Thank you dahaga. Really like Howling Abyss scenario from LoL, would fit very good in Northern!

Made a custom sword based on the Soul Edge from Nightmare in Soul Calibur II.
I'm still working improving the particle effects.

Found it with 010 Editor, thanks.

Sorry schlumpf, I'm a bit inexperienced in this field. By modification of the client binary you mean editing WoW.exe?

Ok, this is what I did:
1. Edited the code of:  
                                   src  tools  map_extractor  System.cpp
                                   src  tools  vmap4_extractor  vmapexport.cpp
                                   src  tools  mesh_extractor  MPQManager.cpp

System.cpp


vmapexport.cpp



MPQManager.cpp


2. Compile the tools

3. Run custom mapextractor.exe, then custom vmaps4.exe in WoW directory (you need custom Map.dbc and adt files in your patch)
(Check if detected the custom patch)


4. Move generated files to core folder and use mmaps_generator.exe (the only tool we didn't edit code because get information from the previously data extracted with custom mapextractor.exe, vmap4extractor.exe and vmap4assembler.exe)

Now npcs shouldn't fall through buildings and won't be able to cast through walls.

IMPORTANT NOTES:
-Make sure mmap.enablePathFinding is ON (file: 'worldserver.conf' at your Core folder)
-If in step 3 the tool can't detect your maps make sure everything is written correctly and that there is no other Map.dbc overwriting yours custom. I suggest to either edit the code to make only detect your custom patch or to create another Data folder with your custom patch and the minium MPQs required to make tools working.

Hope this helps you!

Are you using templates? m2 models have hex code, to edit them in an easy way you should use 010 templates: viewtopic.php?f=59&t=828
