World-Space RenderTargets

Duelist Render Target
The fastest way to put Rive content on a mesh in world space is to use a Rive RenderTarget asset. You can drag a Rive RenderTarget directly into the level. Unreal will:
  • Spawn an actor in the scene
  • Create a material that displays the RenderTarget texture
  • Assign the material to the spawned mesh
This workflow is ideal for:
  • In-world screens
  • Monitors / kiosks
  • Control panels
  • “TV” surfaces
This page covers world-space RenderTargets.
For screen-space UI (HUDs/menus), use URiveWidget.

​
1) Create a Rive RenderTarget asset

  1. Rigt-click on a Rive file asset.
  2. Select Create Rive Render Target.
Double clicking the created RenderTarget will open the asset editor in which you can specify:
  • Rive File
  • Artboard
  • State Machine (optional)
  • Size / Resolution
Start with 512×512. Increase only if the screen is large and close to the camera.

​
2) Drag it into the Level

Drag the RenderTarget from the Content Browser into the viewport to apply it to a mesh. Unreal will automatically create a material that samples the RenderTarget texture. At this point you should see the Rive content on the surface.

​
3) How updates work (Tick + Draw)

A RenderTarget is a texture output. It only changes when the runtime is advanced and drawn. In practice, you must ensure there is a driver in your scene that:
  • Advances the runtime (Tick)
  • Draws the frame into the RenderTarget (Draw)
If nothing is driving the RenderTarget, it will appear static.
The recommended driver for RenderTargets is RiveRenderTargetUpdater, which is designed specifically for in-world textures.

​
4) Driving the RenderTarget with RiveRenderTargetUpdater

If you are using the RenderTarget workflow, place an Actor in the level that owns the runtime and renders to the target. Typical setup:
  1. Create an Actor Blueprint (e.g. BP_RiveRenderDriver)
  2. Add a RiveRenderTargetUpdater component.
  3. Point it at the RenderTarget in the details pane.
  4. Set the RenderTarget size to match your in-world material needs.
RiveRenderTargetUpdater is intended for RenderTargets (world-space textures).
It is not intended for screen-space widgets.

​
5) Interactivity

If your Rive content is interactive (state machine + view model):
  • Bind a ViewModel
  • Set ViewModel values
  • Fire triggers
The RenderTarget will reflect changes the next time it is driven (tick/draw).
