Generally you can right-click the item on the list (the one in the bottom reight corner) and select save or export. 

i've a question too... today i tried to export a model as usual from vue 8.5 (it's my dropship, you can find the model and all the maps in the 3d models section), but it seems i can't do it as a sigle file without loosing the textures. (i've uploaded other items before, and there was no prob...) 

anyone know's what am i doing wrong???

thanks
