Im pretty much done with a head I was working on. It was a quickly to test things out. Can I just sell it without displaying it on tori just by showing the square image. Because as of now I can't put it on my tori and screenshot it to display it on the market. So can I just display the square image. Or maybe is there a way to put the head texture on uke without having to load a 512 head on my own Tori?

Head over here if you have any questions market-related.

Answering to your question, you must have at least one preview of the texture you're selling.

Ingame texture or just the square picture?

You can display the flat, that's fine, but you might want to watermark it as so no one
can steal it.

Someone could ask you the ingame pic, to see how it is the image on a sphere.

" At least 1 preview with toribash' default shader should be provided"

1 ingame screenshot with a white background.

Use a .tga if you dont have The item, there's a tutorial out therr somewhere

1.convert your image to tga MAKE SURE TO NAME IT HEAD

2.go to C:\SteamLibrary\steamapps\common\Toribash\custom(or wherever you installed toribash) and make a new file. you can call it anything, i suggest naming it 0000(so it'll always be at the top of the list)

3. dowload this file and put it in the file you just made(see step 2)

4. Put head.tga (see step 1) in the file you just made (see step 2)

5. open toribash and type /lp 1 [the file you just made(see step 2)] DON'T TYPE /DL [the file you just made] BECAUSE IT WILL ERASE EVERYTHING FROM STEP 1 TO 4.

6. type /opt tori 0 and take a screenshot with a program like gyazo

Ah, nvm.. Yeah, you need to post an in-game image

Im gonna need to do alot of research -.-

Like what?
Just read the Market Rules next time.
