depthWrite not working

[Memolestas]

I have two planegeometries each with a meshbasicmaterial with depthWrite= false and renderDepth=0 but the two objects still render like usual, I want them to be on the background

this is a bug

If it's a bug you should still follow the guidelines and provide the details we ask for. A test case on jsfiddle is a must.

I've confirmed that setting depthWrite to true will have no effect if depthTest is false.
try flipping the depthTest value in material, below.

            maskedPlaneGeo = new THREE.PlaneGeometry( 10,10, 1, 1 );
            planeMat = new THREE.MeshBasicMaterial();
            planeMat.depthTest = true;
            planeMat.depthWrite = false;
            planeMat.transparent = true;
            planeMesh = new THREE.Mesh( maskedPlaneGeo, planeMat );
            planeMesh.rotation.setZ(3.14159 / 4);
            planeMesh.position.setZ(-10.1);
            planeMesh.renderDepth = -2;
            // Mask
            maskGeometry = new THREE.PlaneGeometry( 14.14,10, 1, 1 );
            material = new THREE.ShaderMaterial(DepthMaskShader);
            material.transparent = true;
            material.depthTest = true;
            material.depthWrite = true;
            material.alphaTest = false;

            mesh = new THREE.Mesh( maskGeometry, material);
            mesh.position.setY(-5);
            mesh.position.setZ(-10);
            mesh.renderDepth = -1;
            scene.add( mesh );
            scene.add( planeMesh );

jsfiddle please?
