.PIGM File Extension

A PIGM file is a packed material (.IGM) used by Glare Technologies Indigo Renderer and Indigo RT, 3D visualization applications. It saves an IGM material in a .ZIP format, significantly reducing the material file size and making it more convenient to distribute materials online.

Indigo Renderer is a 3D rendering application that allows artists to create photorealistic images. The software simulates the physics of light to generate images for various purposes, including architectural mockups and film special effects. Indigo Renderer is available as a standalone application or as a plugin for other 3D CAD programs.

Additionally, Indigo RT is also a high-end 3D visualization application. It is similar to Indigo Renderer but offers fewer features and is less expensive.

How to create a PIGM file with Indigo Renderer

You can create a PIGM file with Indigo Renderer when saving a material you want to share or store. To create a PIGM file with Indigo Renderer, select File → New Material, choose File → Save Material As, then select "Packed Indigo Material" from the file type dropdown menu.

You can open a PIGM file with Glare Technologies Indigo Renderer (multiplatform) and Indigo RT (multiplatform). For example, to open the file with Indigo Renderer, select File → Open.

Since PIGM files are Zip-compressed, you can also change the .pigm file extension to .zip, then extract the IGM file stored in the archive with a Zip compression utility, such as File Explorer (Windows) or Apple Archive Utility (macOS).

Indigo Renderer can convert PIGM files to various file types, including the following formats:

• .IGM - Indigo Renderer Material File
• .PNG - Adobe Illustrator Artwork
• .JPG - AutoCAD Drawing
• .TIFF - Drawing Exchange Format
• .EXR - IGES Drawing
