What is XNALara?

So I think this is some posing program or models, can you also animate with it? Set keyframes, etc

Hi and welcome to the XNALara/XPS insider forum.

*What is XNALara

What is this XNALara anyway?
XNALara is a real time posing and rendering program written by
Dusan Pavlicek and had been released for the first time on
February, 20, 2009 on tombraiderforums.com.
Dusan, the creator of XNALara, managed to extract Lara Croft's
model from the game Tomb Raider Underworld (TRU), converted it for his program, using the Microsoft XNA framework, and shared it,
letting people play with it and create art.



Dusan has updating his program many times. Dec 31, 2010 he has stoped the development and has released the program source code [You must be registered and logged in to see this link.] for using without any restrictions [You must be registered and logged in to see this link.] as "Public domain software". [You must be registered and logged in to see this link.]


I've extended the program for the use of non-TRU character with the version 7.2
From that time, XNALara gained a lot of new fans, as it is not
"Tomb Raider" or "Lara Croft" related only anymore, as every single 3d model can
be imported in XNALara via Blender [You must be registered and logged in to see this link.] or 3ds Max [You must be registered and logged in to see this link.]

There is a huge -and quickly growing- list of 3d models and
characters you can use in XNALara and create wonderful renders! Since version 9.7.8 therfore XNALara has the new name XNALara/XPS (Xna Posing Studio)


Abstract:
XNALara - 3D posing software, free of charge, primarily for Tomb Raider: Underworld model. The first model was Lara Croft, wearing her "jungle shorts".


XPS - 3D posing software based on XNALara, for any 3D character. With a rather rudimentary way to make a keyframe animation. Free of charge.
