I used Trnia for this assignment and I didn't really like it. Even it's only $0.99, it still doesn't worth the money. First of all, the preview took forever and I had to exit the app way too many times to manually refresh and finally finish previewing. And that applies to publish the project too. After the whole thing's done. I linked my sketchfab account to Trnia and went back to my profile page. Somehow it's not showing up in my project. It's just gone. (I still can't find it in my profile). I have 0 project and there's nothing in my Queue or my Activity. I managed to find it by search my username in the app and found my model.

I wanted to modify my model in Maya to delete the extra faces. I downloaded my model from Sketchfab and imported it to maya only to find the whole model are made up of triangle faces which doesn't really work in maya. For future use I definitely wouldn't use this app. I think it's easier to just box model in Maya.
