Skinning usually requires a fair amount of work and testing with animations in order to ensure satisfactory results for the skin deformation.

The initial setup is typically automated, say by finding the nearest influence or using “heatmaps”.

Different software packages use different methods, eg, assigning individual vertices and painting the weighting of influence per bone onto the mesh. Skinning involves binding vertices in your mesh to bones, either directly (rigid bind) or with blended influence to a number of bones (soft bind). This is the process of attaching the mesh to the skeleton. * HIPS - UpLeg - Leg - foot - toe - toe_endīiped Skeleton, positioned in T-pose Skinning Possible structures for the hierarchy might be:- * HIPS - spine - chest - shoulders - arm - forearm - hand Given that arms and legs come in pairs, you should use a consistent convention for naming them (eg, “arm_L” for the left arm, “arm_R” for the right arm, etc). The joint/bone hierachy should follow a natural structure for the character you are creating. A minimum of fifteen bones are required in the skeleton. To work with Mecanim, the hips should be the root element of the bone hierarchy. These range from ready-made biped skeletons that you can scale to fit your mesh, right through to tools for individual bone creation and parenting to create your own bone structure. This is the process of creating a skeleton of joints to control the movements of your model.ģD packages provide a number of ways to create joints for your humanoid rig. Skin Mesh, textured and triangulated Rigging Where possible, cap holes, weld verts and remove hidden faces, this will help with skinning, especially automated skinning processes. This will also make it easier to position your rig inside the mesh. This will help allow space to refine polygon detail where you need it (e.g. Since a character typically walks upright on a floor, it is much easier to handle if its anchor point (ie, its transform position) is directly on that floor.

Check the units your 3D package is using and adjust the export settings so that the size of the model is in correct proportion to the cube. Do a test import and compare the size of your imported model with a “meter cube” (the standard Unity cube primitive has a side length of one unit, so it can be taken as a 1m cube for most purposes). A lot can be learned by studying existing 3D character meshes to see how the topology is arranged and why. A poor topology will not allow the model to move without unsightly distortion of the mesh.

The exact nature of a “sensible” structure for your mesh is rather subtle but generally, you should bear in mind how the vertices and triangles of the model will be distorted as it is animated. Although this is a whole subject in its own right, there are a few guidelines you can follow to ensure a model works well with animation in a Unity project. This is the process of creating your own humanoid mesh in a 3D modelling package - 3DSMax, Maya, Blender, etc. There are three main steps in creating an animated humanoid character from scratch: modelling, rigging and skinning.
