Slots keying for state animation with interchangable chlotes

crdmrn

So here's my problem:

I made a character which will need to be able to change clothes so:
-> every bone has multiple slots for the different "layers" of clothing
-> every slot has attachments named as the available clothes for that slot
[Ex: stated that the Chest_Default slot contains the skin level, the Chest_Middle one will have an attachment for every tshirt available, while the Chest_Top one will contain attachments for every jacket, allowing clothes layering]
-> clothes are then grouped by an editor script in unity which uses a custom "Cloth" class with a string clothName variable and a boneSlots List<string> variable containing all the slots for which that cloth is available, so that i can iterate through them calling SetAttachment.

Now I need to have a state animation (hand open, resting, close), but i found out that you can't key slots visibility, therefore i can't make a state animation that is consistent with the clothes-changing structure as apparently the only way to set a slot to be invisible is to make an empty attachment and select that (which I think, if that's really the case, it's really limiting) as the active one.

1) You can animate using Skins.
Each state (open, resting, closed) can be a skin placeholder which you can assign any attachment/image to.
Skins can be mixed and matched at runtime to achieve interchangeable clothes. (no editor preview right now)

2) You don't need an empty attachment. You can key the slot as empty. Just turn off all attachments, then key it.

3) If you're using Unity, this may be interesting: Equips, Customization and Mix and Match

I'm already using skins to change the character skin color, and besides, the goal is not to have something that works for the few exceptions, but something consistent that wouldn't need me to create a new skin for every new piece of cloth i want to place on the body parts that need state animations.
Also, i just found out that you can key the slots to be fully transparent, and if that works when importing to unity as well, it might just be enough... Does it work? 😃

Keying the slot to be fully transparent might not be not ideal.
1) The color would crossfade during mixing (fade-in/fade-out) if you have color keys. and...
2) Even a fully-transparent attachment is still being rendered, which would waste a bit of GPU power (if this is only for one character, this doesn't matter)

If neither are an issue for you, I suppose it would be fine.

Though I have to admit, I don't fully understand what your setup is.

So:
-> every bone has different slots for the different layers of clothing.
-> every slot has an attachment for the different clothes that are available to it (as you can see in the picture).
-> this allow me to group clothes in unity based on the slots they are available for, and to loop through the correct slots when i want to turn on a certain piece of clothes.

As you can see on the second image, i cant use attachments to make states animations (apart from the _default slots, that are used for the skin, and are always active) as i need attachments to turn on and off clothes as shown in image 2 (in image 1 hands only have one pair of gloves atm, but i want something easily scalable).
