CC0 first (anything goes, including earning money; credit is welcome). CC BY only with the author credited. Never NC (non-commercial), ND (no changes) or “personal use”: games on klyo earn from ads. ## How do I credit third-party assets in my game? One line per asset in LICENCJE.txt inside the package. The klyo sieve reads it on upload: a credited asset passes without questions, an uncredited author found in model or sound metadata is a gate warning. Example lines: `Playing Cards Pack, autor: Kenney, https://kenney.nl/assets/playing-cards-pack, CC0 1.0` `Universal Base Characters, autor: Quaternius, https://quaternius.com/packs/universalbasecharacters.html, CC0 1.0` `weathered_planks, autor: Poly Haven, https://polyhaven.com/a/weathered_planks, CC0 1.0` ## How do I keep a 3D game fast on a phone? A beautiful game that takes half a minute to load loses players before they see it. Five rules: - .glb models (one file with textures), not .fbx or .blend - 1k or 2k textures as JPG or WebP; 4k only where the camera gets close - one atlas instead of hundreds of small images - short OGG or MP3 sounds, seamless music loops - first download on a phone up to 20 MB: stream the rest during play ## What should I never put in my game? - Assets marked NC, “non-commercial” or “personal use only”: a game on klyo earns from ads. - Models from Sketchfab and similar sites without checking each model's license: many are CC BY-NC. - Characters, logos and music from other brands (Mario, Pokémon, films, radio songs), even if some site offers them “for free”. - Stock photos as game art: the license usually does not cover games. ## Can an AI assistant download game assets on its own? Yes, if it works with klyo over MCP. The first tool it calls hands it the same list as this page, with download addresses and the credit format. Before it writes the gameplay, it proposes a version with real models and sounds. It downloads sources with an API or a direct file itself; for the rest it gives you the address and tells you where to put the files.
