How to edit items(texture) in Sims 4
(was written for Anon on tumblr)
1.Programs which you need: s4pe, CASRecolorTool(i used old version, but you can try new). The best way is extracting with 7z, because some people have bugs with both programs when extracted them with WinRar.
2.Open CASRecolorTool and click Load Package - you need to find CASDemoFullBuild.package, it is here: Origin Games\The Sims 4 Create A Sim Demo\Data\Client.
3.When you will load this package in CASRecolorTool - you will see the list of textures. Choose some from them( lipsticks, hairs can not be exported or will not replace original in game, because CASRecolorTool have a lot of bugs and is unfinished, some clothing has bugs too, as example I can not do non-default recolor for sweater dress, because non-default crashed my CAS). So most of clothes can be edited. Write your Recolor name as example program will recommended you to name MY_ymShoes_SlipperBath_RECOLOR, you can write it as MariaBlackShoes_ymShoes_SlipperBath_RECOLOR, don’t change the name from this part “_ymShoes_SlipperBath_RECOLOR”. because it will crash game.
3.Click Create Recolor and save to some folder created package.
4.Open s4pe and open your saved recolor package.
5.As example you will see CASP and 2-3 UNKN, click on one from UNKN, which has texture with your item and right mouse click - Export to DDS. Name it as you want.
6. Open your dds texture in Photoshop(or GIMP) and begin to draw or modify standard texture. You can also download extracted textures for bodies to understand how it will be look on the sim, or you can downloadextracted bodies and examine your texture in Milkshape on this bodies. Also I wrote tutorial how to extract meshes, so you can extract mesh for this item to Milkshape and see how your texture will look on sim in game.
7. The best way to create clothing or shoes is creating without alpha channel modify(i meant borders of alpha channel), because clothing for Sims 4 has some texture wich looks like normal map in Sims 3 and you can not modify it now( we have not normal stable tool for that) and your sim will be black when you will try to modify it(this texture is one from UNKN in your recolor package).
8.So when you finished your dress texture - save it to dds(DXT5 type).
9.In s4pe with your recolor Click right button of mouse and choose Import from DDS and choose your modified texture. You will see some error text in s4pe in the right part, don’t worry - just save package and it will be ok.
10. Now you can put your recolor package to Mods folder and try in game.
11. Some textures are not editable in CASRecolor (it doesn’t want to create recolor or this recolor will not be look editable). As I know - hairs will show as standard without your editing, cosmetics will not create recolors in CASRecolorTool, so you can only to make default replacement - you need to see my last tutorial How to export meshes from s4pe, by this method you can find textures in s4pe and make default replacement.
