(Current release of Gaia Pro (2.1.4)- found commonly with Mac Users)

This article will help fix the issue of water lines and grid issues that may appear to mainly Mac users but could affect others as well.

This is an issue with Metal graphics API and the water shader,
 
They can do the following to fix this issue until we come up with a better approach to this:
 
- Open the water shader file in Assets\Procedural Worlds\Gaia\Shaders\PW General\PW_Water.shader
In line 61, remove the two leading slashes "//" to comment in the command "ZWrite Off" This should fix the issue but can create other issues when using the wave feature in the shader
 
- Switch the graphics API to OpenGL
- Switch the rendering Pipeline to URP
- Adjust the rendering queues in the shader (This is a slippery slope into having to adjust the rendering queue on other shaders as well though)
