Simplest Mesh Baker is a small plugin that helps you bake several meshes to one in couple clicks.
In addition, it contains a Bone Baker. It is a simple wrapper over SkinnedMeshRenderer.BakeMesh() method, which allows you to convert SkinnedMeshRendered to MeshRenderer considering transformations and poses.
Supported Unity versions: 5.6.3 or higher
To install it, copy the Simplest Mesh Baker folder to your project.
To bake the Meshes, select GameObjects with MeshRenderer or SkinnedMeshRenderer components on it or its children, make a right click and press Bake Meshes.
One Mesh can't contain more than 65,000 vertices, so if source meshes together have more than 65,000 vertices, Simplest Mesh Baker will create several objects.
The plugin will ask you: "Do you want to separate objects with different materials?". If you choose "Yes" Simplest Mesh Baker will bake source objects with different materials to the separated Meshes. If "No" Simplest Mesh Baker will bake all the meshes together and set one of the source materials for it.
Also if several but not all meshed use UVs, Vertex Colors, or Normals Simplest Mesh Baker will ask how to resolve it. You can remove it from all objects or create with default values where it needed.
Then Simplest Mesh Baker will ask you: "Do you want to remove sources?". Click "Yes" if so, or "No" if you want to leave these objects for now.
Then the plugin will show a popup with the number of baked objects.
To use Bones Baker, select GameObjects with SkinnedMeshRenderer components on it or its children, make a right click and press Bake Bones.
The plugin will ask you: "Do you want to remove bones after backing?". Press "Yes" if so, or "No" if you want to leave bones for now.
