I’m using the Alder tree model in my scene, the one from the Terrain Assets free package. It works fine, including the lighting.
Then I change the file-name of the Alder asset. The lighting immediately gets messed up in the Scene view, and preview, with some areas of the leaves becoming far too bright.
How do I rename the Alder tree asset without ruining its lighting? And why would the Alder tree be having this problem?
Well, I finally found a work-around, but it’s very hacky.
I used a Process Monitor to see what files were changed when I renamed the Alder asset file. After narrowing-down the results, the files in these two folders were the prime suspects: “Library/Previews/25” and “Library/metadata/25”
To make a long story short, I replaced the “/metadata/25” folder with a backup prior to the lighting-problem/asset-rename, which kept the new Asset name while also fixing the lighting problem. (I had to rebuild the project for the changes to show up, though)
