Hi,

I'm new to game development and now I'm trying to get familiar with Gamestudio and the hole 3D thing.

The user manual shows how to use shaders (particulary normal mapping) (-> http://www.conitec.net/beta/WED_shaderguide.htm). Paragraph 2 and 3 explain how to apply a material (= shader?!) to an existing surface.

It's working very well, but there's no visible difference if I remove the shader and only use the normal-mapped texture.

Can you explain this? Am I doing anything wrong? Does it actually not matter wether I assign a shader or not?

If thats the case, then im sure you did not apply the shader correctly.
What you mean by "only use the normal-mapped texture"?
Normaly on Block you apply the Deffuse Texture on the Block, and store the normalmap Texture with the ending "_n" in the WAD folder.
For Models, you have to set the normalmap as 2nd Skin.

make sure you add atlest the sun and/or 1 dynamic in the range of the block/model with normalmap shader.

Well I created a new .wad file (mytextures.wad).
Then I chose one texture (tex.tga) and I used the normal map generator to create a normal map texture (tex_n.tga). I added both of them to my mytextures.wad and assigned tex_n to my block (WED).

Then I followed the instructions from the manual to assign the shader. (But it doesn't change the result if I skip this)

There's 1 dynamic light (in range of this block)
I'd post a screenshot but this won't be possible until this evening.

The result of this looks very much like successful normal-mapping (as far as I can judge this).

DONT assign the normalmap to the Block. Just the deffuse map, in your case tex.tga!

Ok, can you explain this?
It seems to work real well this way..

Well if it works real well why do we need to help you??
You cant have normalmappin without assigning a Material, unless you use automaterial?!
Maybe you can post a screenshot, so we can tell if it is normalmapping or not.

Hi,

I'm feeling a little bit stupid right now.
I think I made some kind of fake-normal-mapping or something...

I don't get normal mapping working. I don't have to make any special things in my code, do I?

I've got 2 texture files:
http://www.file-upload.net/download-3393161/floor.tga.html
http://www.file-upload.net/download-3393162/floor_n.tga.html

I added both of them to my .wad file and assigned "floor" (without "_n") to a block. I assigned the shader "mtl_bump" to this block, compiled the map (with 1 dynamic light) and startet my "game".

=> No normal mapping

I don't understand what's wrong with this approach :-(

I'm just guessing here: The file floor_n.tga is maybe not included in the .wmb file and can't be read from the .wad file at runtime. Could you copy the file floor_n.tga to the folder where your main script is?

Hi,

I tried this (but I'm using Delphi and A8 SDK) and copied floor_n.tga into my app-folder.
I also assigned the _n-textures to a dummy block in my .wmp file to force the textures beeing included in the .wmb file.
But both methods did not work.

I'm using the A8 trial version, but normal mapping should be possible with this version, shouldn't it?

Normalmapping in the trail version is only available for i guess 30 or 45 Days, after that i think it become automatically the free version and you cant use shaders anymore.
