Roblox Limitations

Roblox has several limitations within the platform. The following is a list of the current critical limitations. This list will be reviewed and updated periodically as the platform grows.

Please note that although this list attempts to capture the main limitations within Roblox, it is not an exhaustive list. In addition to the list provided, Ideators should conduct their own due diligence before submitting ideas to the Slingshot app.

  • Performance: Roblox games can experience performance issues if they contain too many parts, scripts, and other assets. This can cause lag and make the game unplayable for some players.

  • Physics engine: Roblox uses a physics engine that has some limitations, such as not being able to handle certain types of collisions or interactions between objects.

  • Limited scripting capabilities: While Roblox Studio allows users to write scripts in Lua, there are some limitations to what they can do. For example, users cannot create their own custom functions, and certain programming structures are not supported.

  • Limited customization options: While Roblox Studio provides many assets and tools for creating games, there are limitations to how much users can customize certain aspects of their games. For example, users cannot create their own custom meshes or modify certain game mechanics.

  • Platform-specific limitations: Roblox games are limited by the capabilities of the platform they are running on. This means that games may have different limitations depending on whether they are being played on a desktop computer, a mobile device, or a console.

  • Limited monetization options: While users can make money from their Roblox games through game passes, developer products, and other means, there are limitations to how much money they can earn and how they can monetize their games.

  • Content moderation: Roblox has strict rules and regulations for user-generated content to ensure that it is appropriate for all ages. This can limit the types of content that users can create and share in their games.

  • Polygons limit: Roblox limits the number of polygons that can be used in 3D models to improve game performance. The limit is around 5,000 polygons per model.

  • Texture size limit: The maximum texture size for an asset in Roblox is 1024x1024 pixels. Larger textures will be automatically downscaled by the engine.

  • Asset file size limit: The maximum file size for an asset in Roblox is 100 MB. This includes textures, meshes, and other assets.

  • Limited import formats: Roblox Studio only supports a limited number of file formats for importing 3D models, such as FBX, OBJ, and 3DS.

  • Animation constraints: Animations for Roblox require a specific set of constraints to be followed, such as having a certain number of keyframes and using specific bone structures. These constraints can make it challenging to create complex animations.

  • Limited vertex colors: Vertex colors are limited to 1 color per vertex, while some other 3D engines allow up to 4. This can make it challenging to create complex textures or color patterns.

  • No dynamic lighting: Roblox does not support dynamic lighting, which means that all lighting in a scene must be baked into the textures. This can limit the visual quality of a scene and make it difficult to create realistic lighting effects.

  • Limited physics interactions: Physics in Roblox are limited and not as accurate as in other game engines. This can make it challenging to create realistic physics interactions between objects.
