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 Blinn-Phong to PBR.
OVERRIDE_GLTF_BASE_ALPHA	2	float	Sets the alpha for the face(s). Only impacts the rendering when the alpha mode is set to PRIM_GLTF_ALPHA_MODE_BLEND.
OVERRIDE_GLTF_BASE_ALPHA_MODE	3	integer	Set the alpha mode on the face(s). 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 the face(s) when alpha mode is set to mask.
OVERRIDE_GLTF_BASE_DOUBLE_SIDED	5	integer	If set to TRUE then the texture on the face(s) will be rendered as double sided.
OVERRIDE_GLTF_METALLIC_FACTOR	6	float	Adjusts the metallic factor on the specified face(s). Value should be between 0 and 1.
OVERRIDE_GLTF_ROUGHNESS_FACTOR	7	float	Adjust the roughness factor on the specified face(s). Value should be between 0 and 1.
OVERRIDE_GLTF_EMISSIVE_FACTOR	8	vector	Set the tint used for the emissive texture on the face(s). Note that this is specified in linear RGB.

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