Texture in render mode (f12) and game mode (p) doesn't show the same result

Hello, guys
After the last time, I worked on models textures and now encountered another problem.
I was working in view port, render them and see no problem. but after I check them in game mode, I was like WHATTTTTT!?
I checked all the model, well every models got some parts wrong color,

and other model got super mess up, like the shirt inverted, the texture slipped from where it should be.
face texture disappear, etc.

please anyone tell me what did I do wrong and how it should be done.
Thanks in advance!!

Post your blend file to http://www.pasteall.org/blend/
Ensure to first pack all textures into your blend file from the File / External Data menu

http://www.pasteall.org/blend/18648 here!
I packed the texture via that menu, if there’s anything wrong with it, please tell me and I’ll correct it.
I’ll be waiting for your advice : )

oh, more problem, not only the texture was mess up, some part of model disappear when I change point of view

this also happen to houses, building, I think I did something terribly wrong with the texture.

You have some face normals pointing inwards. Flip those so they point outwards either by Ctrl+N on those selected faces or W / flip normals.

Thankyou very much! I’ll be remember this tip :slight_smile:
but still, I can’t find the solution for #4
could you please tell me?

[fixed] for anyone who’s looking for the solution for this problem, I would say that all you need to do for #4 is too make the texture display on both side of face, for me, I goes to edit mode select the faces - mesh - face - solidify. that’s all!
ps. if anyone know how to make it double side by other method please kindly told me, because I’m looking for another way too!
