3Delight for Softimage has relatively complete support for RenderMaps. The supported properties are: X Res, Path, Refraction, Reflection, Ambient, Diffuse, Diffuse, Specular. Other properties, such as quality properties, are taken from the associated render properties.
The list of properties supported might appear short but 3Delight for Softimage gives you a lot of flexibility by supporting baking of arbitrary user channels. This means that you can bake any desired quantity by using the Store-In shader nodes.
The output render map is always in TIFF format.
