Been researching of how to extract these. All I found was a 3DS Max Script for the models and a script for the textures that only works in 2009-2014 versions, I don't have access to those versions. And a very rough Noesis plugin. Any help?

DR4 MDL TEX.7z

If you do not use a point cloud you'll face many extra faces and need to find out, why?

(The max script will be the key... The Vertex40Array has to be filled.)

FacesOff=((bigInfo[(findItem names "Combined Indices 2")][3])+(Vertex40Array[i].FaceOff*2))
	
fseek f FacesOff #seek_set

Accidentally and unexpectedly I was able to start an old copy of 3dsmax on my even older machine.

Imported the resulting fbx into Noesis:

only for stride 40, but you can  added other its very simple

Thank you for both of your help, Now I have a new issue occurring. these models will not load in 3ds max and Noesis logs this.

Traceback (most recent call last):

    mdl = rapi.rpgConstructModel()

During handling of the above exception, another exception occurred:

I wouldn't go for patching the maxscript - you can get the parts rather easily:
