I'm trying to join multiple objects with different materials(Ctrl+J). When I join them they disappear in render view. I was trying to assign materials to different mashes, but it doesn't work! I just don't know what to do
This is my blender file: https://drive.google.com/open?id=1w6xj5XGGIMKtyS8n-4XUSqpCFBkTOaAx
There is flower model and 4 materials: green for flower stem, flower leafs and flowers
I joined flower stem,leafs and flowers but it shows only flower stem in render view.
edit: sorry, I forget to pack textures into .blend file
