Help With Sims 3 to Sims 4 Hair Conversion

Hi. We would need to see the blend file to give any instructions. Right now it seems like the uvs are not aligned

The link does not work, it opens to a blank page

- delete uv_0 and uv_1 with the - button;
- rename the remaining map to uv_0;
- select all uvs with A, choose your image as the background, press S Y 0.5 to shrink the uvs to their original size, then scale them down and align with the texture;

Also, you need to delete and re-transfer weights because the hair should not be assigned to b__HeadNew__ (unless it is from some type of mod or rig replacement). Transfer uv_1 and vertex paint the mesh with 007f00

- delete all weights;

- find some long maxis hairstyle, clone, export, append in the scene, rename to reference;
- select the rteference, shift-select your hair, transfer as shown on the screenshot

You should watch a video tutorial on converting meshes to the sims 4. If you are not familiar with the basic terminology, this will not be a matter of a few screenshots and do-this-do-that
