Materials and Shaders

UNodeMaterial (2D)

Important fields include:

• fill color
• border color
• size
• corner radius
• clip rectangle data

UNodeMaterial3d

The 3D path adds PBR-related properties:

• metallic
• roughness
• emissive

2D Shader

In unode.wgsl:

• the base shape is evaluated as an SDF
• body and border masks are computed
• if use_clip = 1, the clip mask is applied before final color output

3D Shader

In unode_3d.wgsl:

• the same SDF shape logic is used
• the result is integrated into the 3D pipeline
