Turning Trees into rocks

[TaylorTuna]

I'd like to have my units harvest rocks instead of trees

changed the model to rock chunks and they show up fine in the editor, but dont show up at all ingame

i've tried just about everything i can think of, any help would be nice

Set the field "Art - Model File - Has Lightweight model" = False.
