Welcome to the legacy site! It's a bit broken, but should work for the most part - just keep in mind I'm not actively maintaining it!

Miscellaneous settings are settings that didn't really fit anywhere else.


The LOD defines how likely Unity is to use the custom shader compared to the fallback. On a worser GPU it can be faster to use a default Unity shader than a custom one. Increasing the LOD tells Unity the shader is more complex. 200 is good for a diffuse shader, with 600 being more complex, like using POM or specular highlights.

Shader Model

The Shader Model is important in choosing what hardware will be able to run the shader. The lower the Shader Model, the older the hardware, but the more limitations. Shader Model 3 is the default since it runs on computers from over 10 years ago, and has very little limitations on the shader. Shader Model 2 limits the number of layers and effects you can use severely. If the shader turns pink and you're using SM2, I'd recommend increasing it.

Cull (All, Front, Back)

Changes which parts of the model are visible. All makes the entire object visible, Front makes only the front facing faces show, and back makes only the back facing faces show.

Use Ambient

Ambient lighting is a base color that is applied when lighting, and can be changed in Unity 5's Lighting panel.

Use Lightmaps

Lightmaps bake, or save lighting to a file, so that objects can be rendered quicker. Disabling this can make the shader smaller and quicker, but removes the ability to bake lightmaps with it.

Interpolate View

Compute the view direction in the vertex shader instead of the fragment (pixel) shader, which is faster but may cause an error when used with some other settings.

Use Vertex Lights

In forward rendering mode, Unity can make lights apply per-vertex instead of per-pixel to speed up rendering. Disabling this makes the object be lit by less lights, and may have light popping.

Use Fog

Fog is an atmospheric effect that makes objects blend into a color with distance. Disabling fog makes the object always visible, even in foggy conditions.

Half as View

When enabled speeds up lighting slightly at the cost of accuracy.


Enables shadow recieving support, when disabled the shader is faster and smaller.

Forward Shadows (Must enable Shadows)

Forward shadows enables shadows in forward rendering mode. By default shaders only support one shadow from a directional light in forward rendering mode, but with this enabled it can accept shadows from any light.

Forward Add

Allows the shader to use more than one directional light when in forward mode. Disable for a faster and smaller shader, at the cost of only supporting a single direcional light.
