Mint is an AI agent that helps you create, refine, and share Worlds, 3D Models, Materials, Asset Packs, and Audio. This page covers common questions about working with Mint and its supported surfaces. ## FAQ ### What is the difference between a World and a 3D Model? * A **World** is a place you can walk through. * A **3D Model** is a single object or character you can open, download, and convert into supported file formats. ### What is an Asset Pack? An **Asset Pack** is a cohesive set of related 3D Models. Use one when you need a set, kit, lineup, roster, clothing line, or prop collection in one shared style. ### What is a Material? A **Material** is a standalone PBR texture asset. Use one when you need a seamless surface or texture-map set, such as concrete, stone, bark, metal, fabric, tile, or leather. Materials include generated maps such as base color, normal, roughness, metalness, and height. They are not 3D Models and do not include mesh geometry. ### What is Audio? An **Audio** asset is a generated playable sound file. Use one when you need sound effects, UI sounds, short ambience, background music, intro music, lore cues, theme music, loops, or ambience beds for a game, app, World, or scene. Audio starts from a text prompt. Mint decides whether your request is a sound effect, short ambience, music, or another general audio request. ### Do I need to sign in to use Mint? No for browsing. Yes for creating, saving Favorites, and managing billing. ### What is a Preview? A Preview is the image Mint shows before final generation. You can review it, edit it, or cancel before you continue. ### Where do my creations go? * Worlds go to your **Profile** under **Worlds**. * 3D Models go to your **Profile** under **3D Models**. * Materials go to your **Profile** under **Materials**. * Audio assets go to your **Profile** under **Audio**. * Asset Packs with generated items can appear under **Asset Pack**. Their finished items also appear as 3D Models. * Failed or cancelled items with a usable Preview go to **Previews**. ### How do I edit an existing World? Open the World and click **Reuse Prompt** or **Edit World**, if shown. Mint sends you back to Chat with the World as the starting point. ### Can I make something private? * Worlds can be hidden from your public profile with **Hide from profile**. * 3D Models can be switched between **Public** and **Private**. * Materials can be switched between public and private when the visibility action is available. ### Can I download my 3D Model, Material, Asset Pack, or Audio? Yes. Open a finished 3D Model and use **Download GLB**. For final Asset Pack outputs with downloadable GLBs, use **Download ZIP** to download the pack as a ZIP. You can still download an individual child model from the focused item. Open a finished Material and use **Download** to download the generated PBR map set as one ZIP. Open a finished Audio asset and use **Download** when a downloadable audio file is available. Finished 3D Models can also be converted into `GLB`, `OBJ`, `STL`, `USDZ`, and `FBX` when conversion is available. In Chat, ask Mint to convert the finished model and name the formats you need. `OBJ` and `FBX` downloads can be ZIP packages so Mint can include the model file, material sidecars, and texture images together. ### Can I view my 3D Model in AR? Yes. AR is a viewing capability for finished 3D Models. Generate a 3D Model as usual, then open Mint on a mobile browser, open the finished model from your **Profile** or the asset panel, and tap **AR**. Finished Asset Pack items are 3D Models too, so you can open an individual generated item on mobile and tap **AR** when available. ### Can I optimize a generated 3D Model? Yes. Open the chat with a finished generated 3D Model and ask Mint to optimize it. Optimization prepares a smaller GLB for delivery, download, or import. It is not a visual edit, and Mint keeps the original GLB available. Each model optimization costs 20 Credits. For Asset Packs, each generated item you optimize is charged separately. ### Can I retopologize a generated 3D Model? Yes. Open the chat with a finished generated 3D Model or Asset Pack and ask Mint to retopologize it, apply smart topology, or make a quad mesh. For Asset Packs, you can retopologize one generated item, selected generated items, or all generated models in the pack. Mint creates new derivative models with quadrilateral topology and keeps the original models unchanged. The retopologized models preserve the source models' look and thumbnail when possible. Each smart topology operation costs 394 Credits per model. It uses the original finished generated model as its source. For Asset Packs, each generated item retopologized is charged separately. ### Can I upload reference audio or clone a voice? Not in the current Chat flow. Audio generation is text-to-audio. Mint does not currently support uploaded reference audio, audio-to-audio editing, voice cloning, or a dedicated lyrics workflow for this capability. ## Troubleshooting ### I cannot start creating Check these first: * You are signed in. * You have enough Credits or an available optional plan quota. * Chat is not showing a billing, quota, or active-generation blocker above the composer. If Mint says too many generations are already running, wait for one to finish before starting another. ### My upload failed Check these basics: * The file type is supported by the picker. * The image is under the on-screen size limit. * The composer is not already at the on-screen image limit. * Use a normal image file or a direct image URL when possible. ### My Street View or listing link did not work Try again with: * A fresh Google Maps or Street View link * A supported `Zillow`, `Airbnb`, or `Redfin` page * Fewer redirects or copied tracking text around the URL If it still fails, upload images manually instead. ### My Preview failed or I cancelled it Open your **Profile** and go to **Previews**. From there you can: * Click **Continue** to return to Chat * Click **Delete** to remove the failed item ### My World is missing from my public profile If it still exists but is not public on your profile: 1. Open the World. 2. Open **World Options**. 3. Check whether it was hidden from your profile. ### My model is missing from my public profile Open the gear icon on the model card and check **Model Info**. It may be set to **Private**. ## Known limits ### Creation limits Mint shows current image, billing, quota, and active-generation limits in Chat or the capture flow before you submit. Use the message Mint shows as the source of truth. ### Rollout-dependent features These may appear only for some users: * **Subscribe & Save** * Other checkout options * Globe-style explore mode * Credit treasure hunts inside Worlds * Redemption codes * Referral Credits * Native App Store or Google Play billing ### Free previews Eligible users may receive a limited number of free previews. Because this can vary by rollout or product copy, always rely on the current in-product message. ### Studio * **Studio** is restricted. * Some Studio controls can be visible before they are fully usable, such as **Export**. ## Good recovery habits 1. Check your **Profile** before restarting work from scratch. 2. Use **Previews** to continue failed or cancelled items. 3. Keep your prompts clear and specific. 4. Buy Credits or review your optional plan before launching several generations at once. 5. When in doubt, test with a simpler prompt first. ## Need more help? * Recheck the relevant guide page: [Getting started](/getting-started), [Create worlds and 3D models](/create-worlds-and-3d-models), [Create with Chat](/create-with-chat), [Capture with the Mint mobile app](/mobile-capture), [Explore and share](/explore-and-share), [Account and profile](/account-profile-and-billing), or [Plans, Credits, and billing](/plans-credits-and-billing). * Contact [Mint support](/support) if you still need help.
