im trying to use multitexturing with 2 textures.. GL_TEXTURE0 is always rendered just fine... but for some reason GL_TEXTURE1 is never rendered... even if i skip binding GL_TEXTURE0.. what am i doing wrong? im using the glee library and header for extensions...
// INIT FUNCTION
glActiveTexture(GL_TEXTURE0);
Light.LoadRaw("Lightmap.RAW");
Light.CreateTexture(GL_LINEAR,GL_LINEAR,4.0f );
glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);
glActiveTexture(GL_TEXTURE1);
Grass.LoadData("mid2.tga");
Grass.CreateTexture(GL_LINEAR,GL_LINEAR,8.0f );
glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);
void CreateTexture(unsigned int mag, unsigned int min, float samples)
{
unsigned int iTempID;
glGenTextures(1, &iTempID);
glBindTexture(GL_TEXTURE_2D, iTempID);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, mag);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, min);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAX_ANISOTROPY_EXT, samples);
gluBuild2DMipmaps( GL_TEXTURE_2D, GL_RGB, m_uiWidth, m_uiHeight, GL_RGB, GL_UNSIGNED_BYTE, GetData( ) );
SetID( iTempID );
}
// RENDER FUNCTION
glActiveTexture(GL_TEXTURE0);
glBindTexture(GL_TEXTURE_2D, Light.GetID());
glActiveTexture(GL_TEXTURE1);
glBindTexture(GL_TEXTURE_2D, Grass.GetID());
Render mesh with calls to RenderVertex()
inline RenderVertex(CVECTOR& Vertex)
{
glMultiTexCoord2f(GL_TEXTURE0, (float)Vertex.x/(float)m_iSize, (float)Vertex.z/(float)m_iSize);
glMultiTexCoord2f(GL_TEXTURE1, (float)Vertex.x/(float)m_iSize*10, (float)Vertex.z/(float)m_iSize*10);
glVertex3f( Vertex.x, Vertex.y, Vertex.z);
}
