I have found the articles describing the python scripts to automatically convert, but the scripts seem to have been deleted, presumably because they have stopped working. For example, looking for materials_cycles_converter.py in the diffusion browser produces the message "This path does not exist at rBAC89bfa619831c. It was deleted in 7d7b8c7d3efc and last existed at rBAC3f433bbe91fd." Is there an alternative script that I haven't found? Or a tutorial?
-- edit: I originally mistakenly used 'textures' where I should have used 'materials' in the title.
