three.js - THREE.StereoEffect / webVR-boilerplate + THREE.Mirror

Question

I\'m trying to get a mirror effect working correctly in a project that is using webvr-boilerplate when VREffect is active.

I tried (using r72dev and r72) to use THR

This answer is based on the code in your live example, not the code in your post.

The problem is that StereoEffect calls renderer.clear(), but it is clearing the mirror's previously-rendered WebGLRenderTarget.

One solution is to do something like the following:

verticalMirror.render();

renderer.setRenderTarget( null ); // add this line

effect.render( scene, camera );
