This thread is made to explain how you can easily turn yourself into any model located within the world which you are in.
You simply spawn any model, a barrel an NPC - anything, and follow these few steps.
First create a NPC.
The best NPC’s are: Any bird, Alyx, Kleiner, Monk, Eli, Gman, Headcrabs and the Vortigaunt.
When you have spawned your selected NPC, you type: cl_entityreport 1 in the console.
After you’ve typed it in, a list should pop up. The only thing you want to look for is: ca1_basenpc.
Next to that, there is a number - remember it.
When you’ve got the number type in console: cl_pdump <the number>.
And then a new list will come up, and there you look for m_nModelindex.
Find it and remember the number next to it.
(Then press cl_pdump -1 to remove the list)
When you’ve done all that, enter the final code into the console: ent_fire !self addoutput "modelindex <the number>"
Now you should successfully have turned into your selected model, congratulations.
PS: For this to work, sv_cheats must be 1.
And if you want to see if you’ve been successful, type kill in console.
