darker textures
I'm noticing a problem of some sort when I multitexture. If I multitexture a triangle with a texture and a solid white texture, it appears darker than if I just use the single texture. Here is what I'm doing...
//for the multitexture
glColor3f(1.0f, 1.0f, 1.0f);
glDisable(GL_DEPTH_TEST);
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glAlphaFunc(GL_GREATER, 0.01f);
glEnable(GL_ALPHA_TEST);
glActiveTextureARB(GL_TEXTURE1_ARB);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, texture[0]);
glActiveTextureARB(GL_TEXTURE0_ARB);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, texture[1]);
glBegin(GL_QUADS);
glMultiTexCoord2fARB(GL_TEXTURE1_ARB, u1,v1);
glMultiTexCoord2fARB(GL_TEXTURE0_ARB, u2,v2);
glVertex3f( x,y,z);
//for the single texture
glActiveTextureARB(GL_TEXTURE1_ARB);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, texture[1]);
glColor3f(1.0f, 1.0f, 1.0f);
glBegin(GL_TRIANGLES);
glMultiTexCoord2fARB(GL_TEXTURE1_ARB, u1, v1);
glVertex3f(x, y, z);
Anyone know why the multitexture is darker than the single texture? I would think if I blended solid white with something, it would be the same as the something.
