Materials and Shaders not working after Packaging

Hi
am I missing something? I can build, play and launch - everything works fine. But when I’m packaging the shaders stop working…plus textures not picking up.

can you please direct me to the right solution?
thanks

Hello VraySchool

It happened to me long time ago while working with foliage. In editor there was no problem but in build there is no material on foliage grasses,bushes… So i researcehed for a long time with out any logical solution but i fixed like this. Open your scene>go to the material with is not working>cut the lines and reconnect them>save all items by combination of CTRL+SHIFT+S> Build and test it again.

Goodluck

Had the same problem, and this worked! Thanks!
