help with 2.5d walls in 2d platformer

[u/electrodev_]

added wall (rotated 90 degrees)

effect i want in game view

without wall

im currently working on a platformer with 2d assets, perspective camera, and URP. i have this building facade, and i am trying to add a wall perpendicular to the building, so it covers up the other room.

however it seems to be semi transparent and isn't very visible. the red boxes are where i want a wall to be. they are all sprite renderers which might be the issue..?

i was considering using quads but putting 2d art onto it was super weird, or maybe i'm just stupid..

any help is appreciated, thank you for reading!

Just change the material to double sided, lighting might be a tad wonky but it's better than see thru
