If you are looking for an easy way to make mesh things, this is for you. Yuzuru Jewell makes a collection of tools for making things you can upload to Second Life™. A new version of Tatara is out. Inara has done a quick review of it. See: Tatara: a furnace for creating sculpts and mesh.
The collection consists of: TATARA and ROKURO Pro SOMATO, SHIBORI, NOMI, and KUMIKI Serial Box Shop. You can find them here: KANAE PROJECT. I don’t know if Yuzuru’s tools were used to make the tank. I just thought it too nice not to show.
There are versions for Windows, Mac, and Linux. Some versions come in both 32 & 64-bit.
You can get a free 3 day trial of the software from the web site. If you like it, you purchase a license in-world at: Phasic Foo. Tatara licenses cost L$500 (US$1.95). I recommend you visit the store whether you decide to buy Tatara or not. There is some neat stuff there. I wasted a bunch of time there, but it was great fun.
Tarara is easier to learn than Blender. It is not as powerful as Blender, but it is easier to learn. The $2 price shouldn’t stop anyone and it is easier to learn. Oh… check Inara’s review and if you’re interested see the tutorials at: Yururu’s Tatara blog. And… did I mention it is easier to learn than Blender?
