Material missing

Using 4.6.1. Packing a simple version of the Shooter game. It has some Bots and some DM’s. One of DM’s has a red material on it and other a blue material. When I start the game in the Editor the DM’s look good. When I package the game the material on the second DM is gone.

Unreal is this a bug in 4.6.1.

  1. open the output log during the packaging process and check if you can find any warnings/errors (Show Log button)
  2. make sure that your material is in the content folder of your project
  3. probably it helps when you enable bUseStaticLighting = true in your material (Materials Missing in Standalone or Packaged Game - Rendering - Epic Developer Community Forums)
