How about Pixie?
For me there was a very big bug!
Nothing can be loaded or saved! 
Solution were minimize the path and put objet, save object or save image
in the folder :⊠\Program Files\Kerkythea Rendering System\models\myobject.obj 
Bug is Windows or kerkythea? :I am not enough qualified for judge

Well, other programs donât have that problem and they run just fine on Windows. 
Curiously the problem seems exist only for a little number of person

My little test animation (1.2 meg avi) some jerked because you can move the mouse during the animation 
Mega cool image manipulation prog.
Comes out of the Astronomy corner of the imaging business, but that does not mean that we canât use the HDRI capabilities and the very cool image correction/manipulation offerings:

@lemon : yes Astronomy was always pioneer in computer language (forth) or image treatment !
And generally also men are encyclopaedist like this one (english/french)

Ps My favorit site is
Astronomy Picture of the day 
Canât make it workâŠ
Certainly because of OBJ import failuresâŠ

My little try (here just a simple collage of the initial object)
I have taken a simple cube (only triangles ! ), import in âIvyâ
Double click elsewhere one time on the cube ,
click on âgrowâ
when satisfy click on âgrowâ for stop the process,
and click on âbirthâ for create the object - export it
et voilĂ
Some precisions
Left Button = Move
Right Button = Zoom
Shift + Left = Rotate
And you must click (or not) for flip ânormalâ for see the âlittle green square start rootâ when you âdouble clickâ the button âGrowâ
Import object must be âdark greyâ
Click again âGrowâ for start the process
Click again âGrowâ for stop the process (seems you canât have 2 roots in the same time)
Click âBirthâ for create the object
Click âsaveâ for save it
As a leaf = 2 triangles, a brunch segment= 6 triangles itâs normal that you obtain big file
Here (following image) 800 000 facets
35 second create
100 mega (yes) but today machine have 2 gigas memories (Zbrush manage easily 10 000 000 polys)
Render in Anim8Or 25 second (800 * 600 with scanline)
Seems not very long for a an old machine of 3 years old
But tell me if you can load âalphaâ in the Ivy prog?
me I canât, I must put âAlphaâ outside on the resulting object (in Anim8Or for example)
AAAAAHHHHH ! I have the explanation ! Graphic video card must be not too old for see textures in IVY
