If you want to try switching the models for yourself, like if you want 173 to be a chair, follow the directions below.
Open "SCP Containment Breach folder" (does not have to be extracted)
Open the "GFX" folder and then open "npcs"
Copy the model you want to change ( Ex. copy duck_low_res.b3d)
Rename the model to the identical name of the one you want to replace (Ex. rename duck_low_res.b3d to mtf.b3d)
When doing this step it is important to note the files must be the same type, b3d must be replaced with b3d!
Replace the original model with the renamed one (Ex. replace mtf.b3d with duck_low_res.b3d that was renamed to mtf.b3d)
In most cases the texture file does not have to be copied as well, but if it does do the same thing as in the previous steps. Remember files must be the same type!
Once this has been done load up SCP to make sure no errors occur preventing the game from loading or creating a world.
That should be all, thanks for watching!
