Additionally, you might need to set a script_targetname key on the entity, to be used as the entity affected by the commands in the script.
About the scripts, something like this should suffice:
 
//(BHVD)

affect ( "Lever", /*@AFFECT_TYPE*/ FLUSH )
{
    rotate ( < X Y Z >, T );
    set ( /*@SET_TYPES*/ "SET_USESCRIPT", "lever_activate_up" );
}
 
Simply make it so that it affects the script_targetname you chose for the lever, and rotate it 90 degrees on the correct axis (totally NOT sure which one it would be - you'll have to experiment on that), in T number of milliseconds. The last command will set the entity usescript to a similar script, but that rotates -90 degrees on the same axis (to switch it back), and sets the entity usescript to the original script - going by the example here, lever_activate_down.
 
Then again... I'm not really experienced with moving objects with BehavEd, so I might be mistaken on a few points.

I recall Minilogoguy also having troubles with rider animations for his AT-RT.

Apparently it's hardcoded.

If the skin supports RGB (check out how it's done with the Trandoshan, it needs an alpha channel), then try putting this line in the NPC file:
 
    customRGBA    random1
 

Sometimes I have this problem with brushes that I manipulated into weird angles. Try making it detail, and see if it works. It generally helps in my case.

I changed absolutely nothing with the textures, I used the ones you packed a few posts earlier. As for the shader, I simply copied the shader code from the base tree branches:
 
models/map_objects/plants/elmleave01
{
    q3map_nolightmap
    q3map_alphashadow
    q3map_onlyvertexlighting
    q3map_vertexScale 0.0125
    cull    twosided
    {
    clampmap models/map_objects/plants/elmleave01
    alphaFunc GE128
    tcMod turb 1 0.01 1.0 1.0
    rgbGen vertex
//    rgbGen lightingDiffuse
    }
}
 
Feel free to ignore the rgbGen lightingDiffuse, it's a fix from another experiment with misc_model_static foliage.

SET_FORCE_INVINCIBLE makes the NPC invulnerable, I think; SET_NO_FORCE makes the NPC immune to Force Powers.

I think Blender keeps the weight when importing player models.

It's not a check, it's a value.
 
LOOP - if it's a ghoul2 model, it will just loop the animation
PLAYER_USE    Player can use it with the use button
INACTIVE    must be used by a target_activate before it can be used
TIE  flying Tie-fighter hack, should be made more flexible so other things can use this if needed

A train is a mover that moves between path_corner target points.
Trains MUST HAVE AN ORIGIN BRUSH.
The train spawns at the first target it is pointing at.
"model2"    .md3 model to also draw
"modelAngles" md3 model's angles <pitch yaw roll> (in addition to any rotation on the part of the brush entity itself)
"speed"        default 100
"dmg"        default    2
"health"    default 0
"noise"        looping sound to play when the train is in motion
"targetname" will not start until used
"target"    next path corner
"target3" what to use when it breaks
"color"        constantLight color
"light"        constantLight radius
"linear" set to 1 and it will move linearly rather than with acceleration (default is 0)
"startframe" default 0...ghoul2 animation start frame
"endframe" default 0...ghoul2 animation end frame

Not completely sure, but I resolved this making the prisoner ignore enemies (SET_IGNOREENEMIES TRUE). I put both strings after SET_ANIM_HOLDTIME_BOTH -1.

/viewpos
/setviewpos <X - West-East> <Y - North-South> <Z - Height> <Angle> sets the position and angle instead.

Maybe this could be of help:

I believe that's an option in the Setup menu. Make sure you have "Force Player Models" and "Defer Player Models" set to Off in Game Options.
