"WTF are VIDs?": Full VID List and Explanation.

[-SeaboundSaint-]

What are VIDs?:

All "Character Mesh" files (.cmesh) in Saints Row 2 are divided up into sections called "Visual Identifiers" (VID).
Each VID section has a number assigned to it. This is so the game can easily identify that section of the .cmesh.

This system has multiple uses:

---

CUSTOMIZATION ITEMS:

For customization items which the protagonist can wear, VIDs are used to prevent visual clipping between items.

For example;

An open Coat would hide (obscure) the sleeve sections of an Undershirt's .cmesh since they're covered up, but not the front torso sections of the Undershirt because they need to be seen, since the Coat is open.​

The Undershirt itself would be hiding Skin VIDs for the arms and torso, since they are covered up, and don't need to be rendered.​

Via customization_items.xtbl, it is possible to either;

A. Remove VIDs from an item's .cmesh (this is done via "<VID_List>").​

B. Obscure a common VID from multiple other item's .cmeshes when a particular item is worn (this is done via "<Obscured_VID>").​

---

NPCs:

VIDs are also used for NPC Character Meshes. However, they are sectioned differently than customization items, being divided up by the items (whole pieces) they wear.
The VID numbers are inconsistent between NPC meshes, and so cannot be listed in the same way as I have done for the customization items below.

For NPCs, the VID system is used to differentiate which clothing items an NPC spawns with.

For example;

An NPC might have both Pants and Shorts in their .cmesh. The game needs to hide one and render the other. So it might say "Hide VID 10 (Pants)" but "render VID 11 (Shorts)".​

This is done via an NPC's .xtbl/.cvtf file. (More information on this can be found in my NPC Editing In-Depth Guide.)​

CUSTOMIZATION ITEMS FULL VID LIST:

- VID Descriptions marked with an Asterisk (*) are assumed to be what it says, but there's no way of knowing for sure.
- VIDs with no description are either unused or have no .cmeshes which use it in the final game.
