Canvas not rendering in Game mode only

Hi.

I have a case where I try to render a World Space Canvas, that is created inside a SubScene, but up to now I completely failed to make it work.

My camera won't render my Canvas, but it will render any other entity correctly, or even Canvas that are outside of subscene. I tried to render it as GameObject with the "Conver to Entity (Stop)", but it didn't help

How to reproduce

Prepare standard scene

1. Create a new Scene (it will create a new Main Camera)
2. Add a new canvas to the scene
3. Set the canvas to World Space
   
4. Add a Panel to the canvas
   
5. Adjust the camera until you see the panel in camera view of the Scene View
   
6. Hit "Play" and Validate that we can see the Panel in Game mode
   
   • Select the camera and you will the panel render
     
   • Hit "Play" and you will the panel render
     
     

Now create the subscene

1. Right click the canvas in Hierarcy and then "New Sub Scene > From Selection"
2. Save the new subscene
3. Add "Convert To Entity (Stop)" on the canvas
4. Select the camera in Hierarchy and validate you still see the panel in camera view of the Scene View
   
5. 
   
6. Hit "Play" and enter Game Mode
   • PROBLEM: The Canvas (panel) do not render

Question

Any tips / ideas on how to fix?

Thank you!

 

This is Answer： https://docs.unity3d.com/Packages/com.unity.entities.graphics@1.0/changelog/CHANGELOG.html

• UI and Canvas components are not supported in subscene.

 

OP was using Entities 0.50.
Now 1.0 has changed a lot since.
Please do not necro post pointlessly.
Or at least link relevant information to Entities 0.50.

Either way subscene canvas didn't work then. Neither now.
