How I Make Roblox Game Thumbnails in 4 Seconds Instead of 4 Days

#ai #gamedev #roblox #design

If you ship anything on Roblox, you already know the quiet bottleneck. The gameplay can be solid, but on the discover page you get about half a second to win a click, and that half second is almost entirely the thumbnail and the icon. Good art is the front door.

The problem is that good art used to be slow and expensive. A freelance GFX thumbnail runs anywhere from 50 to 500 dollars and sits in a queue for days. Multiply that across every update and every event and you can see why most small creators end up recycling tired art.

I switched to generating mine with Artly, an AI image tool built specifically for Roblox assets. Here is the actual workflow, the prompt tips that matter, and the honest tradeoffs.

What Artly is

Artly is a text to image service focused on Roblox. You describe what you want in plain language and it returns thumbnails, game icons, textures, UI assets, or GFX renders. No Photoshop, no Blender, no code. It runs two models: a primary model called Orion 1 that the company says was trained on Roblox art styles, and a lighter model called Artly Mini on the free tier.

The 4 second workflow

This is the loop I run now.

  1. Open Artly and pick the mode you need (thumbnail, icon, texture, or UI).
  2. Describe the scene in plain English. Mood, lighting, character pose, background, focal point.
  3. Generate. It takes a few seconds.
  4. Iterate. Tweak the prompt and regenerate. I usually land it in three tries.
  5. Export. On a paid plan you get HD output and a commercial license, so it goes straight into your game.

Prompts that actually work

The difference between generic output and a clean result is detail. Compare these two:


Bad:  a cool thumbnail for my game

Good: a heroic Roblox character mid jump over a glowing neon city,

dramatic rim lighting, bold close up composition,

vibrant blue and orange color scheme
Enter fullscreen mode Exit fullscreen mode

Name the lighting. Name the camera angle. Name the colors. Since the model is trained on Roblox styles, you mostly just need to point it in the right direction.

What it costs

There is a real free tier with 3 generations per month on the Mini model. The Creator plan is about 12 US dollars per month and includes 110 generations, the Orion 1 model, HD resolution, prompt help, and a commercial license. There is a Studio plan around 25 US dollars per month for teams. You can pay in US dollars or Robux, and there is a Roblox Studio plugin and a Discord bot.

Honest caveats

  • Prompting is a skill. Your first few tries might be rough, and that is normal.
  • AI art is a real debate. Some of the Roblox community dislikes AI thumbnails, and copyright rules for AI images vary by country. Artly says it uses commercially licensed models and frames the tool as a creative partner rather than a replacement for artists. Where you land on that is your call.
  • A fast thumbnail will not save a boring game. The art opens the door. The experience has to keep people inside.

Try it on one update

Do not overthink it. Next time you push an update, generate the thumbnail instead of recycling the old one, and watch whether your click rate moves. That single test is what won me over.
