🌊 Ocean Shader
Champagne Shores
A stylized ocean shader for InnerSpace.
Designed to improve style and performance, the surface shading and shallow depth-transparency allow nearly all geometry below the shoreline to be hidden & culled.
Texture warping around islands, obstructions, & other landmasses
Simple vertex Ambient Occlusion bake, can be performed in engine or in separate editor
Vertex AO: Bake
Vertex AO: Shoreline texture warping
Vertex AO: Motion clamping
Vertex colors are added near islands via a simple vertex Ambient Occlusion bake.
This bake defines the transition between the deep & shallow water shading styles, and influences the strength of the texture warping around shorelines.
These areas, and any user-defined vertex painting, are further used to clamp the water's motion, preventing geometry clipping in shallow areas.
With pre-pass
Without pre-pass
The shader also uses a depth write pre-pass to prevent self-occluding transparency-sorting errors.
The above link has since broken.
Here’s an updated link to the Gerstner Wave documentation.
Wave motion is driven primarily by Gerstner Waves (used for the water in games like Uncharted & Dishonored, documented here) along with additional custom noise & further modifications to compensate for the spherical water surfaces of InnerSpace.
