To create your own shirt on Roblox, start by designing it using image editing software like Paint.net, Gimp, or Adobe Photoshop. Download the Roblox shirt template, which includes sections for the torso and arms, each divided into front, left, right, up, down, and back. Ensure your design fits within the maximum limits for gloves and lower leg details on R15 models.
Open the template in your chosen software and create a new transparent layer to start designing your shirt. Use the template as a guide to ensure your design matches the avatar correctly. Add textures, colors, and details using various tools, and organize your design with layers for easy adjustments.
Once your design is complete, save it as a PNG file. Go to the Roblox “Create” page, select “Shirts” from the asset type menu, and click the “Upload” button. Choose your PNG file, enter a name and description for your shirt, and click “Upload” to publish it to the Marketplace.
Before finalizing, test your shirt on a dummy avatar in Roblox Studio. Make sure the shirt looks as intended and make any necessary adjustments. By following these steps, you can create and upload your own custom shirt on Roblox.
