Another example of a complex scene in terms of materials. After the conversion, you will have to edit all the materials, since there is not a single hit. My cannon is bronze, the converter says it's not metal, but how does the system know where the metal is, where it's not metal, at the moment it can only be determined by a person. Different behavior of Glossiness and reflections. As a result, you need to tweak and optimize everything. With this quality and accuracy of the conversion, the question arises, and will it also work with Vray? Converting to physical material is a point function, but not as global as it is now.
God forbid if you release this converter to the masses like this, even with all the fixes, but I'm sure there will be a lot of headaches for people, many will not appreciate it.
