OVERRIDE_GLTF_BASE_COLOR_FACTOR

1

vector

Set the tinting color used for the base color. Color is specified in linear RGB. Use llsRGB2Linear to convert colors from BP to PBR.

OVERRIDE_GLTF_BASE_ALPHA

2

float

Sets the alpha for this face. Only impacts the rendering when alphamode is blend.

OVERRIDE_GLTF_BASE_ALPHA_MODE

3

integer

Set the alpha mode on the face. Must be one of the valid blend modes

GLTF Alpha Mode	value	description
PRIM_GLTF_ALPHA_MODE_OPAQUE	0	Ignore the alpha value and render the material as opaque.
PRIM_GLTF_ALPHA_MODE_BLEND	1	Render the material with transparency determined by the alpha value. Blending is done in linear color space. As is the case for Blinn-Phong as well, this mode suffers from depth sorting and performance issues. Use alpha mask instead when possible.
PRIM_GLTF_ALPHA_MODE_MASK	2	Render the material as fully opaque where the alpha value is greater than the alpha cutoff, and otherwise render the material as fully transparent.

OVERRIDE_GLTF_BASE_ALPHA_MASK

4

float

Sets the alpha cutoff level on this face when alpha mode is set to mask.

OVERRIDE_GLTF_BASE_DOUBLE_SIDED

5

integer

If set to TRUE then the texture on the specified face is considered double sided.

OVERRIDE_GLTF_METALLIC_FACTOR

6

float

Adjusts the metallic factor on the specified face.

OVERRIDE_GLTF_ROUGHNESS_FACTOR

7

float

Adjust the roughness factor on the specified faces.

OVERRIDE_GLTF_EMISSIVE_FACTOR

8

vector

Set the tint used for the emissive texture on this face.

Passing an empty string ("") as the override value will clear that override.
