So you've decided to start meshing. Congratulations! Here's your gigantic bottle of aspirin and your Certified Masochist badge. Seriously, though, if you want to make meshes, you're going to have to learn how to create 3d models. That may sound daunting, but getting into 3d modeling through Sims 2 is actually easier than learning through other avenues, as you can immediately apply your knowledge to something useful, even if it is just for pixel dolls. Before you can start, you'll need to choose a 3d modeling program. What program you use depends on what you're going to be making, your skill level, and your budget.

Choose Your Path

Though many of the concepts involved in making object meshes and Body Shop meshes are similar, the tools one can use for each type tend to vary somewhat.

Body Shop Meshing

The main difference between Body Shop meshing and most other types of meshing (like with objects) is that Body Shop meshes have a skeleton and bone assignments. Sims 2 bodies have an invisible skeleton with a set of joints. Each vertex in Body Shop meshes is assigned to these joints with different weights. This is what makes the sim's body, hair, and accessories move with their skeleton, and if a mesh is set up in the right way, the movement will be smooth and natural. However you edit, you must have proper bone assignments or your mesh will not function properly.

There are two main types of editing that you'll do with Body Shop meshes: small, and major.

For small edits, like changing breast/waist size, lengthening sleeves a bit, or the like, you have more options for editing than if you want to do more major edits. For small edits of that type, you can use just about any program that properly supports the .obj format along with the MTS2 Meshtool.

Programs that can be used in combination with the MTS2 Meshtool to do small edits include:

• Blender (requires a workaround script/extra work)
• Milkshape

For larger edits, like combining parts of two different meshes, adding parts, and doing major edits of mesh shapes like moving edges beyond animation joints, you will need to have a program that can handle skeletons and vertices assigned to bones in that skeleton.

Programs that can be used to do more extensive edits to Body Shop meshes include:

• 3DS Max - using the .smd format
• Milkshape - most common. Requires the free Unimesh plugins to import and export GMDCs.
• XSI Modtool - using the .smd format. Limited to single groups so only useful for certain edits to bodies.
