llSetLinkGLTFOverrides

function

Function syntax

llSetLinkGLTFOverrides(

integer link,// Link number (1 for root, >1 for children) or a LINK_* flag. Values: Links
integer face,// Face number or ALL_SIDES. Values: Faces
list params// A list of overrides and their corresponding values to set.

);

Energy: 10

Sets or removes individual GLTF override parameters specified by params on face of the linked prim link.

Sets or removes individual overrides applied to a PBR texture on a face

llSetLinkGLTFOverrides(0, 0, []);

Specification

From the LSL definitions: GLTFOverride (rule, then its arguments)

// Colour and alphaOVERRIDE_GLTF_BASE_COLOR_FACTOR, vector  // base colour tint, linear RGB (llsRGB2Linear)OVERRIDE_GLTF_BASE_ALPHA, float  // used only with PRIM_GLTF_ALPHA_MODE_BLENDOVERRIDE_GLTF_BASE_ALPHA_MODE, integer  // PRIM_GLTF_ALPHA_MODE_*OVERRIDE_GLTF_BASE_ALPHA_MASK, float  // alpha cutoff for _MASK// SurfaceOVERRIDE_GLTF_METALLIC_FACTOR, float  // 0 to 1OVERRIDE_GLTF_ROUGHNESS_FACTOR, float  // 0 to 1OVERRIDE_GLTF_EMISSIVE_FACTOR, vector  // emissive tint, linear RGBOVERRIDE_GLTF_BASE_DOUBLE_SIDED, integer  // TRUE renders both sides

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

Caveats

OVERRIDE_GLTF_BASE_COLOR_FACTOR and OVERRIDE_GLTF_BASE_ALPHA parameters are coupled. If an override is set for one parameter, then the other is automatically given an override. The default OVERRIDE_GLTF_BASE_COLOR_FACTOR is <1,1,1>, and the default OVERRIDE_GLTF_BASE_ALPHA is 1.0.

Examples

Toggle alpha on\off

integer toggle;
default
{
    touch_start(integer num_detected)
    {
        toggle=!toggle;
        llSetLinkGLTFOverrides( LINK_THIS, 0, [
            OVERRIDE_GLTF_BASE_ALPHA_MODE, PRIM_GLTF_ALPHA_MODE_BLEND,
            OVERRIDE_GLTF_BASE_ALPHA, toggle]);
    }
}
