Lightscape normally requires the creation of a preparation file prior to rendering. This preparation file, or LP file, is based on model geometry generated by a CAD program, and involves a tedious process of orienting surfaces, setting light sources and so forth. Should there be any changes, the user must go back and edit the underlying geometry and build a new LP file from scratch. This interoperability allows the entire design and rendering process to move faster and more interactively. A further, and often overlooked, point about compatibility and interoperability is the ease of customizing a product.
True interoperability is as much a process issue as it is a file-level issue.
Thus, the ability to tailor a product to suit a firm's workflow and business processes, including the interface with other software tools, should at least rank on a par with DWG translation.
