My problem is simple,
I have a made a new helmet in geck with the exact same setting/models as the vanilla one.
The only difference is that the helmet I created have an Object Effect.

As the geck setting are practicly identical I am clueless about what would cause that.. The vanilla version works perfectly fine but the one I created doesnt.

Any direction about where to look at would be appreciated.

Sorry for bad english, im french canadian.

Open your mod in GECK, then select
Character>Update FaceGen Model Availability
from the menu, then Save.

That should fix it.

Thanks for your reply.
I loaded my mod and did the FaceGen thing.
A * appeared next to my file name in the window title meaning something have changed.
I saved and tried it ingame and not only it didnt work, the vanilla headgear do the same thing now.

I saw something on the GECK page: http://geck.gamesas.com/index.php/Talk:Update_Facegen_Model_Availability

"Ths function is broken. It will effectively remove all such flags. "

Not sure what to make of it as ive seen modded headgear in game already. :/

Sad...

No, you'll have to reverse the changes made to all vanilla head wear by clicking update facegen availablility in NV GECK by using FNVedit to remove all of the headwear entries out of your mod. Then you'll have to follow these instructions:

"When you open the mod in FNVedit, there's a greyed out listing under Male biped model

Right click and select "add"

After you get a warning about the mod being edited, accept the warning.

Right click in the blank space on the side and select "edit"

You'll get a series of 0's. Delete all of them. Enter just a single "1".

Save and close.

The entry should work now as long as there is no issue with the model."

Thanks I got it working.

Ave Caesar!

a life saver, thanks
