Photoshop Alpha Channel Tutorial

This is a super quick crash course tut on how to make clothing parts transparent in Photoshop. Remember opaque is when you want something to completely disappear, white is when you want it to show and gray is if you want like a sheer look. In this tut we are just dealing with white and black. ‘

Remember black conceals, white reveals.

This assumes you know basic steps on how to recolor. If not there are some great tuts on Sims 4 Studio and Lana’s cc Finds under the Tutorial tag.



I am using the same lace pants texture I created from my Slay Jeans V2 set I posted in my group. We don’t need the body template in this tut, but I had it there just to show that it can come in handy when you’re recoloring something transparent or sheer.

The adjustment layer looks like a circle at the bottom

Make sure white is pure white #fffff

Copy your white layer

After you have duplicated your alpha channel, move the first one below it and make sure the eye is shut. Click on the copy layer and select the paint bucket. Make sure pure black is selected in your foreground colors #00000. Pour pure black onto the layer.

Now paste your white layer onto your alpha channel. Make sure the RGB layers are open but make sure the alpha layer is selected. Move the white layer onto the texture from the Layers panel until they perfectly align.

Hide the alpha layer. Make sure the RGB layers are open and selected.

When I copied the white layer the all select was still active, which is fine in case you need to make an adjustment on the alpha again later. After you are happy with it, you can Control D to deselect it.

Once you save your new DDS file to import PS will tell you there are two alphas, and that it is using the alpha layer 1 copy layer, which is what we want.

Import it. We now see our new texture with the lace.

If you want to change the color, you can always go back, create a new color adjustment layer and select whatever color you want onto the texture layer.

Just a tip, don’t use pure black when adding a new color to your texture because the details get lost in game and you can’t see things like folds, pockets, shadows, etc. This has nothing to do with the alpha tut, but purely about recoloring.

Let me know if you have any questions. Thanks and Happy Simming!
