A material to create or edit in the material library. name keys the material; every other field is optional and only the set ones are written, so editing leaves untouched fields (including textures) intact.

Fields

name: String

base_color: Option<[f32; 4]>

Linear RGBA albedo.

metallic: Option<f32>

roughness: Option<f32>

emissive_factor: Option<[f32; 3]>

emissive_strength: Option<f32>

unlit: Option<bool>

double_sided: Option<bool>

base_texture: Option<String>

Name of an already-loaded texture for the base-color map. Built-in prototype textures are always available: “proto_light”, “proto_dark”, “proto_green”, “proto_orange”, “proto_purple”, “proto_red” (grid greybox textures).

tiling: Option<f32>

How many times the base texture repeats across a surface. Higher tiles the pattern more finely; set it near a surface’s size in units (e.g. 6 for a 6-unit wall) so a greybox grid reads as roughly one cell per unit. Applied when a base_texture is set; defaults to a small value.

normal_texture: Option<String>

Name of an already-loaded texture for the normal map.

normal_scale: Option<f32>

Normal map intensity multiplier (1 is full strength).

metallic_roughness_texture: Option<String>

Name of an already-loaded texture for the metallic (B) / roughness (G) map.

emissive_texture: Option<String>

Name of an already-loaded texture for the emissive map.

occlusion_texture: Option<String>

Name of an already-loaded texture for the ambient-occlusion (R) map.

occlusion_strength: Option<f32>

Occlusion effect strength (0 none, 1 full).

alpha_mode: Option<String>

Transparency handling: one of “Opaque”, “Mask”, “Blend”.

alpha_cutoff: Option<f32>

Alpha threshold for the “Mask” alpha mode.
