I’m suddenly getting a cook error today that prevents me from launching an edit session (if it does manage to “launch” the session, it’s in a completely empty level).

Additional Notes
This is displayed in output log when trying to refresh project size:
LogValkyrie: Display: ProjectSizeRequest::CancelFlow for b32b68b3-4a65-2fc6-af4e-c79a3c5ae1bf - Content (re)cook error errors.com.epicgames.cookplugin.materialerror.

I also have Play In Editor errors that are all essentially the same. I’m unsure if they’re relevant but I’ll include them for context:
AttachTo: ‘/ProjectSky/ProjectSky.ProjectSky:PersistentLevel.BP_Asteria_Oak_Tree_Medium_C_UAID_107C611FCA929D4002_1585275777.StaticMeshComponent0’ is not static , cannot attach ‘/ProjectSky/ProjectSky.ProjectSky:PersistentLevel.BP_Asteria_Oak_Tree_Medium_C_UAID_107C611FCA929D4002_1585275777.ShadowProxyMeshComponent’ which is static to it. Aborting.
I can provide any additional information needed on short notice.
I realize the image uploaded is likely impossible to read. I’ve copied what it says directly from the output log:

Hi @notcreatorguy - are you getting this error message in the editor?
LogMaterial: Error: [AssetLog] ..\..\Plugins\GameFeatures\b32b68b3-4a65-2fc6-af4e-c79a3c5ae1bf\Content\Sky_Dungeon\materials\building_materials\M_building_metal.uasset: Failed to compile Material for platform PCD3D_ES31, Default Material will be used in game. (Node PrecomputedAOMask) Node not supported in feature level ES3_1. SM5 required.
I did not see that in the output log, however going into the material and checking platform stats did reveal that error. I’ve adjusted the material to not use the disallowed node and can now load into an edit session and perform a platform cook. Thank you!
