I'd like to create a portal-like effect using Bevy. It seems Unity has a render texture to achieve that.
Is there a way to do the equivalent in Bevy? If not, is there a plan to support that in the future?
This has become very easy with Bevy 0.8's Camera Driven Rendering
You simply assign an image render target to a camera:
camera.target = RenderTarget::Image(image_handle);
For a complete example see the official render to texture example.
