I love blender and thought it was great ever since I started using it (about version 2.1). Sure, I stared at it dumbfounded the first few times I saw it, but once I started locating a few basic areas (spacebar to add stuff, object info area, material info area) it really started to make sense. If you know the hotkeys and how to navigate it’s really hard to see any reason to want it any other way. You may wish to print out a list of your most necessary hotkeys for at least the first few sessions though (I never actually did but thought it would’ve been a good idea). Interface is very smooth and highly customizable as well.
Also, don’t forget blender has video tutorials which can be very helpful for some basic operations. Nothing is as effective as someone showing you exactly what to do as they explain it.
If I ever do anything with java in 3D, I’m going to be using Blender. I probably won’t bother learning anything unless I can export models with Blender. There’s just sooo much stuff you can do with it. Make sure you check out the metaballs and the fluid engine. While not especially useful for modeling, they are rather cool and you can always duplicate out parts if you manage to obtain a shape you need. Btw, I just figured out (literally 5-minutes ago) if you make a meta-object, select it and press “alt-c” to convert it to a mesh. Also, if you have too many faces, just switch to Object mode (tab), go to the Editing context (F9) and click Add Modifier - Decimate. You can turn down the number of faces based on a percentage, and Blender will try to remove the faces with the least damaging effect (you might have to manually go in for some of the details but it can still be quite useful).
Good luck.
