Here's the problem...
I compiled according to the
instructions a home server, I used the recommended stable version - "2006-07-12 00:00:00 UTC" - and played around with it. CEL, CAL3D and CrystalSpace are also according to the recommended versions. I built the whole thing according to the procedure on two different computers, one running Ubuntu Dapper and the other one Debian Unstable. My best guess is, given the fact that the hardware is nowhere similar, that it's not a hardware issue.
The problem I'm facing acually is the fact that the actor bends according to the texture under him, always having a slanting posture, instead of being upright. The issue is server side, because I connect with the same client (the official one) both to my server and to
Laanx. This seems to happen on any surface that is not perfectly horizontal. Basically I am always perpendicular on the "ground" below me. I can see myself not standing upright, but the other person next to me cannot. Same thing happens to him as well of course. On Laanx, connecting with the same client, everything is fine, on my server I look like this:


The very first time I compiled it, with the cvs data, it worked just fine. After that, I added the official texture files and modified the ".cfg" files under the PS root directory to load the actual data. Started psserver and psnpcclient (the latter giving me a LOT of errors), and then the symptoms decribed above started to appear.
I checked on IRC and some people have had the same issue, but so far we don't know a sollution. Perhaps someone with more experience can tell what the problem is a fix for it. I heard that this has also been an issue on
Laanx a while back, so maybe a dev knows what exactly is going on.
Please tell me if there is more relevant data that I should post.
