This tutorial will show you how to use Blender's Decimate feature to reduce poly count in your mesh. It will not show you how to create or map the mesh. Although this tutorial uses an object as the example Blender's decimate feature works the same way on any mesh whether it's an object or a CAS item.
What you will need
Sims 4 Studio
1. Open your mesh in Blender and right mouse click to select it.
2. Click the Object Modifiers tab (looks like a small wrench).
3. Click Add Modifier.
4. Choose Decimate from the modifiers menu.
5. Lower the ratio by sliding your mouse to the left in this box. Alternatively you can enter the ratio you want. You will notice the face count and the Verts | Face counts going down as you reduce the ratio. You will also notice that your mesh begins to become deformed the further down you take the number.
***Note: the second highest LOD is seen at a fairly close distance by people with their graphics settings set low so don't reduce the poly so much that the mesh is really deformed for that LOD. Use EA's .package set up as your guide.***
6. Once the count is lowered to your satisfaction click the Apply button. This must be done in Object Mode. If you don't click the Apply button the change you made will not take effect.
7. If your object has more than one mesh repeat these steps for the other mesh. You can even reduce the poly count of the shadow plane a small amount if it has many vertices in it. Don't forget to click the Apply button.
8. Click File and Save As. Name the new .blend something to set it apart from your high LOD mesh.
9. Back in Studio set the LOD menu to LOD 1 (Medium) and click the Import Mesh button.
Your reduced poly mesh will show up and the counts for Vertices and Faces will be listed below the Import Mesh button. Note that there will be a difference between the numbers here and the numbers shown in Blender. The numbers shown here accurately show the poly count as it will be in the game. If the poly count is still too high you can repeat the decimate process until you end up with a number that you want.
After finishing the medium LOD return to Blender and decimate again for the lower LOD(s). Once your lower LODs are finished you can use these decimated meshes as the base for your lower LOD shadow meshes.
