but not pixel shaders, we create a new material which only uses the
vertex shader, and no pixel shader. Otherwise, if we would tell the
engine to create this material and the engine sees that the hardware
wouldn't be able to fullfill the request completely, it would not
create any new material at all. So in this example you would see at

Now lets create the new materials. As you maybe know from previous
examples, a material type in the Irrlicht engine is set by simply
changing the MaterialType value in the SMaterial struct. And this value
is just a simple 32 bit value, like video::EMT_SOLID. So we only need
the engine to create a new value for us which we can set there. To do
this, we get a pointer to the IGPUProgrammingServices and call
addShaderMaterialFromFiles(), which returns such a new 32 bit value.
That's all.
The parameters to this method are the following: First, the names of
the files containing the code of the vertex and the pixel shader. If
you would use addShaderMaterial() instead, you would not need file
names, then you could write the code of the shader directly as string.
The following parameter is a pointer to the IShaderConstantSetCallBack
class we wrote at the beginning of this tutorial. If you don't want to
set constants, set this to 0. The last paramter tells the engine which
material it should use as base material.
To demonstrate this, we create two materials with a different base
material, one with EMT_SOLID and one with EMT_TRANSPARENT_ADD_COLOR.
