Hi Guys is there any way we can customize model in runtime and then export the model in any format in runtime application

Hi @Jack,

There is a gltf exporter in the engine repo:

github.com

playcanvas/engine/blob/main/extras/exporters/gltf-exporter.js

import { CoreExporter } from "./core-exporter.js";
import {
    ADDRESS_CLAMP_TO_EDGE, ADDRESS_MIRRORED_REPEAT, ADDRESS_REPEAT,
    BLEND_NORMAL,
    CULLFACE_NONE,
    FILTER_NEAREST, FILTER_LINEAR, FILTER_NEAREST_MIPMAP_NEAREST, FILTER_LINEAR_MIPMAP_NEAREST,
    FILTER_NEAREST_MIPMAP_LINEAR, FILTER_LINEAR_MIPMAP_LINEAR,
    INDEXFORMAT_UINT8, INDEXFORMAT_UINT16, INDEXFORMAT_UINT32,
    PROJECTION_ORTHOGRAPHIC,
    SEMANTIC_POSITION, SEMANTIC_NORMAL, SEMANTIC_TANGENT, SEMANTIC_COLOR,
    SEMANTIC_BLENDINDICES, SEMANTIC_BLENDWEIGHT, SEMANTIC_TEXCOORD0,
    SEMANTIC_TEXCOORD1, SEMANTIC_TEXCOORD2, SEMANTIC_TEXCOORD3, SEMANTIC_TEXCOORD4,
