meshSecondPass doesn't combine meshFirstPass in VR (HMD)

[zhudongwork]

I try to render the volume in my HMD with WebVR.js .
I set the renderer.vr.enabled = true ; document.body.appendChild( WEBVR.createButton( renderer ) ); renderer.setAnimationLoop( render );
When I enter the VR enviroment, I just can see the full color box. I can't see the texture.
When I look up my HMD, I can see the texture, but it's opposite to the direction of my head movement and the texture does not match the box. It seems that the texture and the box are separated.
