Lego Microgame URP to HDRP

Does anybody know how to change the materials to HDRP I was able to convert most of them but there are some that seam to be locked. They are in a packages folder not in the assets folder. I want to use HDRP to give my game a more realistic look and it looks good so far apart from some pink objects.

The locked ones are likely Materials that are produced as part of the import process of an FBX / Blender file.

These ones you cannot modify because… well, they don’t really exist as an asset: they’re part of the original asset Unity imports.

To get around it, select the Material you cannot change, Ctrl-D to dupe it, and that usually squirts the copy right into the same directory where the FBX is.

Now you can modify that material, then go through your prefabs / scenes and ensure it is used wherever the previous one was.

Or just make a new Material as usual, assign it the same way.
