This mod has no lipsync.

[Bluegunk]

This mod has a weird head. The author says he took a HPH and another head, converted to LE, used NIFmerge, converted it back to SE. In the process, it's lost its Head Morphs (!), and there's no NIF route to animating the lips.  There's a lot of issues going on it its construction.

 

I used AI to try and fix this and have been down pretty much every path I can think of - and I know nothing about NIF structures. I've moved blocks, branches, deleted / replaced / worked in Nifskope, Outfit Studio and the Creation Kit. 

 

Please. Is there a "NIFologist" out there who can take this head run a quick fix it so the lips move?  I accept - it may not be possible.

 

Thanks.

Are the necessary tri files associated with this HDPT record: RaceMorph, Tri and Chargen Morph?

Hi Traison

 

IN the CK the HDPT has no Tri files. That's the problem. The author said he didn't know how to generate them.  I suspect I won't be able to, either!

[traison]

I imagine the only way these could be generated would be to write an obj parser and create a delta file between the modified and original HPH head. Apply this delta to all obj files in the HPH tris.

 

Work is crazy right now because of oil crisis, war and the orange criminal, so I can't promise anything. obj should be a simple format though if you want to LLM it together in Python.

Thank you. Sadly, I haven't a clue about this - but I'll go and read up about it! Thanks for the idea.

And having read up about it and "talked it over" with AI, It's not worth spending the time on this.

 

Thanks anyway!

1. Go get Animation_Tools_N2 if you don't have it already.
2. Extract the tri files that came with the original head mesh, presumably High_Poly_Head_v1.4_(SE).
3. Locate the unmorphed head obj which should have been in one of the tri files. Most likely named femalehead.obj.
4. Obtain the obj file from the modified HPH head. Remember that the vertex order and count has to be identical to the tri files. Blender and Outfit Studio may be able to do this, if all you have is the nif. Some versions of NifSkope can also save meshes as obj. I do not know which (if any) of these maintain the vertex order when going nif -> obj. If the game crashes, the vertex count was wrong. If your character's face turns into a hedgehog then the order was wrong.
5. Go get Python3 if you don't have it already.
6. Extract my scripts anywhere. Closer to the tri files for less typing.
7. Open a terminal/powershell where the scripts are.
8. Make the delta obj file with make_delta.py.
9. Apply the delta obj file to the obj files extracted from the tri files with apply_delta.py.
10. Rebuild the tri files with Animation_Tools_N2 by drag-n-dropping the included txt files onto it.

$ py .\make_delta.py -h
usage: make_delta.py [-h] source_file target_file output_file

positional arguments:
  source_file
  target_file
  output_file

options:
  -h, --help   show this help message and exit
  

$ py make_delta.py femalehead.obj modified_head.obj delta.obj

 

$ py .\apply_delta.py -h
usage: apply_delta.py [-h] delta_file files [files ...]

positional arguments:
  delta_file
  files

options:
  -h, --help  show this help message and exit


$ py apply_delta.py delta.obj .\my_tri_files\

 

Disclaimer: Not tested. The obj parser is not fully implemented, but it seems to handle the HPH obj files I used as samples.

Hi Traison.  That's a lot to take in! But thank you, I'll give this a roll (probably tomorrow when I'm fresher).

Animation Tools N2.  Is it this one:  https://www.nexusmods.com/skyrim/mods/30162?tab=description  ?

Yes.

[Bluegunk]

OK I'm on this now!

The mod has no head mesh tri file.  SHould I use a copy of the HPH tri file instead?

Seems fine to me.

 

Edit: PM me with your Discord name or something similar if you want faster comms. It's summer and work day here so I'm in and out of the "office" as it were. Gonna take all day if you have to wait an hour for a response.

Thanks for the HPH info. I'll take it from here. I do have a Discord account but if I knew how it worked I'd use it more...lol.  It's the same name, anyhow. There's no rush so leave the discussion here.

Thanks for your help, Traison. 

 

I have an issue with this mod that it actually has two heads merged together in the facegen nif. 

I extracted the OBJ from each of them using Outfit Studio.

Result: I've got 2 obj files: 0_HeadFemaleCustom_Saeong.obj, and VirtualHeadDUPLICATE005.obj.  The contents of each are just a mass of vertices locations.

 

Set ready in one folder I have:

• The two OBJ files above
• The original HPH  femalehead.obj.
• your 3 scripts .   

On the PC I have Python 3.14

 

Now, I don't have any Python ability. It's a language I've never used, only been aware of it, and remain at proto-dufus level at using.  So this is where I come undone.

 

I see your scripts above. But applying them is where I neede a couple of pointers.

You could count the number of lines starting with "v " to get the vertex count. Make sure it matches the line count in femalehead.obj from HPH. If the count is different my python script will most likely throw some out-of-bounds error. I'm not checking of these errors since it wouldn't work in the game anyways.

 

After making the delta obj files, you can do a sanity check by going through the lines starting with "v " looking at how many have been set to 0.0 0.0 0.0. Presumably this modified head will not have all its vertices changed, so a good portion of them should be all zero. If the values are large, similar looking to one of the original obj files, then it's quite likely the vertex order was not maintained in the nif -> obj export.

Usage examples are in the console prints in my post above. Here's what they could look like given your file names:

 

$ py make_delta.py femalehead.obj 0_HeadFemaleCustom_Saeong.obj delta1.obj
$ py make_delta.py femalehead.obj VirtualHeadDUPLICATE005.obj delta2.obj

 

Where $ is the prompt*; yours may be different. If py is no a recognized command (depends on install settings) then try python or python3. If that's also not a recognized command (i.e. Python3 is not in PATH) then you'll have to type out the absolute path to python3.exe instead of "py".

There's a difference of 9 lines with both Saeong files VS the HPH one, plus a break for comment inside each Saeong file.

Which would suggest we'll get a head that looks like it was run over by a semi. And reversed over for good measure.

 

Thanks for the examples - that's easy enough to apply, but if our vertices counts are well off it's probably not going to work?

 

 

 

[traison]

That's fundamentally a different head then. I'm not aware of any other high-poly heads other than HPH. Not going to work until count and order match.

[Bluegunk]

That's what I'm thinking.

 

OK - many thanks for your time and help. Shame this one's a no go, but that's the way of things.

 

I'm sorry to have wasted your time on things. But I did learn a lot about Tris and Obj. That's something to take away.

[traison]

No hints from the author as to what this original HPH mesh was, or where it came from?

 

Edit: Did HPH exist for Skyrim LE? Could go through all known versions to see if one existed at one point with 9 more vertices. I only have one version archived here.

It did but the originating site is dead in the water.   I've probably got the LE version somewhere on disk.  But If I recall the author said he'd built in SSE, converted to LE, used NIFmerge which is LE only, then converted back to SE.

 

It's too much of a nightmare to continue!
