code:

.......
#include <mtlFx.c>;
.......
.......
action test_object()
{
set(my,POLYGON);
me.ambient=-100;
my.material=mtl_parallax;
}


afterwards i compile my main script, run it and engine crash.
So can you guys correct my "masterpiece" or explain how exacly to use the power of MtlFx.c
Thx

Oh, I forgot to mention that in my level sun_light=0; and there are only dynamic lights

Check the manual under "Predefined Surface Shaders" in the manual.
Do you have all the required skins, of the required type, for that shader?
(I cant help, I never use the built-in shaders)

Hope this helps out some...

I'll check it out, thx
