This is for anyone who has downloaded the following asset:
https://www.daz3d.com/grovebrook-park
Please rename Predatron_Ripples_01_B.jpg to Predatron_FountainRipples_01_B.jpg in order for that bump map to load via Grovebrook Park Fountain.duf, Grovebrook Park Base Group.duf, and Grovebrook Park Full Scene.duf.
You can find the misnamed file at Runtime\Textures\Predatron\Environments\GrovebrookPark.
@griyar If DS is still asking you to locate the map then that is because it cannot find a file matching the filename that is being called by whichever given DUF file that you are loading. Please make sure that you have renamed the bump file accordingly.
@griyar Your screenshot illustrates the problem exactly how I have explained it to you. You have renamed the file incorrectly to Predatron_FountainRipples_01_B.jpg.jpg instead of to Predatron_FountainRipples_01_B.jpg. If you follow the instructions as I have given them in my initial post then you will stop having the issue that you described.
