would this be possible
 

i very much doubt that this would be possible but i want to achive a real terminator effect so iwant to able to press a key and a skelington of a terminator turns ito the liquid trminator then hit the key again and it turns into a t800 with a skin like i said though i think its impossible

Not impossible at all. Just bind ur keys to npc configs.
If you give the link to the models u want, I can mod it for you.

thanks m8 but the stuff i wish to do this with hasnt even been made yet lol see i want to to it with the T-1000 (liquid to man) and the TX (skellington to liquid to woman)

You want the transformation itself? Yeah, that's pretty close to impossible.

Well, one way to do it would be to make a new skin file, and copies of the already existing textures. Then you would make a shader, that turns the entire model into chrome.

So what you would do then, is to make a script, that should when triggered swap between characters, from the "real terminator", to the "liquid" one, and then to the t800.

Bind a key to execute the script. And add wait keys into the script so it would seem as if it's transforming.

could u please make it so the chiss terminator transforms into the t1000 when i press a certain key

Well, like he said you can't actual do a transformation. But like he said, you can bind the model to a key config, so when you press the button you made it they would swap models.... no fancy transformations though.

Lolz, thats all I can add other than, yeah... what Pirate said...

ok i suppose that will have to do then how do i bind models to a key then

It won't be exactly a 'transformation', but i'll describe it anyways.
First you need to know what the model is called, in this example i'll call it t1000.

Ok, in the game console, type:

\bind o playermodel t1000

So, if you press the o button on yer keyboard, you'll change into a t1000.

That's for mp.

For SP do the same, but instead of the model name (t1000) change it to the npc config name.

Thats all I can say for now, I'll need the models myself to give more info.

\bind t models\players\t1000
than
\bind y models\players\t1000\liquid

than you can press t and y to "transform" in t1000 and liquid.
