some textures appearing black in release build

Some textures always do not load in release build.

Everything works well in development build (Screenshot – https://dl.dropboxusercontent.com/u/...8-23-15-30.png) but some textures do not load everytime in release build (Screenshot-- https://dl.dropboxusercontent.com/u/...8-23-15-39.png).

Same textures same levels everytime. Any ideas?

You links got destroyed by shortening.
Maybe you are using a compression format that is not available at the release platform?
