Hi Sophie! Thanks for the comment! There's no exterior asset yet, but it will be published and daily updated when we hit the end of this pack (400th daily update) ;)
Hi Sophie, the 3D walls aren't actually compatible with the MV, but I'll do some more test asap! For now, there are tons of classic walls compatible, you can find them in the MV folder ("Modern_Interiors" -> "5_RPG_Makers")!
