Summary#

Materials must specify surface coating

Description#

Materials bound to geometry prims with computed purpose “render” or “default” must have a non-visual material coating property assigned to specify any surface treatment that affects non-visual sensor response.

Why is it required?#

  • Surface coatings modify sensor response characteristics

  • Required for accurate sensor simulation by providing additional material variations that would otherwise be absent with just the base material.

  • Affects reflection and absorption properties by treating the coatings as a layer deposited on the base material substrate.

Examples#

# Invalid: No coating specified
def Material "BadMaterial" (
    prepend apiSchemas = ["MaterialBindingAPI"]
)
{
    token omni:simready:nonvisual:base = "aluminum"
}

# Valid: Coating specified
def Material "GoodMaterial" (
    prepend apiSchemas = ["MaterialBindingAPI"]
)
{
    token omni:simready:nonvisual:base = "aluminum"
    token omni:simready:nonvisual:coating = "clearcoat"
}

How to comply#

  • Set omni:simready:nonvisual:coating on materials

  • Use valid coating types:

    • none

    • paint

    • clearcoat

    • paint_clearcoat
