float Ogre::CompositorPassDef::mClearDepth
inherited

◆ mClearStencil

uint32 Ogre::CompositorPassDef::mClearStencil
inherited

◆ mColourWrite

bool Ogre::CompositorPassDef::mColourWrite
inherited

When false will not really bind the RenderTarget for rendering and use a null colour buffer instead.

Useful for depth prepass, or if the RTT is actually an UAV. Some passes may ignore this setting (e.g. Clear passes)

◆ mExecutionMask

uint8 Ogre::CompositorPassDef::mExecutionMask
inherited

◆ mExposedTextures

IdStringVec Ogre::CompositorPassDef::mExposedTextures
inherited

◆ mFlushCommandBuffers

bool Ogre::CompositorPassDef::mFlushCommandBuffers
inherited

Whether to flush the command buffer at the end of the pass.

This can incur in a performance overhead (see OpenGL's glFlush and D3D11' ID3D11DeviceContext::Flush) for info. Usually you want to leave this off. However for VR applications that must meet VSync, profiling may show your workload benefits from submitting earlier so the GPU can start right away executing rendering commands.

The main reason to use this is in CPU-bound scenarios where the GPU starts too late after sitting idle.

◆ mIdentifier

uint32 Ogre::CompositorPassDef::mIdentifier
inherited

Custom value in case there's a listener attached (to identify the pass)

◆ mIncludeOverlays

bool Ogre::CompositorPassDef::mIncludeOverlays
inherited

TODO: Refactor OgreOverlay to remove this design atrocity.

A custom overlay pass is a better alternative (or just use their own RQ)

◆ mJobName

IdString Ogre::CompositorPassComputeDef::mJobName

Name of the HlmsComputeJob to run.

inherited

◆ mReadOnlyStencil

bool Ogre::CompositorPassDef::mReadOnlyStencil
inherited

◆ mShadowMapFullViewport

bool Ogre::CompositorPassDef::mShadowMapFullViewport
inherited

Only used if mShadowMapIdx is valid (if pass is owned by Shadow Nodes).

If true, we won't force the viewport to fit the region of the UV atlas on the texture, and respect mVp* settings instead.

◆ mShadowMapIdx

uint32 Ogre::CompositorPassDef::mShadowMapIdx
inherited

Shadow map index it belongs to (only filled in passes owned by Shadow Nodes)

◆ mStoreActionColour

StoreAction::StoreAction Ogre::CompositorPassDef::mStoreActionColour[OGRE_MAX_MULTIPLE_RENDER_TARGETS]

◆ mViewportModifierMask

uint8 Ogre::CompositorPassDef::mViewportModifierMask
inherited

◆ mVpRect

ViewportRect Ogre::CompositorPassDef::mVpRect[16]
inherited

Viewport's region to draw.

◆ mWarnIfRtvWasFlushed

bool Ogre::CompositorPassDef::mWarnIfRtvWasFlushed
inherited

Will issue a warning (by raising an exception) if Ogre is forced to flush the RenderTarget, which is very bad for performance on mobile, and can cause serious performance problems in Desktop if using MSAA, and also cause correctness problems (i.e.

bad rendering) if store action is StoreAction::Resolve.

Remarks
Flushes are caused by splitting rendering to the same RenderTarget in multiple passes while rendering to a different RenderTarget in the middle. It's not always possible to avoid it, but if so, consider doing it.
No warning will be issued if the RenderTargets getting flushed have their LoadAction set to LoadAction::Clear (or LoadAction::ClearOnTilers on tilers).
