Reference / Nodes

3D Materials

Eight nodes that produce a material output. One, pbrMaterial, exposes the underlying live MSL editor. Six are baked presets that instantiate the same underlying node with a preset shader source. hdri is the environment-map node consumed for IBL.

Wire any material output into the material port of a geometry node. The preset materials all support live editing , open the inspector and rewrite the source any time.

PBR Material

pbrMaterial3D / Material

Live-editable Metal shading language material. Write or paste MSL into the inspector; ports are auto-derived from @input directives in the source.

Inputs

Port	Type	Default	Range	Notes
(declared via @input)	float	,	,	Ports are generated from @input directives at the top of the shader source.

Outputs

The inspector hosts a live MSL editor. Each line starting with // @input declares a port and its default value; types are color, float or texture. The body of the shader writes to albedo, metallic, roughness and emission.

Recompiles happen as you type. Compile errors land on the inspector; the previous successfully-compiled material keeps rendering until you fix the source.

HDRI

hdri3D / Material

Loads an HDR or LDR equirectangular panorama and exposes it as the scene's environment / IBL source.

Inputs

Port	Type	Default	Range	Notes
intensity	float	1	,	Multiplier on the environment irradiance.

Outputs

Port	Type	Default	Range	Notes
environment	texture	,	,

Pick the file on the inspector, .hdr, .exr and standard LDR formats all work. The panorama drives image-based lighting on every PBR material in the scene and is sampled as the skybox in the deferred renderer.

Without an HDRI, materials fall back to a flat ambient term, they look correct but lack the reflective context that sells PBR. A 1k or 2k HDRI is enough; bigger files cost more memory without much visible gain.

Chrome Mirror

chromeMirror3d3D / Material

Polished chrome preset, fully metallic, very low roughness, neutral tint.

Inputs

Port	Type	Default	Range
baseColor	color	0.95, 0.95, 0.96, 1	,
metalness	float	1	,
rough	float	0.04	,
tintColor	color	1.0, 0.95, 0.9, 1	,
tintAmount	float	0.1	,

Outputs

Port	Type	Default	Range	Notes
material	material	,	,

The default reflective look. With a good HDRI, this preset alone carries most product-shot compositions.

Gold

gold3d3D / Material

Brushed gold with view-dependent tarnish in the recessed areas.

Inputs

Port	Type	Default	Range
baseColor	color	1.0, 0.78, 0.34, 1	,
metalness	float	1	,
rough	float	0.25	,
tarnish	float	0.1	,
tarnishTint	color	0.35, 0.22, 0.08, 1	,

Outputs

Port	Type	Default	Range	Notes

Steel

steel3d3D / Material

Brushed steel, anisotropic-feeling banded roughness driven by UV.y.

Inputs

Port	Type	Default	Range
baseColor	color	0.56, 0.57, 0.58, 1	,
metalness	float	1	,
rough	float	0.35	,
brushing	float	0.6	,

Outputs

Glass

glass3d3D / Material

Dielectric glass with iridescent fresnel rim.

Inputs

Port	Type	Default	Range
tintColor	color	0.85, 0.95, 1.0, 1	,
rough	float	0.05	,
iridescence	float	0.6	,
opacity	float	0.25	,

Outputs

Port	Type	Default	Range	Notes
material	material	,	,

Not metallic, fresnel response drives the visible glass effect. On a torus or a sphere, the rim picks up rainbow shimmer that intensifies with iridescence.

Velvet

velvet3d3D / Material

Velvet cloth, sheen builds toward the silhouette like real fabric.

Inputs

Port	Type	Default	Range
baseColor	color	0.45, 0.05, 0.12, 1	,
sheenColor	color	1.0, 0.6, 0.3, 1	,
sheenPower	float	3	,
sheenAmount	float	1.2	,

Outputs

Port	Type	Default	Range	Notes

Neon

neon3d3D / Material

Emissive neon, bright color with an animated pulse, designed to interact with bloom.

Inputs

Port	Type	Default	Range
emissionColor	color	1.0, 0.25, 0.6, 1	,
glowStrength	float	4	,
pulseSpeed	float	3	,

Outputs

Port	Type	Default	Range	Notes
material	material	,	,

Bake into text3d for a sign-painter look, or onto a torus3d for a glowing ring. Make sure bloom is enabled on the scene3d composer or the emissive will only contribute color, not glow.
