Help making a pride flag heart necklace with curvy lines.

Hi. The Sims 4 studio does not support your version of Blender. The item needs to have a cut number assigned to it for S4S to recognize and import it in the package.

This field can appear only in Blender 2.7, 2.76, 2.77 or 2.78. The last is best.
You can still model in 2.8+ but use Blender 2.78 as a bridge. Clone a necklace, export the blend file, open it in 2.78, then File - Append - Object - your necklace meshgroup. Then set type and cut number, save, import in s4s.

I suggest to not use the version of Blender with a different interface than in tutorials for learning. You will just make it harder for yourself.

Initially Create CAS Standalone was for making recolors while Create 3d Mesh included all other resources. As of right now they are the same thing. The developers do not remove one to not confuse people who are used to it.

Everything is important.
Weight paint defines how the mesh will animate. If you do not assign it to the right vertex groups, it will just float, not follow the movement at all.
In your case it would be easier to transfer the weights:
- unfold rig, make top visible and selectable;

- Select it, Shift-select your heart, switch to Weight paint, choose Transfer weights, choose By name;
- Choose Clean tool, scroll up, choose All groups.

- After weight transfer, your heart will have all vertex groups of the reference even if it is not affected by them. To remove them, use this addon. (Type 0 and click Purchase, it's free. Put downloaded file in Blender\2.78\scripts\addons. Install it ( File - Preference - type remove in the search bar - enable the addon - Save user Settings - restart Blender).

Uv_1 map dictates how the mesh will morph during body customization. If the way your item's uvs are unwrapped does not match with the body's, the body will clip into the necklace.
Instead of manually unwrapping, transfer the uvs:
- select your heart ( without the chain ), add Data transfer modifier, choose top as Source object, set the rest like this, apply in Object mode


Vertex paint dictates according to what variation of deformer maps the painted area will morph during body customization. All accessories are vertex painted with 007F00.

Just checked and fixed the blender path in S4S and it's still not working.

I'm sorry to bump this thread again, but I've been busy and upset with school over the past several days and wasn't able to work on the project. Mauvemorn said '- After weight transfer, your heart will have all vertex groups of the reference even if it is not affected by them. To remove them, use this addon.

I don't see a link to the addon here? And they said everything is important so I don't want to just skip it. Idk if it's too much to hope that they see this again or that someone else knows what addon they were talking about, but either would be a huge help and hopefully all I need to finish.
