What is an IGI file?

An IGI file is an image created by Indigo Renderer or Indigo RT, which are applications for generating photorealistic images. It stores all the information about a 3D scene render in progress. By storing the render progress in an IGI file, you can pause and resume a render in the software at a later time.

More Information

Indigo Renderer and Indigo RT are multiplatform 3D rendering applications. Professional artists in fields such as architecture or prototyping often use the software to create photorealistic images. The apps are very similar, but Indigo RT offers fewer capabilities and is less expensive. Indigo Renderer is also available as a standalone application or as a plugin for other 3D CAD programs.

Rendering scenes in Indigo Renderer or Indigo RT can take a long time and a lot of computing resources. Due to the heavy load of some renders, the software allows you to pause a render and resume at a more suitable time.

How to create an IGI file with Indigo Renderer or Indigo RT

After starting a render, you can save the progress in an IGI file. To create an IGI file with Indigo Renderer or Indigo RT, select Render → Save IGI for resuming.

After selecting this option, Indigo Renderer saves the HDR buffer as an image, and when you load it, the rendering state is restored.

How to open an IGI file

You can open an IGI file with Glare Technologies Indigo Renderer (multiplatform) and Indigo RT (multiplatform). To open the file with Indigo Renderer or Indigo RT, select File → Open or Resume Render from IGI.

NOTE: Since the IGI file stores only the render progress and not the scenes being rendered, you still need the scene file(s) to resume the rendering.
