What is an IGM file?

An IGM file is a material created by Glare Technologies Indigo Renderer, an app for generating photorealistic 3D images. It stores the graphical properties of a material in the XML standard that gives the surface of a 3D object a realistic appearance, such as that of metal, wood, plastic, brick, or liquid. IGM files may be included as part of an Indigo Renderer scene (.IGS file).
