@jcl : Yes, my model already have diffuse map and normal map stored
in skin 1 and skin 2 respectively. My test level is very simple as
follow :

Code:
//
// BansheeTest.c
//
#define PRAGMA_PATH "%EXE_DIR%\templates\images";
//
#include <acknex.h>
#include <default.c>
#include "mtlFX.c";

void main()
{
	video_mode = 8;
	video_depth = 32;
	
	level_load("bansheeTest.wmb");
}


And I've assigned the action "fx_bump" to my model "banshee.mdl"
in WED. Please tell me if there are any further steps that I need
to do in order to show the bumpmapping effect. I can send you the
test level if necessary.

Thank you.
