Missing Pixel with obj file

[edisonlao]

Hello，Thank you for reading this issue
i found that missing pixel when i use GLModelView to load .obj+.mtl file,
any solution has not been found yet

react-native 0.61.3
react-native-gl-model-view 1.6.0
android 10

Expected

render complete like windows10 3DViewer

show on windows10 3DViewer:

show on Android GLModelView:

code:

<AnimatedModelView 
    model={{uri: 'man.obj'}}
    texture={{uri: 'man_skin.png'}}
    onStartShouldSetResponder={() => true}
    onResponderRelease={this.onMoveEnd}
    onResponderMove={this.onMove}
    animate={!!fromXY}
    tint={{r: 1.0, g: 1.0, b: 1.0, a: 1.0}}
    scale={0.1}
    rotateX={rotateX}
    rotateZ={rotateZ}
    translateZ={-10}
    style={styles.container}
/>

Personal guess

the .obj and.mtl file are not interguided properly

i'm tried to modify setModelUri() and loadModelFromInputStream() method in RNGLModelView.java but it didn't work

setModelUri() method:
 if (pUri.startsWith(lGeometryHeader)) {
      final String lBase64 = pUri.substring(lGeometryHeader.length());
      final InputStream lInputStream = getInputStreamFromBase64(lBase64);
          
      +InputStream mtlInputStream = null;
      +if(pUri.endsWith(".obj")){
        +String pMtl = pUri.replace(".obj", ".mtl");
        +final String mtlHeader = RNGLModelView.getBase64EncodedGeometryHeader("mtl");
        +final String mtlBase64 = pMtl.substring(mtlHeader.length());
        +mtlInputStream = getInputStreamFromBase64(mtlBase64);
      +}
          
      -model = RNGLModelView.loadModelFromInputStream(lInputStream, lGeometryType);
      +model = RNGLModelView.loadModelFromInputStream(lInputStream, mtlInputStream, lGeometryType);
 }

loadModelFromInputStream() method :
switch (pExtension) {
      case "obj":
        -return Object3D.mergeAll(Loader.loadOBJ(pInputStream, null, 1));
        +return Object3D.mergeAll(Loader.loadOBJ(pInputStream, mtlStream, 1));
      case "3ds":
        return Object3D.mergeAll(Loader.load3DS(pInputStream, 1));
      case "md2":
        return Loader.loadMD2(pInputStream, 1);
      case "asc":
        return Loader.loadASC(pInputStream, 1, false);
      case "model":
        return RNGLModelViewModelLoader.loadMODEL(pInputStream);
    }
