Use Unity's timeline to blend material properties

This is a Unity Timeline extension to animate and blend material properties. It consists of two custom tracks:

Track	Description
Material Track	Change properties of a material directly, changing it everywhere in the scene.
Renderer Track	Overwrite a selection of a renderer's material slots, changing only one specific object.*

* Material Property Blocks are used, so instancing isn't broken.

Features

	Material Track	Renderer Track
Layers (a.k.a. Override Tracks)	✓	✓
Clip extrapolation	✓	✓
Set/Blend Float/Range/Color/Vector	✓	✓
Set/Blend* Texture2D/RenderTexture	✓	✓
Set/Blend Texture Tiling/Offset	✓	✓
Set Texture3D	✓	✓
Blend Texture3D	✗	✗
Set CubeMap	✓	✓
Blend CubeMap	✗	✗
Overwrite with entire Material**	✓	✗

All blending can be done between two clips, or with the original value set in the material.

* See Use texture blending for how to activate this feature.
** Just uses Material.Lerp internally, so it's not able to blend textures.

Installation

In your project folder, simply add this to the dependencies inside Packages/manifest.json:

"com.d4ku.material-timeline": "https://github.com/D4KU/unity-material-timeline.git"

Alternatively, you can:

• Clone this repository
• In Unity, go to Window > Package Manager > + > Add Package from disk
• Select package.json at the root of the package folder

Use texture blending

This package ships a shader to blend textures, named TextureBlend. To tell Unity to include it in builds, even if no scene has a dependency to it, add it to the list of always included shaders under ProjectSettings > Graphics. Without this shader the package functions normally, but textures are switched instead of blended.
