You're going to need two things, Oinkerwinkle's Animation transfer and Magos.
1.) Convert the model to .mdl
2.) Go to Oinkerwinkle's Animation Transfer.
3.) Load the model as the base AND the track
4.) Transfer single animation (stand)
5.) Save, and open in Magos.
6.) Adjust the viewport in Magos so its to a view of your liking.
7.) Open up the Camera Manager in Magos
8.) Right click and select create camera from current view.
9.) Go to sequence manager, and rename the second stand animation to be named Portrait ! Read below !
10.) If you want, you can use Vertex Modifier to add a replaceable ID1 background, but that's optional.
11.) Test ingame, and make amends.
If I forgot anything, tell me.
