FAQ

RP to RAD Conversion

What are RP files?

RP is an image format associated with Rainbow Painter, an image processor first released in the early 1990s. The program included a variety of features for image editing and capturing screenshots, and had several upgraded releases in the following years, designed for both Mac OS and Windows platforms. Rainbow Painter has now been discontinued for a few years, so the RP format is considered obsolete and uncommon.

What are RAD files?

The RAD format is supported by a ray tracing application called Radiance, which contains several tools that support lighting simulation and measuring light levels.

Apart from lighting features, they can also save objects and materials, and they serve as input for OCT files that facilitate the scene rendering.
