```auto
// Create MRT
const mrt = new MultiRenderTarget('', {
    width: 100, height: 100 
}, 3, scene, {
    generateDepthBuffer: true,
    generateStencilBuffer: true,
    defaultType: Engine.TEXTURETYPE_FLOAT,
});

// Render to MRT
scene.customRenderTargets.push(mrt);

// ... render stuff to MRT ...

// Switch back to defaultframebuffer
scene.customRenderTargets = [];

// Before diposing MRT..., i want to
// read its depth buffer then write to defaultframebuffer
// ?? how ??

```

thanks. 😵

You can get the array of textures with:

`mrt.textures`

If you enabled depth, you can use `mrt.depthTexture` to get the depth texture.
