you lacking a bit of technical comprehension?
the scene capture has it’s own postprocess settings. (ignore the bp attempt to project it. i’m not good at it.)
it’s basicly re-rendering an entire scene into a render target. it’s like a viewport render. in this case of a cube map capture, it will render 6 scenes. 1 for every cube face. and… the way your blueprint is setup it will still render every frame cause i assume you didn’t untick render on movement. that means… it will render on movement. and… you’re moving the capture location every frame.
