How to render scene to texture for display in Imgui widget?

[michaelaeriksen]

I would like to render the scene to a texture and then display that in an ImGui widget (scene widget). I have looked at various examples especially the vsgrendertotexture, but it's a bit too complicated for me to understand and modify for me to get a texture id I can use with ImGui. Any help or pointers would be appreciated.

Something like this, but where the scene is rendered in the Scene widget
