Sophie's Zombies Prototype

Hi, This is a fun little project I'm working on that is made within unity.

I first started working on this project as a kinda like Call of Duty Zombies like game.
(wave based arena style zombie survive till you die)

But it's starting to evolve from that into a full fledged zombie survival game.

WARNING: This game is marked as "Pre-Pre-Alpha" (Alpha Alpha) For a reason; This game is in the boxiung out/prototyping stage, the graphics will look quite bad, and I'm mostly using placeholder assets for models,

ASSETS WILL CHANGE.
SOUND WILL CHANGE.
MODELS WILL CHANGE
VISUALS COULD CHANGE
THIS IS A PRE-PRE ALPHA, BASSICALLY JUST A CONCEPT, IT WAS A WAVE CONCEPT AND A SURVIVAL CONCEPT, DO NOT EXPECT THIS TO BE A FULL GAME;

HELP:

I keep getting this error in survival mode <error>:

iof it's a "nullreferance" about buttons then just open the inventory, that error happense when the game tries to referance the players inventory without it being opened, idk what causes it exactly yet esp sense it's only in survival mode

How do I change the Graphics/Turn off Ray tracing?

OPEN THE CONSOLE BY PRESSING THE TELDE (~) KEY
then type the following as wanted.

SetRaytracingPreset <Preset ID> Takes any int between 0 and 5

SetGraphicsPreset <Preset ID> Takes any int from 0 to 4

DLSS,SetQuality <Quality> 0 to 3

Is there a way to spawn enemies/weapons/objects?:

Yes open console and do SpawnItem ItemID 
I do not know all the item ID's as I autogenerate them, try stuff out. I believe 8 should be a gun though?
