Hello, if anyone still sees this I am having the same problem with my tiles being grayed out, and was curious if you found a solution? Making things worse is that it only inputs one of the 16 tiles. But like the O.P I cannot select, load, make current, etc
In UE4 I have tried many things to include, but not limited to:
Enabling world comp
Making sure world origin rebasing is active
Making new levels with different streaming distances,
Changing the X, Y, and Z numbers many times from very small to very large numbers.
There is a lot more but I cant remember all of the things I have tried.
In WM I have tried:
Exporting with PNG files for slopes and main output
Exporting with all of them in RAW, RAW16,
Exporting everything the way it’s supposed to be with main output being Raw16 and the slopes as PNG files.
Checking all boxes in the Tiling Options in the “Tiled Build Parameters”
Checking NO BOXES in same area.
Changed tile resolution and tiles per size to the point of making it take an hour and some change to render out successfully.
Going on three days of messing with this and really getting frustrated. Any help would be appreciated.
