Soggy Shaders

A collection of shaders by yum_food.

MIT licensed: feel free to modify, redistribute, and sell!

To use, clone this repo somewhere inside your Unity assets folder. Then assign the shader you want (like yum_food/parallax) to a material.

Please ask setup questions on the discord.

Grass (yum_food/grass)

A simple geometry shader that repeats a tile of grass 16 times and uses a noise texture to apply a wind effect on the geometry.

Right now only the noise texture is configurable.

Measured @ ~3.0 ms per frame at 4k

TODO: add a mask to enable controlling where grass spawns.

See Shaders/grass/grass_10m_tile.prefab.

Parallax (yum_food/parallax)

A simple parallax shader with three parallax planes. Each plane can be textured with PBR textures: base color, normal, metallic, and roughness. The size, depth, and emission strength of each plane is configurable.

In these demos, I have the shader on a quad.

Full demo video here.

Displacement (yum_food/displacement)

A simple displacement shader.

• Displacement height is specified with a texture.
• Height texture can be translated at configurable X/Y speeds, giving a flowy effect.
• Height can be masked to concentrate height mapping into specific areas.
• A built-in center-out effect is available.
• Basic physically-based shading is implemented (albedo with alpha, normal, roughness, metallic, cubemap).

In these demos, I have the shader on a 100x100 plane.

Full demo video here.

Avatar cloning (yum_food/avatar_clone)

A cloning system using a geometry shader.

• Same features as the displacement shader.
• Spawn up to 4 clones at controllable x/y/z offsets (in meters).
• Clones spawn on the left or right side, in alternating order.

To use it in game:

• Assign the shader to all material slots you want to clone.
• Assign textures.
• Create 4 animations:
  • Set number of clones to 0.
  • Set number of clones to 4.
  • Set clone X offset to 0.
  • Set clone X offset to 1.
• Create 2 float params:
  • Clone_Count: controls number of clones.
  • Clone_dx: controls each clone's X axis offset.
• Create 2 layers in your FX layer:
  • One uses Clone_Count to blend between 0 and 4 clones.
  • One uses Clone_dx to blend between 0 and 1 x offset.
• Create two radial puppet controls, one for Clone_Count, and one for Clone_dx.
