press Import Mesh and choose the newly saved Blender file (the new modified mesh).ġ6. go back to Sims 4 Studio, specifically to your base game item. in this picture, they already have the same number, so it’s all good. remember when i told you to remember the number of cuts? (step 9) check if the number of cuts are the SAME as the base mesh. we should only have one mesh, to do this, shift click all the meshes (including the base mesh) and join them by pressing ctrl + j or the join button, which can be found by toggling Edit (found in left side).ġ3. keep doing this until you achieve your desired look.ġ2. the selected vertices should turn orange. for me, i go to edit mode, right click (the outlines will turn black), press B, then go over the unnecessary parts.
you’ll know it’s the base mesh if any unnecessary patch has disappeared from your model when it is toggled off.ĭelete the vertices of the unnecessary patches of your base mesh. If not, like in this example, find the single mesh from your base item by toggling the eye of each mesh on the right side. by this time you’re supposed to see your model with the base mesh completely covered. then, select all the s4studio_mesh_(no.) available (shift click). press the blend file (the exported mesh) of your pack item, then Object. this can be found under the s4studio CAS tools tab, the one with the GEOM type.ġ0. now that there’s only one mesh, remember its number of cuts. * if there is more than one mesh file, join all the meshes by selecting each one (shift click) and join them by pressing ctrl + j or the join button, which can be found by toggling Edit (found in left side). this can be found under the s4studio CAS tools tab, the one with the GEOM type. * if there is only one mesh file, like in the picture below, usually named s4studio_mesh_1, remember the number of cuts. on the right side, you’ll see the s4studio_mesh_(no.) files. open this mesh, or specifically the base-game available item, in Blender.ĩ. this time we only need the mesh, as we’re going to replace its texture with the one we want, so press Export Mesh.Ĩ. save your package in your chosen folder.ħ. * it is easier if you choose an item that is mostly an undergarment, such as a bra or tank top, or one that can easily be covered by your first chosen item or cc. in this picture you can see that i still chose the same specifications, so that this mesh and the first mesh can perfectly fit. also make sure that this item has the same part type/age/gender/species as your first item. press Cancel then repeat the same steps of going into CAS except this time find an item that is BGC. * in this part you can also add color swatches in case you forgot to choose the other colors (or you just don’t like the available colors).ĥ. if you have your own texture for this specific mesh then you don’t have to save its original texture. make sure the diffuse one is selected (seen just above the Export button). save your package in your chosen folder.Ĥ. you may navigate through the toolbar above to find whatever specific item your'e finding. for this tutorial, first choose the pack-exclusive item. you’ll also see the CAS items from your owned game packs. you’ll be teleported to a wide selection of available CAS items in your game. it doesn’t really matter if the selected button is “Create CAS Standalone” or “Create 3D Mesh”.Ģ.
after a few trials and errors and mixing of steps found online, i’ve finally learned how.ġ. So i’m new to all this cc making and at first i couldn’t find a tutorial that makes my stuff bgc.
