Just a small update from me this week - This is the Hydro turbine with Cage. Took way longer than I thought it would. I will probably re texture once in the scene - the blue may not work with the landscape. I think the two holes on the side are for mounting in some way - I will probably have to come up with something there although you may not see it once in the water.
