Hi ,im using the tree essential pack to use with foilage but everytime i click a tree it turns grey and when i drag it over to the foilage box there is no texture on it annymore ,idk whats up with that so i tried adding textures thru the editor on the tree mesh and i can put it on the right textures i think but nothing changes ,can anyone help me out ?

If you are importing the mehses then yes you have to make materials with the textures and apply them to the tree. If you are bringing them over from another project example where the trees had textures make sure that you use the migrate button and not just moving the assets from one project to another. Also if you are migrating make sure that you select your projects content directory because if you migrate the folder structure must remain the same. if it changes then your textures and materails will break.
i tried other packages with trees and had the same result ,i can put bark texture on the tree and leaves on the rest but the leaves are just squares with i think leave pictures on them 
well i just unrar the content folder to my project and than i open ue4 again and its there ,but i still need to migrate it ?
Theres two folders in each catagory of trees one material and textures and uasset filles ,do i allso need to copy the config folder in my project ?
please provide a screenshot of the rar contents. depending on who u got it from it sounds like they didnt distribute assets correctly
I meant from the root of the RAR file. Not where you extracted it.
Okay so yes that is a full project. you can not extract that directly to your project. Instead extract that to its own folder and run the Trees.uproject. from there you chould have that persons example project where you can load the trees properly. If you want to add those trees to your own custom project you have to do the migration process from one project to another.
Allright thanks m8 ! Ill check the migrate option now here at my daything ,i get like 2,50euros idk per hour or somethin xD, Hoping i can make some urban terror maps for their upcomming release.
edit: works like a charm migrating is done in a sec ,thanks again for youre quick awnser m8
