I have an when trying to install the package (UE 4.21.2). I had no problems using the earlier one (I believe it was called foliage_pack) and was quite happy with it (I am a complete beginner and it was great just for some tinkering). When I try to import the vegetation_package by copying files into the content folder UE first asks me to confirm imports (tedious, but workable) then shows a dialog “DataTable options” asking to select DataTableRow type - but no matter what I choose I get a “Failed to parse JSON data.” message. The only thing that I can do is to Cancel - but then all I have on the screen are meshes, without material/texture.
Does it mean the package is incompatible with the newest UE versions? That would be a shame
