FAQ
What is the difference between a Roblox GFX maker and a thumbnail maker?
GFX puts the avatar, pose and character scene first. A thumbnail workflow then adapts that scene for a specific discovery slot, readable hook and title treatment.
Can I make GFX for a Roblox game cover?
Yes. Describe the game genre, avatar pose, camera angle and background, then keep important title copy in an editable layer instead of baking it into the pixels.
What size does the Roblox GFX maker export?
The focused promotional workflow exports a 1920×1080 PNG, which gives you a clean 16:9 master for thumbnails and social crops.
Can I keep my avatar and game style consistent?
Attach a representative screenshot or style reference, and repeat the same avatar description, palette and lighting rules across the set.
