Template:LSL Constants/GLTF Overrides

Parameters

parameter	value	type	description
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.
