If you mainly make clothing
The workflow that matters is: get the template right, place your art inside the correct panels, and confirm it on a 3D body before paying the upload fee. Meshlox Clothing Studio does the panel mapping from any uploaded image, removes JPG backgrounds, previews on a rotating R6 dummy and exports the flat 585×559 PNG Roblox expects.
If you want 3D UGC, not just shirts
Limited UGC accessories are where Roblox creators earn the most per item, and they need real geometry: a mesh inside Roblox's triangle ceiling, clean UVs, a baked texture and a sane pivot. Meshlox generates that from a prompt or a reference image and sends it into Roblox Studio through the plugin, so you never touch Blender or the FBX import dialog.
Honest take
If your entire output is classic clothing, either tool can get you there — pick the one whose editor you prefer. If you also want 3D accessories, game icons and thumbnails coming out of the same account, with one-click Studio import, that is the gap Meshlox was built for.
