Can't find file for asset error

Ok so I was trying to open a map from the cmedia materials pack and all none of the assets were found. The only things that appeared were the meshes. And although the materials and textures are present in the content browser I can’t apply them because they’re empty. All of the textures in the material editor have a red error tag.

You have a ton of

 [2015.09.06-01.52.51:939][707]LogLinker:Warning: Can't find file for asset '/Game/Textures/Resources/T_MacroVariation' while loading NULL.
[2015.09.06-01.52.51:939][707]LogLinker:Warning: Can't find file '/Game/Textures/Resources/T_MacroVariation'

Linking errors saying the textures dont exist. Did you move anything manually in windows explorer? That will break everything. Sometimes moving stuff in UE4 editor will break everything too.

Did you add the c-media materials package to your project? Is it bought/legit? Does the file referenced exist IE content/textures/resources/T_MacroVariation.uasset?

Try adding it to a fresh blank project, then migrating the files over to your main project. If this works… its your project, if not its the asset package and needs to be re-downloaded.

If that doesnt work try verifiying your engine files and attempting the above, if failure again, complete engine re-install.

Errors like this make me think you moved stuff from users/ade/documents/unreal projects/myproject/content/cmediadadvmats2/data/content/materials/something.uasset somewhere else cause its looking for it in /textures/resources/whateever.uasset which clearly doesnt exist, nor should it

Don’t forget to accept an answer that best clears your question up or answers it so when the community finds your question in the future via search/google they know exactly what you did to fix it/get it going.

Thanks!! I moved it in windows explorer instead of migrating because I didn’t want to create an entire new project, and I guess that’s why it wasn’t working before

We’ve mistakenly moved assets around outside of the UE4 editor and are getting a lot of these warnings. Is there a way to clean them up? I’ve tried cleaning out the Intermediate/Saved/DDC folders, and reinstalling the engine to no avail. Thanks!
