Hello Creators!
We are excited to announce the beta release of Texture Generator, a tool that allows you to create custom textures for your meshes using natural language prompts. With Texture Generator, you can rapidly prototype and experiment with new looks for your experience and accelerate creation.
What is Texture Generator?
Texture Generator creates bespoke 1024 x 1024 textures for MeshParts that you can either import yourself or get from the Creator Store. Texture Generator understands the geometry of your meshes and can intelligently texture it based on your text prompt. For example, if you have a treasure chest mesh, it can differentiate between the wooden exterior and the lock to generate a visually consistent texture.
To enable the beta in Studio, go to File > Beta Features > and enable AI-Powered Texture Generator. Once you restart Studio, you should see a Texture button in the “Model” tab of the ribbon, next to Material Manager.
How to create with Texture Generator
- Import a MeshPart or Model of Meshparts into Studio, or grab one from the Creator Store.
- Open the Texture Generator Plugin from the Model tab in Studio and select the mesh in the Viewport.
- In the tool’s preview pane, pan to set a generation angle that highlights the significant features or surfaces for texturing.
- Enter a prompt describing your desired texture.
- Click “Preview” to create a texture preview.
- Refine your prompts and regenerate previews until you’re satisfied.
- Hit “Save and Apply” to create textures to use in your experiences, for UGC items, and more. Right now, you can generate up to 5 full textures per day.
Texture Generator will work on multiple MeshParts, but will generate a shared texture for all of them. Try texturing each mesh separately or choosing models with fewer meshes to get the best results.
Here are some examples of textures you can generate:
Try it out in this experience!
We’ve created a Texture Generator Demo Place with some sample meshes so you can get started with texturing meshes.
To access this place in Studio, go to the link above, click the 3 dots in the upper right corner, and click “Edit in Studio”.
Once you enter the place, you’ll see meshes that were textured using Texture Generator. You’ll also see blank meshes behind them – try texturing these using Texture Generator.
For example, you can texture the couch with the prompt “blue floral fabric couch” and use it in your experience!
Advanced Options
Texture Generator has a few advanced settings to optimize texture generation:
Generation Angle
Texture Generator lets you set a primary generation angle, so you can specify the most important features of your mesh. This will ensure your selected view is prioritized by the AI model to generate sufficient detail for this view.
You can set the generation angle by rotating mesh in the preview window, or you can manually input XYZ rotation values under Advanced Options.
Setting the generation angle to display the meaningful features of your mesh will result in better generations. Make sure the generation angle displays a view with a high surface area. For humanoid and animal meshes, experiment with different generation angles, such as a head-on view of the face and a side view profile, to find the most consistent and coherent texture.
See our Documentation for best practices on choosing a generation angle.
Specify Front View
When this setting is enabled, the generation angle selected during the preview stage is specified as the “front” of your mesh. This allows the model to better texture meshes with a clear front and back by identifying each side, resulting in more consistent and coherent textures. This is particularly helpful for objects with a clear front and back, like avatars and animals.
Seed Control
Texture Generator also lets you set the “seed," which controls the randomization in AI image generation. By setting the seed before generating a texture, you can ensure you get consistent results each time you use a specific prompt. If you want to vary the look of a generation, try changing the seed or keeping it randomized.
Smart UV Unwrap
What is a UV Map?
In 3D modeling, a UV map is a 2D representation of the surface of a 3D model. Think of it as unwrapping an object’s skin and laying it flat. This map allows 2D textures to be accurately applied to the 3D model. UV coordinates (U and V) refer to the horizontal and vertical axes of this 2D space, similar to X and Y axes in a 2D graph.
What makes a UV map compatible with Texture Generator?
For Texture Generator to create well-formed textures, your mesh’s UV map must fit a few guidelines. Firstly, all UV coordinates must be within the unit square. UV maps outside the unit square will wrap around to the other side of the UV map, creating artifacts and seams in your final texture. Secondly, all UVs must be non-overlapping. Overlapping UVs will result in inconsistent textures and color placements. Lastly, UVs must take up at least 33% of the unit square to ensure the UV space is utilized correctly.
Texture Generator can automatically handle meshes with no UVs or incompatible UVs, so you can focus on bringing your creative vision to life. Smart UV Unwrap, which is enabled by default in the Advanced Options menu, will take a mesh with no UVs or incompatible UVs and generate the UV coordinates necessary for texturing. If your UVs are compatible, they won’t be affected, and you can use your mesh as-is. If you want to guarantee that your UV map will be used, regardless of compatibility, you can deselect Smart UV Unwrap.
Limitations
-
Texture Generator currently only supports texturing of MeshParts, not standard Parts or CSG objects. We plan to expand support to more object types in future releases, so stay tuned for further updates.
-
Texture Generator currently outputs ColorMaps, housed within a SurfaceAppearance. Stay tuned for further updates including Metalness, Roughness, and Normal Map generation!
-
Automatic UV unwrapping will not work on skinned/rigged meshes. You can still apply textures to skinned meshes without auto unwrapping. We aim to address rigged mesh support in the future.
-
Due to capacity constraints in this beta phase, we are limiting the amount of textures each user can generate per day. For now, you’ll be able to generate 5 textures per day. You can preview up to 25 times per day, so we encourage you to iterate and refine your prompts until you get exactly what you’re looking for in the preview before generating a full texture.
Responsibility
While we’re excited for you to get your hands on this feature, we want to remind everyone that you’re responsible for the content you create. Use of Texture Generator is subject to the Supplemental Terms, and like all textures, these creations will go through moderation and must adhere to our Community Standards.
Intellectual Property
Intellectual property (IP) pertaining to generative AI is rapidly evolving. Three best practices for helping protect your IP and avoid infringing on others’ IP are:
-
Ensuring you have the rights for anything you upload to Roblox, regardless of whether you use generative AI.
-
Do not input prompts that use brand names or logos, or attempt to generate creations based on intellectual property where you don’t have the rights.
-
Modifying the output of anything you create or using just assets you own with generative AI can enhance the protectability of what you create.
Generative AI Capabilities
Texture Generator is the latest solution in our generative AI tools to help make creation more accessible. Last year, we launched Material Generator, which can generate repeated, tiling material variants for parts and CSG objects like walls and roads. We’ve also launched tools like Code Assist and Assistant to supercharge your productivity.
What’s Next
Take a look at our Documentation for more tips and best practices, and check out the full video tutorial. Over the next year, we plan to continue improving, including:
- Integrating Texture Generator with Assistant to help make creating with generative AI more seamless
- Adding the ability to refine and edit your generated textures
Thank you for helping us test out this exciting new capability in Studio. Please share your thoughts and suggestions in the comments below. Let us know if you encounter any issues while using the tool. We can’t wait to see all the unique textures you dream up!
