COB to PLT Conversion

What are COB files?

COB is a 3D graphics format associated with TrueSpace, a program initially developed by Caligari Corporation, acquired by Microsoft in the late 2000s. TrueSpace had several releases and delivered 3D rendering, modeling and animation features, with its latest edition featuring the possibility of several users to connect via broadband internet and contribute to shared 3D content in real-time. The software has been discontinued starting with 2009.

What are PLT files?
