Render Stages

The uniform renderStage stores the “render stage” of the current geometry. This can be used to identify what type of geometry is being rendered in more detail than the gbuffer program it’s running in. The following render stages are defined by Iris as preprocessor macros:

define	Description
MC_RENDER_STAGE_NONE	Undefined (should not occur normally)
MC_RENDER_STAGE_SKY	The upper portion of the sky not including stars or textures like the sun/moon
MC_RENDER_STAGE_SUNSET	The lower portion of the sky used to generate the sunset effect, does not include textures like the sun/moon
MC_RENDER_STAGE_CUSTOM_SKY	Custom sky texture from resource pack, such as from OptiFine or FabricSkyBoxes
MC_RENDER_STAGE_SUN	Sun texture in the sky
MC_RENDER_STAGE_MOON	Moon texture in the sky
MC_RENDER_STAGE_STARS	Vanilla star geometry in the sky
MC_RENDER_STAGE_VOID	Void sky, which renders below the player when they are below bedrock
MC_RENDER_STAGE_TERRAIN_SOLID	Solid terrain geometry (terrain with no cutouts or transparent)
MC_RENDER_STAGE_TERRAIN_CUTOUT_MIPPED*	Intended for cutout geometry with mipmaps, instead these are flagged as MC_RENDER_STAGE_TERRAIN_SOLID
MC_RENDER_STAGE_TERRAIN_CUTOUT*	Intended for cutout geometry without mipmaps, instead these are flagged as MC_RENDER_STAGE_TERRAIN_SOLID
MC_RENDER_STAGE_ENTITIES	Entity geometry including nametag text
MC_RENDER_STAGE_BLOCK_ENTITIES	Block entity geometry
MC_RENDER_STAGE_DESTROY*	Intended to be used for the block cracks texture
MC_RENDER_STAGE_OUTLINE	Player block selection outline, does not include any other lines (such as fishing lines and leads)
MC_RENDER_STAGE_DEBUG*	Intended to be used for debug view lines
MC_RENDER_STAGE_HAND_SOLID	Solid or cutout geometry for held items/blocks
MC_RENDER_STAGE_TERRAIN_TRANSLUCENT	Transparent terrain (such as water and stained glass)
MC_RENDER_STAGE_TRIPWIRE*	Indented to be used for the tripwire string texture
MC_RENDER_STAGE_PARTICLES	All particle geometry
MC_RENDER_STAGE_CLOUDS	Vanilla cloud geometry
MC_RENDER_STAGE_RAIN_SNOW	Rain and snow geometry (not including particle effects)
MC_RENDER_STAGE_WORLD_BORDER	World border geometry
MC_RENDER_STAGE_HAND_TRANSLUCENT	Transparent geometry for held items/blocks
