UMjCameraFeedEntry¶

UMG widget row that binds to a single UMjCamera and displays its live feed.

Its Blueprint counterpart (WBP_MjCameraFeedEntry) must contain: - UTextBlock "CameraNameText" — displays MjCamera::MjName - UImage "FeedImage" — shows the render target via a UMaterialInstanceDynamic Usage: UMjCameraFeedEntry* Entry = CreateWidget(..., CameraFeedEntryClass); Entry->BindToCamera(Cam); MyVerticalBox->AddChildToVerticalBox(Entry); The owning widget should call UpdateFeed() each tick and UnbindCamera() before switching the articulation selection, so streaming is cleanly disabled on old cameras.
