I am facing Black shader (Texure missing error) while migrating level into freshly build scene in UE 5.5.4, has any one face the similar issue and has some solution to it.
Steps i am doing.
Opening my build scene Level which is build in UE 5.5.4
Right click on the level >> assetAction >> Migrate
Asset Report window will appear >>> Click ok >>> content folder path selected of freshly Build scene under UE 5.5.4 version >>> ok.
now after opening the freshly build scene file and open the same level which was migrated, is now showing a black shader issue, not a single asset in the level is showing textures.
This issue has popped up from time to time across the community. Since you recently migrated your level, it could mean the materials and/or textures failed to hook up to their targets. Let’s try the following:
Open the migrated level, and make sure that shaders have fully compiled (Window > Developer Tools > Shader Compile Stats)
Check one mesh in the Details panel, and confirm what material is set. If it’s “DefaultMaterial”, you a broken references there
Re-run the migration, but this time point it to a fresh folder inside Content (for example, Content/MigratedTest/). This will avoid conflicts with existing folders
After the new migration is complete, delete folders /Saved and /DerivedDataCache in the target project, re-open, and let shaders rebuild again
If elements are still black, open one of the migrated materials, then re-assign a texture manually to confirm textures came across correctly
