Error upon uploading custom material variant, anyway I can fix?

[zalanka1112 (zablanka)]

Every time I try to upload a custom material variant, it says “Error uploading asset, responseCode 404”

Any way to fix this?

We are very troubled. My friend and I are in the same situation.

BUG - Material Manager - Failed to Upload PBR Textures

This is a current error in Roblox. It can be bypassed by uploading the textures as images in the Asset Manager and then inserting the ID of these images into the URL fields of the Material Manager. A special thanks goes to @Hazelfluff for this solution.
