Hi! I was asked to make a quick little tutorial for making eyeshadows, but since I can’t half-ass anything, here’s a whole-ass tutorial. Please note that I am in NO WAY an expert and that I’m still learning. My method is probably not the best but it works. There’s probably an easier way to do it! Sims4Studio has a lot of tutorials you can check out to find a method that works for you if this doesn’t.

You need Photoshop + an extension to read DDS files and S4Studio. It would probably work with something other than Photoshop, but it’s what I use and that’s what I’m gonna write about.

Under the cut because it got suuuuper long!!!

Step 1: Open Sims 4 Studio.

Step 2: Choose “Create CAS Standalone”, then click on the big blue CAS button.

Step 3: S4S will show you the catalogue. I like to sort it so Part Type is set to the stuff that I want to make (in this case “Lidschatten” or “Eyeshadow”) then set Game Pack to “Base Game”, which ensures that the item we’ll make is base game compatible. Then just choose any eyeshadow. I usually just take the first one.

Step 4: A new window will open and ask you to name your new package! I usually go NEWCRESTINGwhateveritisNAME. Extra characters like -_.(){] slow your game down, and I feel like putting whatever it is (in this case an eyeshadow) makes sorting it easier. If you wanna name your shadow just eyeshadow1 that’s fine but it will kinda suck for ppl who download it.

Step 5: After you named your eyeshadow, you get to the main S4S screen. We don’t need to do much here for now, just export the texture. To do that, we click export. (I drew a lil arrow) S4S then tells you to save the texture. I usually make a folder per project and save it there under the name “tex” but it really doesn’t matter.

Step 6: Open Photoshop. Make sure you got your DDS plugin installed.

Step 7: Open your texture (in my case called “tex”) The DDS plugin asks you how to load it, click “load using default sizes.”

Step 8: Now you should have your texture in front of you. I like to zoom in to 300-500% depending on what I’m making.

Step 9: Now, on the left there should be a panel called “Channels” or something (my PS is in German so I’m just guessing here). There’s five channels: RBG, Red, Green, Blue, and Alpha. By default, all are selected except Alpha. We’re gonna reverse that so that it looks like this:
