System: Checked if it is already online on Sketchfab?
Me: Yes. I just used a different browser. Typed my user name on the site's search box and "Voila".
System: Copied and pasted your user name?
Me: Sure. Wrong again!
System: Typed using lower case letters only?
Me: Hum hum. Wrong once more!
System: Checked if there are no spaces before your user name?
Me: Yup. No spaces there. And, guess what. (^_^;)
System: How about spaces between words in your user name?
Me: Ding! Ding! Ding! WE HAVE A WINNER!
Roadmap to success:
- case sensitive;
- no spaces at all;
- it's online;
*Note that you may come across a problem that I did not. Therefore, this is a solution, not a definitive one.
Thanks for the writeup liandur001 ! For reference, can you link me to your sketchfab user page so I can test it out and see if we can make it easier?
