I'm using a canvas to show InformationText on the screen. This works perfectly fine. However, when I try to put a 3D object in my canvas, it doesn't show. Can somebody tell me why?
I'm using Unity 2019.2.12f1
My canvas:
My Main Camera:
My MarkerModel
The Game
I added a camera to my 3D-object. This fixed the problem for me!
Set canvas to world space
and put canvas near your 3D object and move camera to make object and canvas visible

I am new to Unity and am working on a UI project. I want to add a Camera targeted on a GameObject in the Canvas. There is a Camera with the same hierarchy of the Canvas and when I clicked it the preview is blank but when I play the project everything is shown, including all the buttons texts images.
How does the Camera work with UI and is it possible to add a camera targeted on a GameObject?
For your main Canvas, you do not need a Camera. Please see the Unity Manual for information regarding the Canvas. Take note of the Render Mode option on the Canvas Component. If this is set to Screen Space - Overlay then you will not need a camera to view UI Items or GameObjects that are placed as children to this GameObject. It will also inherently not appear in your Camera Preview if it is located under a Canvas of this type.
If you would like to have other GameObjects show up in the Camera Preview, add them to your scene and ensure that they are not under the Canvas GameObject. Then ensure that they are in range of your Camera.
Hope this helps!
I have a basic scene with 3 prefabs from the HoloToolkit-Unity package:
HololensCamera + InputManager + CursorWithFeedback
I then add a Canvas (and subsequently a Panel and a Button) to my scene, with the Canvas being in Screen Space - Camera and the HololensCamera being the Render Camera and of course everything was fine, until I noticed that when I run on device, the cube is there as a fixed game object (as one would expect!) but my whole Canvas seems like it is attached to the camera.
Why is this? How do I place a fixed Canvas in my scene?
Read through this
https://docs.unity3d.com/Manual/UICanvas.html
Notice the differences between Overlay/Screenspace/Worldspace
And also try to understand the relation between different camera's and UI elements. If afterwards you still don't understand i'll try to help you.
This is my first time with unity, I need to make a 3d object in the camera of the device (vr) in certain coordinates of a map, do you know any links that can help me? Is only a static object will always be in the same position and users will be able to see it on their devices
If this is to be overlayed above a 3D scene use a renderTexture, then add the rendered texture to the UI using a Raw Image component.
Another way to do this is to use a canvas set to screen space overlay rendering. You can create a canvas by going to GameObject > UI > Image.
(see page for UI>canvas on Unity manual site, I can only post 2 links as a new user)
The canvas in this rendering mode is described this way on the unity manual page for the UI Canvas:
Screen Space - Overlay
This render mode places UI elements on the screen rendered on top of the scene. If the screen is resized or changes resolution, the Canvas will automatically change size to match this.
I am assuming this is a UI element over a 3D scene, because you mentioned VR.
Credit: I got some of my links and info from the unity forum thread "What is the best way to display 3D models as UI elements?"
Is there a way to render a sprite in just one eye, while it is invisible through the other eye? Any help would be appreciated.
Thanks
I have this setup and this renders a single canvas stretched on the whole screen on top of the eyes:
Edit: I'm using Google Cardboard SDK but the principle should be all the same
Currently there is no documentation whatsoever on how to make a "visor" HUD on Unity for a Cardboard game. Screen Space - Overlay does not work as rendering mode as many people have already said. Does anyone know of a workaround/method for making it using World Space rendering?
You must create your HUD in a World Space canvas, put it in front of the camera and attach it to the Head object of the Cardboard SDK. That way it will be always visible in front of the player.
