\qmlproperty RenderPass SubRenderPass::renderPass The RenderPass that will be executed as a sub-pass when this command is processed.
\qmltype SubRenderPass
\inherits Command
\inqmlmodule QtQuick3D
\brief Renders a sub-section of work within the same render target as the parent RenderPass.
\since 6.11
SubRenderPass is a \l Command that subdivides a \l RenderPass into
smaller, independently configured pieces while sharing the same render
target. Only the parent \l RenderPass controls which textures are
rendered into (via \l ColorAttachment and \l DepthTextureAttachment)
and when the pass begins (and therefore when the render target is
cleared). A SubRenderPass cannot set its own render target or clear
settings — those are always inherited from the parent pass.
What a SubRenderPass \e can control is \e what gets rendered and
\e how: it has its own \l{RenderPass::commands}{commands}, so it can
carry a \l RenderablesFilter to select a subset of objects, a
\l PipelineStateOverride to change depth/blend state, a different
\l{RenderPass::materialMode}{materialMode}, and so on.
A typical use is a forward-rendering pipeline where a single color
pass uses separate SubRenderPasses for the background, opaque
objects, and transparent objects. All three sub-passes write into the
same color and depth textures, but each has different pipeline state:
\qml
RenderPass {
id: mainColorPass
commands: [
Render targets are set at the parent RenderPass level only ColorAttachment { name: "color0"; target: colorTexture }, DepthTextureAttachment { target: depthTexture },
Sub-pass 1: render the skybox background SubRenderPass { renderPass: skyboxSubPass },
Sub-pass 2: opaque objects with depth testing and writing SubRenderPass { renderPass: opaqueSubPass },
Sub-pass 3: transparent objects with blending, no depth write SubRenderPass { renderPass: transparentSubPass } ] }
Sub-passes share mainColorPass's render target RenderPass { id: skyboxSubPass passMode: RenderPass.SkyboxPass }
RenderPass { id: opaqueSubPass commands: [ RenderablesFilter { renderableTypes: RenderablesFilter.Opaque } ] }
RenderPass { id: transparentSubPass commands: [ RenderablesFilter { renderableTypes: RenderablesFilter.Transparent }, PipelineStateOverride { blendEnabled: true depthWriteEnabled: false } ] } \endqml
