i want to import many png pictures, but after imported, i found the default texture group are World, how to change to UI texturegroup?
Because there are many png pictures, it is impossible to change the texture group one by one in Textreu Editor.
is there any way else?.
Thanks a lot.

Thank you very much.
And is there any way to set the texture group to be UI when importing?

Not sure if there is a way to do it on import, if there is I’m pretty sure it will involve editing engine code
