I recently stumbled across this model that I began back in 2007, but left unfinished.  The L1 (its Imperial German Navy designation, it is also known as LZ 14) first flew in 1912 and was lost in a thunderstorm the following year.

Cool

Toon renders of the fore and aft gondolas:

A Maybach engine.  One in the forward gondola powers to propellers; two in the aft power a prop each.

Looks good

The basic mesh is finished, although based on past experience I suspect some refinements will be needed.  At the moment I'm optimizing the materials.  Here are the latest renders of the fore and aft gondolas.

I like it

This is awesome!

Now in Poser and partially rigged.  Still needs texturing and some props.  There will be machine guns for the top platform and gondolas and possibly cabin seats for an imagined commercial transport version.  Here are a couple of Poser toon renders.

Nice

Beginning materials.

Texturing is about done.  I'm still working some props.  Here a couple of renders.  The aft gondola with its two engines.

The cabin with its simple gun emplacements.

There won't be any additional furnishings, but there's room lots of stuff from your collections.

The imagined passenger version is furnished, inspired by a photo of another Zeppelin.

Looking real good

Testing in DAZ Studio.  Looks good.  Here are a couple of DS IRay renders

Very nice looking

These are great! 

Now packaging up.  Here are a couple of promotional renders inspired by some historical photos:

Looking forward to it

In the release queue.
