Well, I just plunked the models into an existing code (http://forum.thegamecreators.com/?m=forum_view&t=140248&b=7) to start learning about how to use models in a game. Here's all I'm using to load the car:
load image "DarkMATTER3\Porsche Boxter\porsche.bmp",1,1
load object "DarkMATTER3\Porsche Boxter\Porsche Boxter.x", 1
texture object 1,1
scale object 1,40,40,40
So nothing with limbs. I guess that's a good place to start looking for answers!
The browser that comes with DM3, it lists the limb numbers, and from there I suppose it's just calling commands to rotate and offset them as needed. It just seems odd that the default limb setup for this model pack is so off, but that just prompts you to learn more commands I guess. Thanks!
