Is it possible to draw Gizmos (https://docs.unity3d.com/ScriptReference/Gizmos.html) in the scene view.. but overlaying the UGUI Canvas (within the scene view) and not particularly in world space? I'm looking to outline some UI elements in the scene view more fully than the vanilla Unity RectTransform is shown there.
We looked at using https://docs.unity3d.com/ScriptReference/Gizmos.DrawGUITexture.html but that appears to fall-back on old-style UI layout and doesn't account for the multiple different Render Modes the UI Canvas can be set to.
No.
You need to create the gizmos yourself in the game. There are some plugins in the asset store that provide re-implemented gizmos. You can have a look at them.
To show a 3D object in a texture, you need another camera and a RenderTexture asset. Let the camera look at the gizmos you created and assign the RenderTexture to Camera.targetTexture.
To show the texture on the UGUI Canvas, create a RawImage, then assign the RenderTexture to it.

My all project works in UI. One of my scene has videoPlayer and I would like to set my MainCamera to that specific Area. This scene is my Recording scene but for recording I have to use canvas Render Mode and has to be "Screen Space - Camera". How I can set my camera view to that specific area.
I tried 2nd camera with culling mask but didn't work because videoplayer is already my UI's child when camera Renders UI showing all children objects.
Is it possible show to camera whereever I want in UI?
enter image description here
Yessir it sure is. I literally had to do this a couple of days ago. Here is a tutorial/video I followed to figure out how to do it for my application. From the sounds of it, all you need to do is follow the video up to ~3 minutes. Then utilize the end product of getting a camera to showcase something in a UI window for your application.
For reference if the video gets deleted the process is as follows:
Create a new GameObject within the Canvas
Add a Raw Image as a child to to the new GameObject
We want a raw image because Raw Images in particular support the addition of a 2d Texture and this is what we need in order to display the Camera view.
Add a new Camera as a child to the GameObject
Create a new Render Texture in you Project Folder
Add the Render Texture to your Camera's Camera Component in the Target Texture field
Add the Render Texture to you Images Raw Image Component in the Texture field
Move the Camera to what you want to view and it should project to your UI GameObject.
If it doesn't do this correctly or the image has weird aspect ratios, check the dimensions in the Render Texture and your Image. It took me a while to get everything to look normal but it really just takes dimension adjustments.
Hope this helps!
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 like to play animation on a Canvas.
I made a canvas as shown in the following image.
I like to play a golfer animation on the green color canvas.
Is it possible?
I have animation model as shown in the second figure.
I like to play that golfer animation on the canvas.
How can I do that?
I drag and put under canvas as child object, it doesn't work.
As I explained in my comment, I would do as follow :
Put your object in a specific layer (called MyLayer for the sake of the example)
Set the Culling mask of a new camera to render only this specific layer
Uncheck the MyLayer in the Culling mask of your main camera in order to prevent the latter to render your model
Set the Clear flags to Depth only of the camera to prevent the latter from rendering the skybox
Create a new Render texture in your project, and drag & drop it in the Render Texture field of your new Camera
Add a new Raw Image to your UI canvas and assign the render texture in the Texture field
Run your 3D animation
Your camera will render the animation into the image on your UI
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.

I'm fairly new to Unity and I'm trying to embed a 3d view inside a 2d one.
I'm working on an emulation app that has a 2d UI for controls and a preview of the result in a 3d box that should be embedded in the 2d one, sort of as a player.
What's the right approach to doing that in Unity? Is there a way of "embedding" one scene in another?
Thanks!
If you want to create 3D effect with UI canvas, you should look to this link.
If you are using 2D project, it is basically 3D scene with camera set to use ortographic projection, not perspective. So you can use 3D models as well.
You should look into Render Texture. Those allows to render a camera view onto a texture in a scene. Say you have a part of a scene an dyou want to render onto a TV screen in your game. You would place the TV scene somewhere and place your camera to view it. Then you create a render texture and apply onto the mesh that is making your tv screen.
Now if you wish to make a UI system, like a radar with a top view, you would modify the viewport of your top view camera (0,0,.2,.2 would place it bottom left corner with 20% height and width) and make the depth higher so that it renders on top of the main camera.
