GLSL Shader 2 and more textures

[zgerbiak]

Hi.

I have simple shader whit two textures.

But does not load second texture.
I use myTexture2 and he looks like myTexture.

It should look as follows(blender render):

But it looks like:
myTexture
myTexture2

node load:

Code: Select all

String psFileName = "opengl.frag";
        String vsFileName = "opengl.vert";
        IGPUProgrammingServices gpu = driver.getGPUProgrammingServices();
        MyShaderCallback mc = new MyShaderCallback();
        
        int shaderMaterial = (gpu.addHighLevelShaderMaterialFromFiles(
                vsFileName, "vertexmain", E_VERTEX_SHADER_TYPE.EVST_VS_1_1,
                psFileName, "pixelmain", E_PIXEL_SHADER_TYPE.EPST_PS_1_1,
                mc, E_MATERIAL_TYPE.EMT_SOLID
                ));
 mc.drop();
        ISceneNode node1 = smgr.addMeshSceneNode(smgr.getMesh("monkey.b3d"));
        node1.setPosition(new vector3df(0,0,0));        
        node1.setScale(new vector3df(50f,50f,50f));
        node1.setMaterialTexture(0, driver.getTexture("monkey.png"));
        node1.setMaterialTexture(1, driver.getTexture("monkey2.png"));
        node1.setMaterialFlag(E_MATERIAL_FLAG.EMF_LIGHTING, false);
        
        node1.setMaterialTypeByInt(shaderMaterial);

in MyShaderCallback i use:

Code: Select all

 
float[] t = new float[1];
t[0] = 0;
services.setPixelShaderConstant("myTexture", t, 1);
float[] tt = new float[1];
tt[0] = 1;
services.setPixelShaderConstant("myTexture2", tt, 1);
 

maybe it is not correct.

vertex shader:

Code: Select all

uniform mat4 mWorldViewProj;
uniform mat4 mInvWorld;
uniform mat4 mTransWorld;
uniform vec3 mLightPos;
uniform vec4 mLightColor;
 
void main(void)
{
        gl_Position = mWorldViewProj * gl_Vertex;
        
        vec4 normal = vec4(gl_Normal, 0.0);
        normal = mInvWorld * normal;
        normal = normalize(normal);
        
        vec4 worldpos = gl_Vertex * mTransWorld;
        
        vec4 lightVector = worldpos - vec4(mLightPos,1.0);
        lightVector = normalize(lightVector);
        
        float tmp2 = dot(-lightVector, normal);
        
        vec4 tmp = mLightColor * tmp2;
        gl_FrontColor = gl_BackColor = vec4(tmp.x, tmp.y, tmp.z, 0.0);
        
        gl_TexCoord[0] = gl_MultiTexCoord0;
        gl_TexCoord[1] = gl_MultiTexCoord1;
        gl_Position = ftransform();
}
 

fragment shader:

Code: Select all

uniform sampler2D myTexture;
uniform sampler2D myTexture2;
 
void main (void)
{
    vec4 col = texture2D(myTexture, vec2(gl_TexCoord[0]));
    col = col * texture2D(myTexture2, vec2(gl_TexCoord[1]));
    col *= gl_Color;
    gl_FragColor = col * 4.0;
}

What i make bad?

Sorry for my bad english.
