Maximum 20,000 polygons.
Maximum 4K texture size.
File can have multiple objects.
File can have multiple textures.
If using Maya or 3D Max, select the Embed Media option.
If you want the shoe to participate in simulation and you don't want the pants (trousers) to be simulated inside the shoe - for example, with boots - create a transparent low resolution object that wraps around the shoe and assign a 100% transparent material to that object.
