I'm trying to add texturing support in my assimp model loading class.

my code follows this structure: http://www.richardssoftware.net/2013/10/loading-3d-models-using-assimpnet-and.html

I dunno why it remains black

here is my code

Model.cpp

http://pastebin.com/kmdiZNSB

model.h

http://pastebin.com/EA4Wf2xa

shader

http://pastebin.com/tPxVTd0u

and when i try to load a model with only material then I get vector subscript out of range error (i.e when model has no textures).

This is how it gets rendered :

This is how it should get rendered:

There is no problem in the model (confirmed.)

I even tried it with manually specifying texture and materials then setting it but no luck. (only material is being used, no texturing is done.)

i dunno why

EDIT: I fixed the issue by drawing that box model first then terrain

but now i have another problem
