hello, i got a little problem, when i try to install on my steam it's doesn't work, any idea ?

@lerotyny: The issue is probably because the model is high poly. To fix this in-game, go to Settings -> Content -> Workshop Settings. Then set the Workshop Polygon Limits to OFF. After that, click on the button to clear your workshop cache so that it essentially resets your workshop subscriptions. Then close and re-open the game. Afterwards the model SHOULD appear.

If it still doesn't appear after that let me know and I'll see if other people are having a similar issue.
