Hi! I recently found out about this blender trick to easily remove splits in a hair mesh when exported. When you export a hair using sims 4 studio, it will be split along the uv borders, but it will also be split on multiple other places, causing weird cuts all over the hair in game.
This tutorial will show you how to keep the hair split between the different parts, while removing the cuts and doubles in the middle of the uv islands. Continued under the cut.
1. Make sure everything is selected, and then select “Remove Doubles”. This will remove all duplicates, but will also remove the splits between the islands, making it look like a big pile of clay.
2. Press space, and then type in “Seams from Islands” and select it. You will se that the edges that you want to be split are now red.
3. Go into edge select mode and press a to deselect everything. Now select one edge that is marked as a seam (an edge that is red). Press shift + g and select “Seam”. Now all the seams will be selected.
4. Now press ctrl + e to pull up the edge panel. Choose “Edge Split”. Now all the seams will be split.
Voila! You have now removed the doubles on the hair while leaving the uv island edges alone! You can now clear the seams and continue working on your hair!!
I hope that you could understand my horrible explaining and find this tutorial useful!!
