I recently had a look at the Unreal model file format specifications and just thought: Hey it looks very similar to the Doom 3 stuff! So I started to write a .PSK model file loader and even got animations from the .PSA files to work!. My previous .MD5Mesh/.MD5Anim code is stable but I have to admit that it is easier to write importers and exporters for the Unreal format.

The engine is able load and animate Unreal Tournament 2004 models:

And it even loads Unreal Tournament 3 models:

Very cool, eventually are you going to get the UT3 animations to work also?

It would be no problem to run UT3 animations. However the UT3 .PSA files don't contain the bones hierarchy. It would require a new trap_R_CheckReferenceBones() function that copies the bones hierarchy from the .PSK file to the animation.

Nice job man! so now we would be able to use unreal 04 models too, that's pretty cool! What about having Half Life SMD or MDL? or is that too much work? It would be much less work for me, lol as all my models previously i made were SMD format :P If not, this is cool as it is!

The advantage of the Doom 3 and Unreal formats over Half-Life's SMD/MDL stuff is that it does not require any preprocessing compilers. You can just load the skeleton + animation keys and start to apply extra stuff like rotating the head bone. It's just easier to use.

Perhaps we could talk to some Unreal community modelers and get them to CC their work so we can use them as player models in XreaL? There are some AAA custom player models for UT3 on various websites.

Hey so, is the *.PSK and *.PSA files compatible with XreaL source fully now? because i'ld love to use it for my project as i am having a pain in the ass with md5mesh and md5anim animating, thanks. :)

The new code needs a bit testing but I think it is fully usable now.

Ok i'm a noob at subversion and sourceforge, so i just wanted to ask is it all updated there? does it update automatically or what? And thanks for making such a great engine!
