Programmatically configuring materials

A tangible, non-transitory, machine-readable medium storing instructions that when executed by one or more processors effectuate operations comprising:

• obtaining, with a computer system, a three-dimensional virtual world, the virtual world having a world-space coordinate system;
• obtaining, with the computer system, a three-dimensional model for use in the virtual world, the model comprising:
• a mesh having three-dimensional vertices specifying polygons that define a shape of the model;
• and
• a material to be mapped to a selection of one or more of the polygons, the mapping being based on position of the model in the world-space coordinate system, wherein moving the model in the world-space coordinate system causes the mapping of the material to at least one of the selected polygons to move as well;
• and
• a scale of the model within the world-space coordinate system;
• receiving, with the computer system, from a designer creating a game in the virtual world, a placement of the model in the virtual world;
• receiving, with the computer system, from the designer, adjustment of the scale of the model in the world-space coordinate system to configure the model;
• determining, with the computer system, in response to the adjustment of the scale of the model, whether material scaling is locked or unlocked to the model, and, in response, to determining that the material scaling is locked to the model, adjusting the scale of the material in the world-space coordinate system based on the adjustment to the scale of the model to relatively resize the material to the model;
• and
• causing, with the computer system, the model to be rendered in the virtual world with the material mapped on the model based on position of the model in the world-space coordinate system and the material sized in the world-space coordinate system according to the adjustment.
