Model Making is a little beyond the scope of the site, but I am willing to look at anything you might come up with.
The idea of getting it to open a door is already covered in the tutorial
Security Key's but that uses a key that already exists in HL.
If you want to write a tutorial, all I need are the example RMF's and the text. (
using a simple text editor like NotePad) No need to send the screenies, and please zip the lot together.
As for a coding tutorial, If anyone is really good at it, and can decipher all the complex ideas and turn out some text that makes sense to the New Mapper, then feel free to put it down and send it to me.
