable it in the material properties of your mesh.

In Godot 4.5 changing Scaling 3D will spam errors and make your mesh invisible.

To use this code in earlier versions you would need to recompile your engine with the fix.

Add the shader to your shader code.

Remove the “if” statement if you only use one renderer. If you are gonna support both Vulkan and OpenGL keep it.
