Want to add a game mat

I have a pic of a rl game mat I own that I would like to add to game. Downloaded the customization but can’t figure out where to add the pic to set it as a game mat.

There isnt a place to set a game mat persay.
Your going to have to edit the backgrounds
“AppData\LocalLow\Duelists Unite\YGO Omega\Backgrounds”

and go from there.

You can use the TopView i posted for reference.

TopView default

ah ok, so you just have to kind of align it so your background looks like a game mat. Doable, harder, but very much doable.

Yes it’s very much doable.
It just takes a lot of time.

hm… the question is… should I give my opponent a game mat too or just leave as the background
