What is a .IGMESH file?
An .IGMESH file is a type of file used by a computer program called Indigo Renderer, and also by another program called Indigo RT, to help create very realistic pictures using 3D models. Think of it like a detailed instruction sheet that tells these programs how to show the shape of objects in a 3D scene, such as a chair or a tree. This file has all the details about the object's surface, like how smooth or bumpy it is, what color it should be, and how it should look from different angles. It's like a map for drawing the object in a virtual world.
These .IGMESH files work together with another file type called .IGS, which is like the main file for a 3D scene in Indigo Renderer. The .IGMESH files are like the pieces of a puzzle, and the .IGS file is like the picture on the box that shows you what the puzzle looks like when it's finished. Usually, you'll find these .IGMESH files stored in a special folder that has the same name as the .IGS file but with "_meshes" added to the end. Inside this folder, there could be many .IGMESH files, each one named with "mesh_" followed by a bunch of numbers.
To open and work with these .IGMESH files, you need to use the Indigo Renderer program or the Indigo RT program. Both of these are special tools used by artists and designers to make very lifelike images on a computer. Indigo Renderer has more features and can do more things, but it's also more expensive. Indigo RT is a bit simpler and cheaper, and it can also be added onto other design software to give them more capabilities.
So, if you're working on creating or editing a 3D scene using Indigo Renderer or Indigo RT, and you come across a file that ends in .IGMESH, you'll know it's a crucial part of making the objects in your scene look just right.

Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
