Well, Guys here it is something I have been working on this days, but had the idea long ago on my head. Making a new model for Syl using the Hum_F model as a base, the old syl model isn't bad but it didn't look too coherent in TL2 so now she can be placed as an NPC, a PET or even a skin for the player character since she uses the standard Hum_F skeleton is compatible with all of those animations.
Without further delay here it is. Use it at will, just credit me for the model or not, as long as you don't say you make it, it's fine by me.

This is fantastic
@Anarch16sync thank you so much for this!
My plan is to make a warbound Syl for use with
@doudley 's excellent Warbounds mod. I feel it would be too simple to make her a pet; she is worthy of much more!
@doudley i hope u dont mind if i ask for help in case i need any
Thx Sch! Yes i downloaded that tutorial and made a .pdf
Saw the GIF on Discord and I thought it was absolutely fantastic, amazing work once again!
I will credit you as I'll use this in my project in which Syl appears - kind of

Edit: the model is showing up blank in GUTS, which skeleton is it bound to - the player HUM_F or the NPC HUM_F?
If the model is showing blank it must be since the texture is in .png try converting it to .dds with alpha (DTX 3 compression for example) and that should fix it.
Also the NPC Hum_F and the PC Hum_F use the same skeleton

Edit: I put the .png version of the texture instead of the .dds version since it's better if someone want's to improve the texture.
