When I load a terrain from T.ED There is already, A texture on it.
My question is, How do I load the model without it loading the textures, So when I start doing a normal map on it. The texture wont get messed up or would someone know how to solve this.

Note: When doing the stages, The texture all merges and is a dark green "No Detail".

What do you mean?

If the object already has a texture then that is usually applied to stage 0. To apply a normal map you would usually apply it to stage 1. Then you need a shader to produce the final result. Alternatively you could try the set bump mapping on command which is simpler but gives less satisfactory results.

Quote: "Note: When doing the stages, The texture all merges and is a dark green "No Detail"."


Unless you use the set blend mapping on command or a shader DBPro will just use the default blending modes (whatever they are ) to combine the result. You really need to post some runnable short code so we can see what you're actually doing.

green not sure what file type your using, but pretty sure you can just remove the materials from the folder where your terrain is loaded and it will solve the problem,or edit the material list in the .x or dbo.

Sorry I did not upload some code sooner.

Note: what you see in the code, May not be close to what it should be. I tried every combination, I could think of.

Media: Normal Map Shader, Was something I got on the forum.

The terrain was made in T.ED, And the basic texture that comes with it. Licensed to me before they stopped selling it. You may use it in your projects.

Uploaded a example code did not add camera controls, As you can see the terrain.

Thanks for posting that.

Several problems there:

1. Your terrain seems to have very strange texture coordinate values. I had to change them to get anything sensible (see attached X file).

2. The shader only requires two textures so your DBPro code should be



(and note that the first two texture stages are numbered 0 and 1).
The other texture will be ignored.

3. The shader should be loaded with texture flag equal to 0:



4. The light direction specified in the shader is pointing up in the air (i.e. positive y) so the terrain is unaffected by the light.

With those fixes (plus possibly others I've already forgotten ) your terrain shows up - but I've no idea how it should look.

That is one of the problems, I had when I tried a different shader. All the textures merged and did not show correct, Looked washed out big time.

Forgot to mention The reason I did not post it with stage 0 in the texture, Is I was in the middle of changing it around and forgot to add it back in. Moved the textures into its own folders.

The way you have it setup works, Well kinda the texture looks like your pic. Washed out, And not even close to what the texture actually is. I thought normal mapping, Was suppose to make the texture pop, So to speak.

You probably need to adjust various things like light position/direction, specular level, texture tiling, and so on.

It would be easier if I could see what you thought it should look like.

Edit Experiment with the scale object texture command - that could be your problem.

Also, what values did you give the texture coordinates of the terrain?

As you can see, It is just a basic texture.

I meant how it should look, not how it looks at the moment.

The picture above, Is what it should look like. And with a normal map, Add deeper looking grass.
