Unity 5.6 materials break when downgrading to Unity 5.5

Graphics Shaders & Materials

Hello,

We’re using an SDK from a vendor that hasn’t yet updated to 5.6, and we need to downgrade our project for 5.5. Everything works fine except our materials lose their texture references, so our scene is basically just a big, complicated mess of white buildings and such.

Is there a way to fix this? I’m thinking that I might have to build a migration tool that parses the YAML or something, but gosh, I really don’t know where to begin with that, and it seems like a multi-day project to build and debug that kind of tool.

Any kind of help would be hugely appreciated!

Pretty sure you can’t easily downgrade that way - Unity 5.6 changed a few file formats, adding new fields to things, and 5.5 won’t know how to change a 5.6 file format into a 5.5 one. You might be able to fix the materials manually, if you are using .txt .meta files, and see if you can figure out the extra fields to delete.
