In hedgehog engine games, each sub-mesh has a layer assigned that can enable or disable certain shader features for rendering, as well as change when it gets rendered.

== Opaque ==
The default mesh layer, which completely ignores any transparency of a material.

In hedgehog Engine 2 games, this layer will attempt to use [[Hedgehog Engine 2 - Deferred Rendering|deferred rendering]].

== Transparent ==
Will render meshes with transparency blending. Makes use of the “use additive blending” feature.

== Punch-through ==
When rendering a mesh, each rendered pixel will check if the sampled transparency is below the materials “clip threshold”. If it is, the pixel is discarded.

In hedgehog Engine 2 games, this layer will attempt to use [[Hedgehog Engine 2 - Deferred Rendering|deferred rendering]].
