Hi !
I'm learing about Shader from exaple. and have 2 questions :
1 :
This is the colored texture:

and this is the Normal Texture :

so... WHAT IS THIS ? (Kind of Shader) if you can please share me the fx file :


2 : would someone mind tell me about so0me common Shader ?

This is a blendmap, i think.(Not sure)
You will need it for some terrain shader.

Looks to me like a diffuse reflection map. The brighter the pixel, the more light reflected.

Maybe it's supposed to be a bumpmap?

The second texture is a normal map. You can use it in a shader. After the shader the "main" texture is no more flat, the more darker the texture is the more goes the pixel far. Gives the texture "depth".
The third is like the_mehmaster said...
Hope you understand my bad english....

The second is a Normalmap with information to extant the Normals of a polygon.
The result is a more realistic, more detailed lighting of the surface.
To get a better illusion of the relief wich is described by the normalmap, a height- or depthmap is used to create occlusion through some kind of perpixel offsetmapping. This height/depthmap is normaly stored in the alpha channel of the normalmap. Some image previewer shows you the alphachannal of a texture in white. So the third of your textures is the second map wich contains a height/depthmap the alphachannel.

I had just recieved the email of author !
He said that : the 3rd Texxture is Spec + Bump Mapping... !
can some one tell more about that ?

specular = shiny-ness
and the use as a bump is probably a fallback for normalmapping(or lack of).
I'm guessing this is a somewhat old shader if that is the case written during the transistion from direcX 8 > 9....
But I am no expert.

sometimes the normalmapping is also called bumpmapping and the specmap holds information how strong (and sharp) the specular-highlights are.

Just wondering guys, I don't know much about shaders so the question I have is, What ?.fx shader would a person use to enable this effect?
