The actual workflow for Roblox Making Shirts
You download the shirt template from Roblox, open it in an image editor, paint your design onto the correct areas, and upload it back. The catch is that the template has a very specific resolution and layout that Roblox expects. Most people mess this up on their first try because they use the wrong canvas size or don't realize which pixels map to which body part. I spent about three hours once fighting with a shirt that looked perfect in my editor but came out completely garbled on avatars. Turned out I had opened the template in GIMP without checking the pixel dimensions first, and GIMP had resampled it down to something close but not exact. The arms were stretched weirdly and the torso pattern was offset by a few pixels. The workaround was simple: always verify the canvas is exactly 512 by 512 pixels before you start painting, and never let your editor auto-resize the image when you import the template.
How Roblox Making Shirts actually works technically
When you create a shirt on Roblox, you are uploading a PNG image that gets UV-mapped onto the 3D avatar mesh. The shirt template is a flat 2D representation of how that mesh unfolds. The left half of the template contains the left sleeve, left torso, and left leg. The right half contains the corresponding right-side body parts. The top strip is the head area, and the bottom section handles the feet. This layout is not intuitive at all, and Roblox does not make it obvious that the template flips horizontally on the right side. The file you upload needs to be a PNG with transparency if you want see-through areas. JPEG does not support alpha channels, so patterns will render as solid blocks where you expect them to be invisible. I used to convert my designs to JPEG by accident and waste an hour wondering why the shirt looked opaque instead of matching my reference mockup. There is also a size limit. Roblox caps shirt textures at a maximum file size, and I have seen people get their uploads rejected because their PNG was uncompressed and ran over the limit. Compressing the image before uploading usually fixes this without visible quality loss, since the textures are small enough that aggressive compression is barely noticeable on actual avatars.
Common mistakes I see people make
The biggest issue is symmetry. People design one side and mirror it to the other, but the template already accounts for mirroring. If you mirror your design again, you end up with double patterns on one side and nothing on the other. I learned this the hard way when a client sent me a shirt design that looked fantastic in Photoshop but rendered completely broken on every avatar in the game. The fix was to check the template orientation first and only mirror if the template itself is asymmetric, which most built-in templates are not. Another pitfall is color profile. RGB versus CMYK conflicts can shift your colors slightly when the image gets uploaded to Roblox's servers. This is usually a minor shift, but it becomes obvious when you are working with brand colors that need to match exactly. I recommend keeping everything in sRGB and checking the final result on an actual avatar before publishing, since the Roblox preview can sometimes look different from your editor. People also forget that the shirt template includes pre-drawn outlines for seams and joints. If you paint over these lines, the avatar will still render the underlying mesh lines on top of your design, which can look like unwanted artifacts. Some designers embrace this and use it as part of their aesthetic, but it is something to be aware of when you want a clean, seamless pattern.

When shirt making is not the right tool
Roblox shirts work well for simple patterns, logos, and solid color blocks. They break down when you need complex gradients, photorealistic textures, or designs that span across multiple body parts with precise alignment. For those cases, you are better off using a full-body decal or commissioning someone who understands the UV mapping quirks. The platform also does not support advanced texture features like normal maps or roughness maps on shirts. If you need lighting effects or surface detail that responds to in-game lighting, shirt textures alone will not achieve that. I have seen designers try to fake normal mapping by painting shading gradients into their shirt designs, but the result looks flat under Roblox's lighting engine and usually gets called out in feedback. There is also the issue of visibility at small scales. Shirt textures are rendered at a fixed resolution regardless of avatar distance, which means fine details can become invisible when viewed from far away. This is a fundamental limitation of how Roblox handles player cosmetics, and the only real workaround is to design with bold, high-contrast elements that remain readable at typical viewing distances in your game.
A practical workflow that saves time
I keep a master copy of the shirt template in my project folder and always work from that exact file. I use Krita for painting because it handles transparency well and does not auto-resize images by default. I check the design on an actual Roblox avatar using the in-game preview before publishing, since the editor preview can sometimes look different from the live build. This process usually takes about twenty minutes once you have the template and tools set up, compared to the hour or more I used to waste on trial-and-error uploads. The Roblox Making Shirts process is straightforward if you understand the template layout and respect the technical constraints. It is frustrating if you ignore the pixel dimensions or assume the right side of the template behaves the same as the left. The first time you get your upload right, it feels like you have figured out a system that most people overcomplicate unnecessarily.
