Played with those location values a little more and got the SceneCaptureComponent2D to line up perfectly with the player camera, so that part is now good.
New problem has shown up. Strafing side by side makes object in the RenderTexture looks blurry for some reason. In the video, the blurriness is most noticeable if you look at the specular spot on the far sphere. Any ideas on what is causing this?
Video is here…
I added some spheres that only show up in the RenderTexture for fun.
