We’re going to need more information.
Can you provide the specific error message you’re getting, or even your full editor log?
Could not write shader into Library/ShaderCache/0/04f5dd403f04c8bf59e1faf8aefff19e.tmp.
UnityEditor.Toolbar:OnGUI()
and this is error i got
thanks for replying
It looks like unity is having problems writing to a few different places in your project directory - is it actually writable by the current user?
ok ignore my previous reply. it seems i accidentally fixed it by fixing my faulty partition from dual boot error years ago. since my project directory is inside that partition. well i guess pulling all nighter to fix my disks problem really worth the effort. again, thanks to tak for replying. it helps me a lot and give me ease of mind for using the linux editor
i having the same issue on unity 2018.2.0f2! I can’t build my game for PC having 8800 errors and all’s failed to write shader error. This happen when i try to download render pipeline core and highweight render pipeline. I removed but shader errors still happen. And my some shader cache files is broken, whenever i try to delete Library/ShaderCache/8 folder, windows giving me error and the error is “Folder is broken can’t be removed” etc.
