Materials and Textures not Rendering in BGE

Support Modeling
1

I am working on a FPS, cobbled together from parts of other .blend files that were appended to the file. The gun’s materials and textures do not appear to render correctly when playing the game, and only half of the textures for the gun appear during editing.

Can someone point me in the right direction? I can’t seem to upload the blend file, maybe due to its size.

Thanks!

Remove any unneccessary models and enable the ‘compress’ option when you save the file.
You can upload to http://www.pasteall.org/blend/ or million other file hosting sites and tell us the download link
