WebGLMultisampleRenderTarget not support DepthTexture ?

var depthTexture = new THREE.DepthTexture();
var parameters = {
format: THREE.RGBFormat,
stencilBuffer: false,
depthBuffer: true,
depthTexture: depthTexture
};

var size = renderer.getDrawingBufferSize( new THREE.Vector2() );
var renderTarget = new THREE.WebGLMultisampleRenderTarget( size.width, size.height, parameters );

output error:
[.WebGL-0x7fcad880e800]GL ERROR :GL_INVALID_OPERATION : glBufferData: <- error from previous GL command

No, this use case is not supported so far. Just the basic setup. It’s also not possible use a multisampled WebGLRenderTargetCube. You can file a feature request at github so it’s easier for the project to track these open tasks.
