'ASCII FBX Texture from Reality-capture have 4 party but can't really Convert to Image?

Just like the title, We have some ASCII FBX (with embedded Texture) created by Reality-Capture, but when we open the FBX with VSCode, we can see after content, there are actually 4 part, just like the image, and only the first part can convert (use Base64 to Image) to Texture, and it's not a fully Image, just a quarter of the image, but put the other 3 part after first part, it will never going to convert successful, it's also can't works if we put the rest 3 part one by one.

Is anyone met this problem? How should I convert those 4 part as a full texture, quiet curious if its special for Reality-Capture?
