blender 3.3.1 doesn't recognise my qc path

[ChLoe Scott]

im a bit new to blender & source tool maker, I imported 2 models[a character & a part]and stuck the models together,& i made a qc path butt it doesn't recognize the qc,or when it does recognize everything it pops up as error,am i doing somthing wrong?can i fuse 2 models together?how do i properly make a qc path?do blender versions & source tool versions have different ways of understanding paths?is it because i am using an older version of blender?if anyone uses blender 3.3.1 & source tools 3.3,can you help me out & give me some tips?

You need to use Blender 4.1 or later.
