Syntax

virtual bool DoesSupportLateUpdate() const

Remarks

Return true if the default camera implementation should query the current pose at the start of the render frame and apply late update. In order to support late update, the plugin should refresh the current pose just before rendering starts. A good point to insert the update is in OnBeginRendering_GameThread or OnBeginRendering_RenderThread.

that for backwards compatibility with plugins written before 4.19, this method defaults to returning 'true'
