Configurable Shaders

A system to mix and match different ORL shader modules together to get the result you want

What is a Configurable Shader?

A configurable shader is a shader that is made up of one or multiple modules provided by the ORL Shaders package.

If you ever wanted to "add LTCGI to VertexAnimation shader" or "have support for distance Dither Fade in the Layered Material shader" this tool is for you!

Creating a new Shader

Making a new Configurable Shader is super easy! Just right click in your project window and select Create -> Shader -> orels1 -> Configurable Shader. Give it a name at the top of the inspector that opened and you're good to go!

Modifying the Shader

By default, the shader uses the PBR lighting model, which is good for most cases, and only the BaseColor module is included, which renders a texture tinted by a color.

Let's make something more interesting and add a Dissolve module.

Click on the + button in the Modules section to add a new module. And change it to Dissolve

Dissolve Module Selected

If you make a new material and assign this new shader to it - you'll see that it has all of the options of the Dissolve shader.

Using a Base Shader

Sometimes you only want to slightly tweak a shader that already exists. E.g. add LTCGI support to the Vertex Animation shader.

This can also be easily done with Configurable Shaders.

Instead of adding every module by hand, simply select ORL Standard Vertex Animation in the Base Shader dropdown and remove the BaseColor module, as we don't need it anymore.

Vertex Animation Base Shader

Now you can add the desired module in the modules list and it will be "stacked" on top of the base shader.

And that's it! You can use this new shader as you would any other in your project, and it will benefit from any future updates I make to either base shaders or the modules.

Things to keep in mind

There are some caveats to the system that you should be aware of. The inspector will try to do its best to tell you if any issues are expected, but it's not perfect.

• You should not have repeating modules
• You shouldn't use BaseColor modules with Base Shaders
• Toon modules work best with the Toon Lighting Model or a Toon base shader
• Use VFX for best performance, unless you need PBR features like lightmapping or reflection probes
