SRB2 Kart Level Tutorial Using Zone Builder?

[ThatOneGamingDude // T1GD]

Okay, I'm not a really good sprite artist, so I thought I'd make a racetrack. One problem, though. When I went to make a map, I saw a bunch of errors that a bunch of textures weren't loaded.

I'd like to make this level and I don't feel like a) reading the Standard SRB2 tutorial, or b) joining a Discord. Can anyone walk me through this?
