Hello All, Today I am going to show you how to re-texture hair for the sims 4 with Photoshop.
What you need:
Were going to start with something simple. Open S4S and create a standalone recolor. Now choose your hair. I'm going to use the long styled bangs swept back hair, to make things easier as far as making the swatches goes, select the hair and all of its other colors, as shown below. to select multiple items simply click on them.
Save your package in your mods folder. Then go to your desktop or wherever you want it to be and create a project folder. Once we have s4s open and ready we can see that all our colors are already on the list and in the correct swatch order.
Now to get to work. I am going to teach you a very simple method of retexturing. It does not require that you have a drawing pad; however this particular method only works with hairs that have a completely vertical UV map.
Now export the black texture, its the first swatch; and open it in your 2d editor preferably Photoshop.
The first thing we are going to do is make a marquee around the top left corner of the map; this is the corner that is reserved for hair.
Next, right click, and select fill, and choose 50% gray. Next go to Filter, Noise, add noise. use the information given below.
After we add the noise, go to filter, blur, motion blur, and use the information below.
Now we have to make the image darker to add some contrast. go to image, adjustments, curves. Use settings shown below.
We made the image slightly darker, now lets start adding the details.
