Render Camera to Texture in Unreal Engine

Camera feeds, car mirror, or whatever other weird ideas you have, sometimes you need to put the view of a camera onto another mesh as a texture. Unreal makes this really quick and easy to do! so let's take a look at the basic setup!

Very helpful. Thank.

I was looking for this.
Question: I have PCG that generates rooms (walls have x,y and rotation).
Can I use this to generate a world map that can change in real time?
Maybe not with a camera but with the X,U and rotation of each wall?
Can you give me an advice?
I was thinking of doing it somehow with widget and canvas but I don;t know

How would I go about controlling the camera

I am wondering if this could solve the mirror issue in unreal engine 5 and especially in 5.4 since the raytracing deprecated is not an option anymore. So basically to make a render camera to texture that moves perpendicular to the opposite direction of our view point

[@thegamedevcave]

that's more or less what planar reflections do (although its more optimized than using a camera to a texture I believe)

@@thegamedevcave yes but in that case I have to use screen space as GI right?
