Sorry to triple post, but I finally completed a model of an Industrial Fan. I can't take full credit for this, as I followed a highly detailed tutorial and the textures were provided by said tutorial, but still thought I'd post here for people to use. It is kinda high poly, but I think it turned out pretty nice. Added it to the main page, also here is a screen. Uploading to ModDB right now. Will post the link when it gets authorized.
Also made an animation of the fan blades slowly spinning, but still trying to figure out how to add that into the Amnesia editors. Will upload if I can figure it out.
