There must be a problem with the translator with AC13 Artlantis 2.0 output.
When I opened the file on Artlantis, it was fragmented in millions of pieces... i could not even look at the preview to apply shaders and the render was talking 10x longer then the usual, and file was only 5Mb.
I had to save the file as AC12 and then export to Artlantis 2.0 to be able to finish my job.
Has anyone had a problem with that?
