For Simblreen I gave out Sims 4 shirts but included the PSD so that you could
1) Add it to any shirt you wanted or
2) Put them on Sims 3 shirts.
Here's how to do that. I'll split this tutorial up into two parts, Sims 3 and Sims 4.
Sims 3
Today we'll be doing this with TSRW as it let's you preview, which is important for beginners. Warning: TSRW is a fickle bitch and can make you want to punch babies sometimes!
You'll need:
Graphics editing program
Photoshop DDS plugin (dunno where to find the gimp one, you'll have to search it up)
Install TSRW and open it up. Wait for it to load, it takes a bit.
Optional: Go to edit > preferences and make sure your expansions are all set right.
Click create new project > clothing and wait for it to load.
Then, the + beside human, then whatever age you want, then gender, then double-click everyday (if that's the category you're looking to get the top or whatnot from)
Find the shirt you want and click it, then click next. Tip: If you type aftop in the bar at the bottom, you can sort through a lot of junk easier.
Name your project and put a title:
Click next, then okay.
This screen! Okay, wait for it to load and then click the texture tab. Scroll down til you find "stencils" and hit the +
Here you have stencil A, B, etc.
If your shirt has a stencil on it right now, click the + beside the stencils until you find one that says "enabled" and "true" beside it. We'll use this.
If your shit doesn't have a stencil on it right now, click "stencil A" and beside enabled hit "false" and change it to "true"
Now scroll up and find "multiplier" should look something like this:
Click edit
Click export and save it somewhere.
Now open your graphics editing program and open the file you just saved. Also, open your PSD (if you're following this from my trick-or-treat thingie), or any other stencil you wanted to use.
(1) On windows hit CTRL A to select all of the stencil (for the PSD's make sure you have the right layer selected!) if on anything else, use the marquee tool and just select everything that way.
Now CTRL C to copy or edit > copy
Now select your multiplier file and hit CTRL V or edit > paste
This is sorta what you should be seeing. CTRL V now or
(2) Now, move the stencil into the middle of the shirt. If you need to resize then hit CTRL T or edit > free transform. Hold shift and drag only from the corners.
Once you've got it in the spot you want it, and the size you want it, delete the background layer. If your stencil was already white, don't worry about doing this part, if your stencil is a color though, do this.
CTRL U or image > adjustments > hue/saturation. Move the Lightness all the way to the right.
Click the new layer button, and then drag that new layer (layer 2) under the stencil layer (layer 1)
Now, grab the paint bucket tool, make sure the foreground color is black and then fill layer 2.
Now merge those two layers by clicking layer 1 and hitting CTRL E or layers > merge layers
You should now only have one layer. Hit CTRL A or the marquee tool and select it all and then CTRL C or edit > copy
Now undo. Undo until you are back to just your stencil, colored if it was originally colored or white if it was originally white.
This will be done with CTRL ALT Z or edit > undo. If you followed the steps right it should take you 5 or 6 undos.
Click your channels tab, and alpha and paste it here (CTRL V or edit> paste)
With your alpha layer selected you should see your white stencil on a black background. Go back to your layers tab, and click your layer. It'll go back to your original stencil.
(3) File > save as > name it stencil or something idc. Save it as a DDS
Go back to TSRW and click edit beside stencil A or whatever one you have enabled.
import > your stencil dds file > open > done
Once it looks the way you want, and make no mistake you may have to go back in and move it around to get it perfect, you can go up to the dropdown and delete the extras. If you want more than once stencil then just choose those and replace the stencils just like you just did with this one. If not, you can select the presets and hit delete.
Likewise, if you need to make more presets you can just hit duplicate.
Now just go to file > export > sims3pack and save it wherever. OR you can go to edit > project contents > export > to package
And that's it. Just install it like you'd normally install your CC and you're good to go.
Sims 4
You will need:
Graphic editing program
And to save myself extra work, you can refer to above when it comes to actually using the graphics editing program.
Install Sims 4 studio, and check "make standalone" and click "create recolor"
When it loads, choose the shirt or whatnot that you want and hit next.
When that loads you want to click "export texture" and save it somewhere. Now you want to open that in photoshop. From then on you'll follow the above tutorial from 1, to 2, then do 3. Then come back to me. No need to make an alpha for this so...
import texture > import the thing you just saved > save if you're done.
There's a more in depth tutorial for Sims 4 studio here. But as always if you have additional questions you can ask me on tumblr (pixelatedzombies.tumblr.com)
I wrote this while extremely tired and in the middle of making dinner so if any part isn't clear feel free to message me and I'll fix it up and answer questions. Thanks for reading.
