Hi, in terms of bulk uploading I would for example use some form of scripting (outside of roblox) like a JSON or Python script which would allow the code to go into your files to a specific area where all the image files would be and then re-upload them using the Image uploader on Roblox.
Not sure as to whether there is a better alternative or any Roblox cap limit on Decals per day.
Also I think Roblox is having some issues with Images at the moment since when I uploaded mine, it came out like this:
I would be patient for a couple of days to see whether it’s just a Roblox side issue or whether you may need to of course redo it all. In which case I wish you the best of luck.
I’ve also had problems with decals, but I did not get a message saying it was corrupted.
Somehow, there was another decal ID that was the untouched decal(for me). I got this by putting the ID in an ImageLabel in Studio, and somehow the link changed to the ID with the good file. Edit 2: Here is the fine version. It does not show up in my inventory or through the my decals tab.
Here is what I got for the bad one.
It even shows up differently on the tab with the decals I created. I wanted a White circle with black border with a black A inside it, but one version turned some stuff green.
EDIT: I also forgot to mention that for one of the decals the Font of the A was altered.
This corruption only happened with the white decals, but I’ve had to use the second ID for the decals I was using.
Not sure if this will fix it, but that’s how I got over this problem.
