Lightweight Render Pipeline Shaders

"Lightweight Render Pipeline Shaders" is a collection of shaders designed for Unity 2018 Lightweight Render Pipeline. It's especially useful for VFX and particles.

All shaders are fully customizable and GPU Instancing / GPU Instancing Particles friendly.

Features

Basic Parameters

This section contains shader specific parameters. Basically, color and texture.

Alpha Clip

If you check Alpha Clip, alpha clipping is enabled. A pixel with alpha that is less than threshold will be discarded.

Surface

You can choose one of the following surface types:

• Opaque
• Transparent
• Premultiply
• Additive
• Multiply

and Src Blend, Dst Blend, Z Write and Premultiplied Alpha values will automatically be configured to appropriate settings.

If you choose Custom, you can change that values as you like.

Cull

You can choose a cull mode from:

• Off
• Front
• Back

Default is Back. Off is for double sided material.

Z Test

You can choose which compare function will be used for Z Test.

GPU Instaincing

If you check Enable GPU Instancing, a material is automatically configured for GPU Instancing. If you use same mesh and the material with MeshRenderer for rendering, draw call will be automatically instanced.

Also if you check Enable Per Instance Data, you can store per-instance Basic Parameters via MaterialPropertyBlock.

// Set random colors but keep GPU Instancing
foreach (var g in gameObjects)
{
  var property = new MaterialPropertyBlock();
  property.SetColor("_Color", Random.color);
  g.GetComponent<MeshRenderer>().SetProperty(property);
}

GPU Instancing Particle

All Particles shaders works correctly with GPU Instaincing in Particle System.

To enable GPU Instaincing in Particle System, use Mesh render mode and check Enable GPU Instancing in Render section of Particle System inspector.

Minimum

All features are implemented by shader variants. After compilation, code of non-used feature is efficiently striped!
