Maybe eventually, but at the moment I have WAY too much on my plate as it is. For instance:
I've created a full set of robed textures and robed variants for the elf model. OpenZone 7.4 can fully export it to either .S3D or .XWA, and the test program you're seeing has DLL's to read either format, the sort of DLL's that a client (ahem) could easily use (whether I release the WLD one is something yet to be decided--and I'm leaning against it--but I need one to act as a baseline). The screenshot above is of my zone (windszone) and my elf model, exported to .XWA (in other words, ZERO SOE content).
The DLL work is almost complete, with shaders the last thing to finish (there is partial support at this time but it's not completely there yet). I've also made lots of architectural improvements to OpenZone's engine (which has more capabilities than OpenZone currently uses, hint hint).
I'm trying to get something special done by New Year's but it's a ton of work, and until it's done I don't want to add any new features to OpenZone unless I directly need them. Afterward, though, I wouldn't mind adding .X support to OpenZone if it's not hard to do. One thing you could do to help me would be to find some Delphi code on the net that can read them.
