Strange artifacts on reflections

Hi everyone! Just a quick one, here´s an image of the scene I’m working on:


Weirdly enough, on the reflection of that mirror I can see a background with cars and trees. There’s no such background on my scene, so I suppose they come from some type of hdr or something similar… which I don’t have in my scene… So strange.

Any clues to why this might be happening?

Thanks for your time!

That looks like the default epic HDR texture (from their carpark, oddly enough).

Check the skylight in your level, and make sure you don’t have a HDR cubemap plugged in.
