How to extract gr2 with bones for 3d max
I had to first open the *.gr2
Extract the grnreader98 zip and navigate to it in command prompt and enter
cd C:\Users\name user\Desktop\grnreader98.v1.4.0.3.debug
exemple : C:\Users\PRO-PC\Desktop\Name folder grnreader98
press enter
grnreader98.exe "path to re-saved gr2 folder*.gr2" -a -t
which will create the *.smd file.
Install trial of Milkshape 3d and import into Milkshape 3d
(using the first one on list - Half-Life SMD)
then export as a Milkshape Alias FBX.
Import 3D FBX file into 3D Max and you have the skeleton and mesh then re-attach texture.
That's as far as I got but I could not get the mesh to stick to skeleton when I exported to *.FBX.

cd C:\Users\name user\Desktop\grnreader98.v1.4.0.3.debug
Enter
grnreader98.exe "C:\Users\name user\Desktop\grnreader98.v1.4.0.3.debug\barbarian_boss.gr2" -a -t
Enter

Frumos, insa ca o completare->pentru a acoperi partea aceasta

That's as far as I got but I could not get the mesh to stick to skeleton when I exported to *.FBX.

Pentru proportionarea "oaselor" :
* In 3dsmax, select-mode-> all, apoi selectand doar objects(face/mesh, fara nimic din skeleton), click dreapta pe rotatie, iar aici setam doar Z = 90, apoi repetam pentru "move", si setam ca "Absolute world" 0-0-0.
La export, selectam tot(mesh+skeleton)->export selected, altfel modelul va prelua animatiile distorsionat.

* In MilkShape ->Groups->Select(selectam tot)->Rotate, apoi alegand doar axa y, rotim cu 90 de grade. Scheletul se va alinia aproape perfect. Dupa import in 3dsmax, selectand tot, setam rotatia pe axa Z la 270. Asta va alinia si centra modelul in viewport.

Edit: Pentru cei care vor sa treaca peste partea cu

Extract the grnreader98 zip and navigate to it in command prompt and enter
cd C:\Users\name user\Desktop\grnreader98.v1.4.0.3.debug

grnreader98.exe "path to re-saved gr2 folder*.gr2" -a -t
which will create the *.smd file.

am creat o aplicatie micuta, care face exact acelasi lucru, adica folosind acel gr2.exe(eu l-am facut dll), face conversia de la .gr2 la .smd
Aici aveti

Bafta, si spor la 3d-modelling
