Block Render Layers

File location

(shaderpack)/shaders/block.properties

The custom block render layers are defined in shaders/block.properties included in a shader pack.

Warning

Blocks which are solid opaque cubes (stone, dirt, ores, etc) can't be rendered on a custom layer as this would affect face culling, ambient occlusion, light propagation and so on.

Properties

layer.solid

Values: List of blocks
Optional

No alpha, no blending (solid textures).

layer.cutout

Values: List of blocks
Optional

Alpha, no blending (cutout textures).

layer.cutout_mipped

Values: List of blocks
Optional

Alpha, no blending, mipmaps (cutout with mipmaps)

layer.translucent

Values: List of blocks
Optional

Alpha, blending, mipmaps (water, stained glass).

Example

layer.translucent=glass_pane fence wooden_door
layer.cutout=oak_stairs
layer.solid=stone dirt
