RenderTexture not showing UI elements

Question

I want to take a screentshot from UI elements inside a canvas in screen space-overlay render mode. So I added a renderTexture to the main camera. If I change the render mode to World Space then UI elements show up. What is happening and why the UI layer is not being rendered by camera in space-overlay?

Found the issue: https://issuetracker.unity3d.com/issues/rendertextures-do-not-include-canvas-ui-elements It is intended to do that by design. To solve this you have to call Render before taking the screenshot so UI is forced draw.

 Camera.main.renderTexture = myRenderTexture;
 Camera.main.Render();
 Caemra.main.renderTexture = null;

so it forces to render the UI layer.

There is not .renderTexture member. Did you mean targetTexture? In any case I added this code to my main camera in the Update() it the UI does not render in ScreenSpace-Overly mode.... It only renders in ScreenSpace-Camera mode, even without this code by attaching the renderTexture to the camera using there targetTexture slot.

Are you sure it worked for ScreensSpace-Overlay?

Yes I have this problem too. In screen space overlay camera can not show ui elements dynamically neither statically. I'm still searching for a solution.

render texture is designed render the elements that has depth, so screen space overlay elements does not write in the depth buffer unlike world space and screens pace - camera.
