It looks like wunderboy's site is down.
In an effort to set up the snazzy WWMT on my snazzy new computer, I found that his site does not exist. I think I'll give your exporter a spin.
Well certainly give it a spin. I've added a lot of new features. The materials are handled a little differently now by default in WW... you control the VMT name based off of the Material name rather than the diffuse bitmap. It all just works with WW SMD Exporter but if using the other exporters you have to turn on the legacy tex names which is in the global settings. Just make sure you are using the altest WW for all that.
I am still able to access the Wunderboy site. I hope he doesn't bring it down as I'm hoping he returns to developments. I'd like to keep collaborating with him.
