How to render a water?

Question

I added area and calculate Archimedes Force and change state if player inside that area, so we can swim.

But how to render a water in that area? Can you give me some tutorial how to correctly implement water in 3d game?

Answer 1

If performance is your goal, you could make a simple but fast water material using SpatialMaterial:

• Create a MeshInstance with a new PlaneMesh.
• Create a new SpatialMaterial in the MeshInstance's material override.
• Set Albedo to a dark, translucent color.
• Set Roughness to 0 and metallic to 1.
• Use a normal map texture that represents some waves.
• Optionally, you can enable refraction to distort what's below the water.
• Optionally, you can enable Proximity Fade to make water edges fade in smoothly. This is only supported when using the GLES3 renderer.
• Create an AnimationPlayer node and use it to animate the SpatialMaterial's Uv1 offset property. This will make the texture scroll over time.

To make waving water, you'll need to write a vertex shader though.
