Hey, I don't mean to hijack the thread but I figured it's not worth creating a new one as this one is kinda relevant...
I'd been looking forward to giving Trinity a proper go after having the last version that was made public (v3.08f) sitting on my computer for some time, only to find that on second map load (i.e walking through a changelevel trigger or loading map from the console for the second time), the mouse cursor shows that the program seemed to be working (with the spinning circle-thing next to the cursor) for a couple of seconds, then the mod would just quit without any error message. I'm fairly certain this only started to happen after the last Half-Life update a couple months or three back. It's weird too as everything works fine when I load any map for the first time, it's just on any second map load that it crashes. Also, any older version of Trinity (before the shadowmaps were introduced) don't have the issue. I guess maybe Valve modified the rendering engine somehow and this messed something up, but I don't have much programmering experience so I can't tell for sure, nor how to eventually fix it.
Posting this here as maybe someone has more knowledge/experience with Trinity, as I guess the author doesn't support the older versions anymore.
