A world that holds its palette

A cover is a promise about a place. Neta Studio keeps the cast, the buildings and the palette together in one world, so the second cover still looks like the same game. You write the beat — who stands where, what is under the ground — and GPT Image 2 draws it inside those rules. Every frame lands as a work you can open, re-run or publish.

The cast is already on file — Characters exist as atoms with covers, so a named hero arrives with a face, an outfit and a colour set before you type anything.
One model for the cover — GPT Image 2 for the frame you ship, a faster model for thumbnails and colour tests; the prompt stays the same.
Every cover is a work — Drafts stay in the world, so you can put the port at dusk next to the port at dawn and publish the one you kept.

Questions, answered.

What makes a pixel cover read as a sandbox RPG?

Two layers, in one frame. A town or camp on the surface, then a clean cross-section at the bottom edge showing the cave, mine or corridor underneath. That cut is what tells a player the world goes down as well as sideways.

Is this a sprite generator?

No. It makes one wide cover — box art you can put a title on. Sprites, walk cycles and sprite sheets are a different job with different constraints, and this page is not the tool for them.

Why is the top third of the frame empty?

Because a cover needs somewhere for the name. The prompt reserves a quiet sky band; add the title in any editor afterwards, and keep the lettering out of the model so it does not invent half-readable text.

Can I keep the same world across several covers?

Yes, if you keep the palette and the cast the same. Name the character, reuse their existing cover as the reference, keep the same building shapes and repeat the same palette line. In a Studio world both are stored, which is why the nine frames here still look like one shelf.

What size should I ask for?

1536×960 for a 16:10 cover, or 1536×864 for 16:9. Downscale with nearest-neighbour, never a smooth resize — a bilinear shrink turns hard pixel steps into mush.

Will it add a title or a logo by itself?

Not if you say no, and you should. Models draw convincing fake lettering that reads as garbage at full size. Keep text out of the image and set it in an editor where you control the font.

Can I make a cover with no character in it?

Yes. Drop the named character and keep the layers: a town, a road, a cave mouth. Many storefront covers are places only. The character is there to give scale, not to fill the frame.

Can I use it as a store capsule or a banner?

A 16:10 frame crops cleanly to Steam's 616×353 capsule and most store banners. Keep the title band clear and the character away from the centre, since storefront overlays sit there.

Draw the world before it exists.

One line gets you the box art: town above, cave below, title space at the top — then keep the palette for the next island.
