Is it possible to assign a color to a vertex and ALSO texture that face? (So you get the color blended with the texture.) If so, how do you go about it?

Vertex colors with texturing?

hey all,
I''m sorta a noob at OpenGL, but here goes anyhow

Umm... I can''t seem to get it working. I''m doing:
glEnable(GL_LIGHTING);
glBindTexture(GL_TEXTURE_2D, textures[0]);
glBegin(GL_TRIANGLES);
glNormal3f(xn, yn, zn);
// then for each vertex:
glColor3f(colr, colg, colb);
glTexCoord2f(u, v);
glVertex3f(x, y, z);
glEnd();
However, it simply maps the texture without blending in the colors set with glColor3f. Am I not enabling something I should?

You need to set the texture environment parameter to GL_MODULATE, its probably set as GL_DECAL by default - that overrides the base colour. Take a look at some of the texturing examples on my site...

disable the lighting. if u want to use the lighting + colors use materials (check the red book or the spec for further info)
