Qt3D: Do I need to re-enable the state ( ColorMask for example) in next RenderPass?

sprhawk

I need multiple pass rendering,
In first pass I set the stencil buffer, the second I draw color buffer with stencil test.

renderPasses: [
                RenderPass {
                    shaderProgram: clipShader
                    renderStates: [
                        ClipPlane { planeIndex: 0 },
                        ColorMask {
                            alphaMasked: false
                            redMasked: false
                            blueMasked: false
                            greenMasked: false
                        },
                        CullFace {
                            mode: CullFace.NoCulling
                        },

                        StencilTest {
                            back.stencilFunction:StencilTestArguments.Always
                            back.referenceValue: 0
                            back.comparisonMask: 0xff
                            front.stencilFunction: StencilTestArguments.Always
                            front.referenceValue: 0
                            front.comparisonMask: 0xff
                        },
                        StencilOperation {
                            back.allTestsPassOperation: StencilOperationArguments.DecrementWrap
                            back.stencilTestFailureOperation: StencilOperationArguments.Keep
                            back.depthTestFailureOperation: StencilOperationArguments.Keep
                            front.allTestsPassOperation: StencilOperationArguments.IncrementWrap
                            front.stencilTestFailureOperation: StencilOperationArguments.Keep
                            front.depthTestFailureOperation: StencilOperationArguments.Keep
                        }
                    ]
                },
                RenderPass {
                    shaderProgram: clipShader
                    renderStates: [
                        ClipPlane { planeIndex: 0 },
                        // If I comment out ColorMask, nothing is drawn
                        ColorMask {},
                        CullFace {
                            mode: CullFace.Front
                        },

                        StencilTest {
                            back.stencilFunction:StencilTestArguments.Equal
                            back.referenceValue: 1
                            back.comparisonMask: 0xff
                            front.stencilFunction: StencilTestArguments.Equal
                            front.referenceValue: 1
                            front.comparisonMask: 0xff
                        },
                        StencilOperation {
                            back.allTestsPassOperation: StencilOperationArguments.Keep
                            back.stencilTestFailureOperation: StencilOperationArguments.Keep
                            back.depthTestFailureOperation: StencilOperationArguments.Keep
                            front.allTestsPassOperation: StencilOperationArguments.Keep
                            front.stencilTestFailureOperation: StencilOperationArguments.Keep
                            front.depthTestFailureOperation: StencilOperationArguments.Keep
                        }

                    ]
                }

In the second RenderPass I must specify a ColorMask, or else nothing will be drawn.

So during the render passes, the all the RenderStates are all kept along ?

( Shouldn't each render pass have its own render state? )
