Terrain upgrade filenames are much too long

Unity Engine

I noticed several issues with Win10 itself, e. g. project folder size calculation wasn’t possible anymore. Or when you click “Show in Explorer” on a project file in the Unity Editor, it only opens the explorer, but doesn’t navigate to the file.

I tracked the issue down to the file names being much too long, they exceed the limit of 256 characters.

It happened e. g. after I imported the Meadow Environment from the asset store. Example of an upgraded filename:

Assets/NatureManufacture Assets/Meadow Environment Dynamic Nature/Demo Scenes/_TerrainAutoUpgrade/layer_T_ground_meadow_soil_01_A_SMT_ground_meadow_soil_01_N(4.000,4.000)(0.000,0.000)(0.000,0.000,0.000),0.000,0.000.terrainlayer.meta

That alone is 232 characters, put that into a proper project structure and you go beyond 256 characters easily.

I suggest not creating artificially long filenames which contain coordinates and what not.

Happened also on 2018.3, but that crashed after the import. I thought I’d try with the latest alpha, which didn’t crash.

Thanks for bringing this up. We have a fix for this that is currently being reviewed. Unity Issue Tracker - Upgrader-created terrain layers should use a short hash instead of the collection of numbers (to be more file-system safe)
