I made a plugin that mimics a render to texture kind of process.
it's not perfect, but the results are good enough to quickly fix any mistakes by hand with a clone tool.
It works with both standard an physical.
Better at organic shapes then hard surface ones. For me it's good enough to use on a professional level.

Let me know what you think of it, bear in mind it's my first ever plugin.
Have done a lot of online research, in the SDK, on c4d cafe, and here on plugincafe!
