After creating a facial accessory and going through the asset configuration in Roblox Studio the accessory showed the texture in the preview box. However when I paid for the review and uploading the asset to the Marketplace the texture doesn’t show in the 2D preview.
This seems to be a common issue lately-sometimes the 2D preview on the Marketplace doesn’t show the texture, even though it works fine in 3D and in-game. Usually, this is just a display bug on Roblox’s end and not something wrong with your asset. If your item looks correct when using “Try on” or in-game, you should be good.
You can try clearing your browser cache or checking the page from another browser, but most of the time, it just takes a bit for Roblox to update the preview. If the problem sticks around for a while, you can follow up with Roblox support or keep an eye on this thread for updates from staff.
