# How to make game assets with AI: every guide

> Step-by-step guides for game developers: which Summer API models to chain for a 3D character, sound effects, cutscene music, a trailer, voice lines, a logo, textures and more, with the exact CLI, API and MCP steps and what each costs.

Each guide is one real job from a game's production, start to finish: which models to chain and why, the exact request for every step in the CLI, over HTTP and through MCP, and what the whole chain costs at list price. Hand a guide to your coding agent and it can run it for you.

> **[A 3D character](https://docs.summerengine.com/api/guides/3d-character.md)**
>
> Make a rigged, animated 3D game character with AI: a clean concept picture, image-to-3D with a rig and Idle, Walk, Run and Jump on the same job, and a matching portrait for your dialogue UI. Exact CLI, API and MCP steps and what it costs. The whole chain: \$1.817.

> **[Sound effects](https://docs.summerengine.com/api/guides/sound-effects.md)**
>
> Make a complete game sound effects pack with AI: UI clicks, footsteps on four materials, hits, swings, pickups and a looping ambience, as one batch. Prompts that work, lengths, loops, file names, mixing and keeping the set consistent, with exact CLI, API and MCP steps and the cost. The whole chain: \$0.184.

> **[Cutscene music](https://docs.summerengine.com/api/guides/cutscene-music.md)**
>
> Make game music with AI that sounds like one score: a cutscene cue timed to the scene's length, a menu loop and a combat theme that share one musical identity, plus a victory sting. Tempo and bar math, prompts that work, loop points and mixing, with exact CLI, API and MCP steps and the cost. The whole chain: \$0.58.

> **[Cutscenes](https://docs.summerengine.com/api/guides/cutscenes.md)**
>
> Make a game cutscene with AI that keeps your character on-model: a character reference picture, a style frame, image-to-video shots, sound made from each finished shot, a voice line, a music cue and sound accents, then assemble the shots. Exact CLI, API and MCP steps and what it costs. The whole chain: \$2.721.

> **[A game trailer](https://docs.summerengine.com/api/guides/trailer.md)**
>
> Make a game trailer with AI around your real gameplay: key art, an image-to-video hook shot, transitions, title cards, a trailer music cue, a voiceover and hits, then a 16:9 store cut and a 9:16 social cut. Structure, capture tips, exact CLI, API and MCP steps and the cost. The whole chain: \$5.253.

> **[Voice lines](https://docs.summerengine.com/api/guides/voice-lines.md)**
>
> Make voice lines for game characters with AI: cast each character from the model's voice list, direct delivery with punctuation and stage words, make story lines, multi-character conversations and hundreds of combat barks, and voice other languages with the same cast. Exact CLI, API and MCP steps and the cost. The whole chain: \$0.068.

> **[A logo and vector art](https://docs.summerengine.com/api/guides/logo-and-vector-art.md)**
>
> Make a game title logo with the exact lettering you typed, on a transparent background, plus an emblem, a one-colour version and flat vector-style illustrations in the same style. Which models get text right, exact CLI, API and MCP steps, what to check before you print or ship, and what it costs. The whole chain: \$0.785.

> **[Seamless textures](https://docs.summerengine.com/api/guides/textures.md)**
>
> Make tileable ground, wall and material textures for your game with AI: one anchor texture, a matching set from it, a seam check you can trust, a free normal map, and tiling in the engine. Exact CLI, API and MCP steps and what it costs. The whole chain: \$0.24.

> **[Props and an environment kit](https://docs.summerengine.com/api/guides/props-and-environment.md)**
>
> Make a style-locked 3D environment kit with AI: one style sentence, a concept sheet, a clean picture per piece, image-to-3D with a polygon budget, batches of 20 to 100 pieces, and scale and placement in the engine. Exact CLI, API and MCP steps and what it costs. The whole chain: \$14.621.

> **[Icons and item sprites](https://docs.summerengine.com/api/guides/icons-and-sprites.md)**
>
> Make a matching set of inventory icons and item sprites with AI: one style anchor, the same style words and seed, a reference picture for every icon, transparent backgrounds, the right sizes, pixel art, and simple sprite animation. Exact CLI, API and MCP steps and what it costs. The whole chain: \$1.764.

> **[An animated title screen](https://docs.summerengine.com/api/guides/menu-background.md)**
>
> Make an animated title screen with AI: key art with room for the logo and menu, a short video loop with no visible seam, a menu music loop that repeats without a gap, a confirm sound, and the scene that plays it all. Exact CLI, API and MCP steps and what it costs. The whole chain: \$1.216.
