(Please let me know if this thread belongs to Sims 4 discussion instead!)

Hello, I'm currently attempting to convert Sims 4 hairs to the Sims 2, but I have encountered a problem. Every time I import the Blender object file to Milkshape, there are black spots all over the mesh.



I have the feeling that I messed up somewhere in Blender (maybe I don't know how to correctly select all the alpha hair), but I can't think of what exactly. By the way, the method I used to select hair has been pressing A and Shift-clicking everything labeled as a mesh.

Can someone with way more knowledge about Milkshape and Blender help me identify where I went wrong? Thanks in advance!

You need to use the proper OBJ settings in Blender, or you'll get mesh normals all over the place.
Use the exact settings below and you'll usually get a good result (unless it's a pre-existing problem with the mesh)

(where it says 'operator presets' you can save the settings with the +, so it's just one click away every time you want to export OBJs).

And just a tip, but that mesh does look very high poly. You may want to consider if you really want to convert it, or whether it's possible to reduce the polycount (most high-poly meshes end up looking pretty much identical ingame if done properly).
