Custom CAS mesh: Possible to use different texture set ?

Yes, you are meant to transfer all data ( weights, uv_1) not from the hat but the body that the scarf covers.

1. You’re meant to:
- rig the mesh by transferring weights so it animates with the rest of the sim;
- uv unwrap the mesh in uv_0 so that it displays the textures correctly;
- uv unwrap the mesh in uv_1 so that the mesh morphs with the areas of the body it covers;
- vertex paint the mesh to determine according to which variation of deformation map the painted area should morph. It’s important to paint the mesh with the correct color, otherwise it will not morph with the body. If you will not paint it yourself, studio will do it automatically (with 007f00, no matter the category, which is the color for accessories but not anything else). What this color means is that the mesh will morph using the skintight variation but it will not highlight when you hover over the mesh

00ff00 - skintight variation. All morphs beside Details mode ones;
3fff00 - robe-like variation. Meant for skirts and sometimes between the breasts. Prevents the skirts or loose tops from "sinking" between the legs or breasts. The bottom of the skirts will also not be affected by calf and foot morphs;
000000 - disables all dmaps;
007f00 - this color is between 000000 and 00ff00, so you'd expect it to reduce the effect of skintight dmaps by half. I tested it and the area painted with 007f00 morphs just like 00ff00. The only difference is that this area does not highlight when you hover on it. Anyway, this color is used on accessories, the ponytails/jaw-to-ends area of the hair, tips of eyelashes and facial hair;
007f02 - used on root-to-jaw area of the hair;
007F3F - enables Details mode morphs. Used on the hairline, roots of facial hair and eyelashes, piercing;
3F7F00 - used on mermaid tails.

anyway, if the item already exist in-game (scarf as accessories don’t), you can just transfer vertex paint. If not, just manually paint with the correct color


2. I think you are mixing up the maps.
- uv_0 dictates how the textures are displayed. You uv unwrap the mesh manually, then put uvs in the space meant for the chosen category of the item;
- uv_1 dictates how the mesh will morph. For example, the scarf covers the neck area, so it should receive the uvs from the neck area to morph like the neck. So you just transfer the uvs from the nude top

3. You cannot do that for cas items. The other side is meant to be added by duplicating the existing one. Use Solidify modifier, make Thickness very small, then disable Fill rim

hey thanks for the update!
First, let me thank you for the time you took to help, we now understand a lot more, and at the same time it cleared a lot of questionings i had in blender about bones and weights, wich we've bean messing-with for hte last 3 days lol..
Now, the scarf is done, with swatches and thumbnails etc, but one last deatil about it: how to make it replace the hat slot even though it's a necklace?
I use the necklace category for it, but i want the hat to become invisible or unequiped when equiping my scarf. (since i'm using the hat texture space..but...with the new info..perhaps i should just wait for this new feature to be available in s4s?.. planing to release some new and old finished-projects this friday, got my finger-crossed for a s4s update eheh :P

Now, about your last update..this is insane! cant wait to see this implemented in sims4 studio :D

oh thats not what i mean.. i don't want it in the hat category, i want it in the necklace category but still replacing the hat slot while wearing it.

hi, thanks again for all your help!
This is awesome! it fixed my issue of having the wrong textures for the hat while wearing my scarf since i'm using the hat's texture space.. wich i intend to update when s4s receives an update to be able to assign unique textures to CAS item.

Is there a way to decide wich part will win priority? for exemple: as of now, when i equip the scarf and and a hat, the scarf has priority over hats, so the hats simply doesnt show when wearing the scarf. But is there a way to have it the opposite? like, when wearing my neck scarf and then equiping a hat, i would like if the scarf becomes not-visible while the hat is. (it would avoid confusion for users, since people wont necessarly realize why the hat is not appearing when it's equiped..)

For now, until sims4 studio gets updated, is there a way i could tweak a code in my mod to allow unique texture for my scarf knowing that the game now allows it? IT would be insanely cool since it would allow my scarf to be wearable with hats :D

little side question related to this quote..
what if i want to do the opposite for some specific parts? necklaces desapear on some shirts and i cant find wich value in s4s makes it become invisible with only some specific shirts.. (or maybe its related to bones..maybe some shirt have the neck bone?..)
