That’s not exactly how it works. You have to create a copy of the character you’re trying to reflect. It doesn’t automatically do it on its own. Basically you need to upload a background with a whole in the place of a mirror. So it’s transparent in that spot. You’ll have to upload it as an overlay so you can layer it. Then you have to upload the mirror png you have as another overlay. Finally, you have to make a copy of the character you’re trying to mirror. Or object. It doesn’t reflect on its own.
I can send you the overlay you need sure, but you already have everything else you need.
Here it is: I compressed it so it fits the requirements. Remember to upload this and the mirror as separate overlays. That white part in the image is basically transparent, so you can layer it.
