floccipocci: There are instances of missing models. Mainly the doors and weapon models.

1) During the tutorial, all the door models are missing. You can see into the next room, however there is an invisible barrier in the way. I thought that it was normal, until I played the tutorial where you have to unlock doors then I realize that the doors are missing.

2) Also during the tutorial, the weapon models are missing, all I see are empty hands holding invisible weapons that fire. :/

The weapon models are visible during the final tutorial mission however.

But the door is still missing, in the first mission.

floccipocci: Thanks for the reply!

I've not tried disabling instancing yet.

However I found out that changing to DirectX mode works. The doors are now visible.
To confirm it, I unselected DirectX mode and the doors are missing.

Will try the instancing option.
