AC3D to IFF Conversion: FAQ

What are AC3D files?

Files with the AC3D extension are created using a 3D modelling software program with the same name, currently developed by Inivis. AC3D functions mostly as a tool for creating graphics for games and simulations. AC3D, AC and ACC are proprietary formats of the AC3D software.

What are IFF files?

IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s.
