multitexturing and vertex arrays (solved)

OpenGL OpenGL: Basic Coding
1

EDIT: SOLVED. Both glClientActiveTextureARB and glActiveTextureARB need to be called to set the current texture environment for the texCoord array.

I’m trying to put my heightmap in a vertex array instead of a display list but I can’t get the multitexture to work. Any ideas?

    glColor4f(1,1,1,1);
    glEnable(GL_BLEND);
    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

    glVertexPointer(3,GL_SHORT,0,&mesh_s[0][0][0]);
    glEnable(GL_VERTEX_ARRAY);
    
    glActiveTextureARB(GL_TEXTURE0_ARB);
    glClientActiveTextureARB(GL_TEXTURE0_ARB);
    glEnable(GL_TEXTURE_2D); 
    glTexCoordPointer(2,GL_FLOAT,0,&texcoords[0]);
    glEnable(GL_TEXTURE_COORD_ARRAY);
    glBindTexture(GL_TEXTURE_2D, tex2d[4]);

    glActiveTextureARB(GL_TEXTURE1_ARB);
    glClientActiveTextureARB(GL_TEXTURE1_ARB);
    glEnable(GL_TEXTURE_2D); 
    glTexCoordPointer(2,GL_FLOAT,0,&texcoords[1]);
    glEnable(GL_TEXTURE_COORD_ARRAY);
    glBindTexture(GL_TEXTURE_2D, tex2d[2]); 

    glDrawElements(GL_TRIANGLE_STRIP, 512*2, GL_UNSIGNED_SHORT, &mesh_index[0]);

    glDisable(GL_TEXTURE_2D);
    glActiveTextureARB(GL_TEXTURE0_ARB);
    glClientActiveTextureARB(GL_TEXTURE0_ARB);
    glDisable(GL_TEXTURE_2D);
    glDisable(GL_TEXTURE_COORD_ARRAY);
    glDisable(GL_VERTEX_ARRAY);

Use glActiveTexture with glEnable(GL_TEXTURE_2D).

The client stuff is for, well, client stuff.

Something kinda like this

glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);   
glEnable(GL_BLEND);    
   
glClientActiveTextureARB(GL_TEXTURE0_ARB);    
glTexCoordPointer(2,GL_FLOAT,0,&texcoords[0]);    
glEnableClientState(GL_TEXTURE_COORD_ARRAY);    
  
glClientActiveTextureARB(GL_TEXTURE1_ARB);    
glTexCoordPointer(2,GL_FLOAT,0,&texcoords[1]);    
glEnableClientState(GL_TEXTURE_COORD_ARRAY); 
     
glEnableClientState(GL_VERTEX_ARRAY); 
 
glActiveTexture(GL_TEXTURE0);
glBindTexture(GL_TEXTURE_2D, tex2d[0]);     
glEnable(GL_TEXTURE_2D);   
 
glActiveTexture(GL_TEXTURE1);
glBindTexture(GL_TEXTURE_2D, tex2d[1]); 
glEnable(GL_TEXTURE_2D);

Thanks Hlz. I reordered it like that but it didn’t change what’s happening. Texture0 is getting the texture coordinates from the second glTexCoordPointer which is intended for texture1. Multitexturing is working now (since I removed the clienstate calls) though because texture0 is visible but tinted by what I think is a single pixel from texture1.
