trouble with relief map

by Felix999 · in Torque Game Engine Advanced · 04/12/2009 (9:44 am) · 12 replies

hello,
i recently got tgea and am trying to get a relief map onto a basic bridge model i'm making with constructor.

i'm using stonewall_d.png and stonewall_n.png from the barricade demo along with the code from materials.cs:

// Materials for the Relief Map example
new Material(Relief_Map_Fallback)
{
   basetex[0] = "~/data/interiors/mountainBridge/stonewall_d";
   bumpTex[0] = "~/data/interiors/mountainBridge/stonewall_n";

   specular[0] = "0.75 0.75 0.75";
   specularPower[0] = 128.0;
   pixelSpecular[0] = true;
   
};

new CustomMaterial(Relief_Map)
{
   texture[0] = "~/data/interiors/mountainBridge/stonewall_d";
   texture[1] = "~/data/interiors/mountainBridge/stonewall_n";

   shader = ReliefShapeShader;
   mapTo = "stonewall_d";
   version = 3.0;

   specular = "0.75 0.75 0.75";
   specularPower = 128.0;
   
   fallback = Relief_Map_Fallback;
};

also i added the code for ReliefShapeShader in client/scripts/shaders:
new ShaderData( ReliefShapeShader )
{
   DXVertexShaderFile     = "shaders/reliefShapeV.hlsl";
   DXPixelShaderFile      = "shaders/reliefShapeP.hlsl";
   pixVersion = 3.0;
};

it kinda works but it's going a bit screwy.
here's a link to a pic which shows what it looks like so far:

if anyone has any ideas i'd be grateful.
thanks in advance.

Before I go on here..I want to tell you I have not used the specific shaders being discussed...nor do I have those textures on hand...so I will go over evident items...

1.
do you have the heightmap in the alpha channel of your normal map ?
alpha channel information: white = high / black = low

2.
shape = model
constructor exports 'interiors'...an interior not a shape/model.

Change your material over to the "reliefinteriorV/P.hlsl" and see if your issue remains. (this is probably not the problem but never doubt anything)

hi eb,
i tried changing to reliefInteriorV/P but no change.
i don't think there's a problem with the alpha channel in the normal map, cause i moved the interior and the materials script into the barricade demo and added the bridge there and it looks fine.

could the difference be that the barricade demo is version 1.7.1 and i'm using version 1.8.1?

thanks for the reply ;)

(sorry english, google translator) The error in this lightmap, first i used this code:

new Material(Relief_Map_Fallback)
{
basetex[0] = "~/data/interiors/Techdemo/stonewall_d";
bumpTex[0] = "~/data/interiors/Techdemo/stonewall_n";

specular[0] = "0.75 0.75 0.75";
specularPower[0] = 128.0;
pixelSpecular[0] = true;

};


// Materials for the Relief Map example

new CustomMaterial(Relief_Map)
{
texture[0] = "~/data/interiors/Techdemo/stonewall_d";
texture[1] = "~/data/interiors/Techdemo/stonewall_n";

shader = ReliefInteriorShader;
mapTo = "stonewall_d";
pixversion = 3.0;

specular = "0.75 0.75 0.75";
specularPower = 64.0;

fallback = Relief_Map_Fallback;
};

and this problem appeared, but when inserting this line in CustomMaterial(Relief_Map):

texture[2] = "$lightmap";

The problem is solved if I don't use the relight, but if I do not use it, the relief shader turns completely dark with no light, using relight, the error back.

Another observation: inverted lightmap

The sunshine is on one side of the map, but relief map it reflects on the other side of object, and side of the map that it reflects the light have the problem of red spots

Marcos, did you ever mail your example files to me...be aware that you must remove the "null" form that email address.
or use: eb7898[at]hotmail[Dot]com

..send some screenshots of other issues too plz.
