In Skyrim you can find stuff for the character slider to make certain characters, but I haven't been able to find anything like that for FNV. So how can I make Sunny Smiles on FNV's character creator?

You can edit her directly in the GECK to be a pregen face for character creation. Then when you go to make a character switch through the default faces until you find hers.

If you're on console, you're out of luck.

You can possibly get quite close with the custom settings.

Just wish it was like Skyrim.

Then go play Skyrim.

How to make Sunny Smiles?

Be nice to Cheyenne. That'll get you on her good side and...

Ha! I was thinking along those lines when I saw the title to this thread. I said to meself, "Is that possible? ("sez me to meself sez I)."

You sneaky moggy, you beat me to the joke!

Are you trying to imply the sun smiles in this game if you visit the Cheyenne Natives?

I think the moon smiles with a certain mod, so maybe with the right mods...
