fix for Substance Designer 6 import

IS there a fix for importing Substance Designer 6.0.2 sbsar files into Unity 5.6.0f3 ?

Not currently. Even Unity 2017 doesn’t support Substance Engine 6, so some nodes cannot be imported. Ideally, you can change your engine versioning in Substance Designer to v5 so that nodes that won’t import properly are noted and you can remove them.
