   problem: colors blended with textures
  After asking here I found that my problem of weird looking textures were because of previously used colors being blended with the texture and that I should disable blending. But I get the same problem even if I disable blending. Here is my gl initialization code   glViewport(0, 0, 640, 480); glEnable(GL_TEXTURE_2D);// Enable Texture Mapping  // set up light number 1.    glLightfv(GL_LIGHT1, GL_AMBIENT, LightAmbient);  // add lighting. (ambient)    glLightfv(GL_LIGHT1, GL_DIFFUSE, LightDiffuse);  // add lighting. (diffuse).    glLightfv(GL_LIGHT1, GL_POSITION,LightPosition); // set light position.    glEnable(GL_LIGHT1);    glClearColor(0.0f, 0.0f, 0.0f, 0.0f);// This Will Clear The Background Color To Black    glClearDepth(1.0); // Enables Clearing Of The Depth Buffer    glDepthFunc(GL_LESS);   // The Type Of Depth Test To Do    glEnable(GL_DEPTH_TEST);// Enables Depth Testing    glShadeModel(GL_SMOOTH);// Enables Smooth Color Shading    glDisable(GL_BLEND);    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); //To allow transparent textures    glMatrixMode(GL_PROJECTION);    glLoadIdentity();   // Reset The Projection Matrix    gluPerspective(45.0f,(GLfloat)640/(GLfloat)480,0.1f,100.0f); // Calculate The Aspect Ratio Of The WindowglMatrixMode(GL_MODELVIEW);Can somebody find what Im doing wrong?   
  Set the color to white, or TexEnv to something other than MODULATE. DECAL is maybe the right choice not sure though.   ;  If you don't want, that the color of a polygon affects the texture you should make sure that you define the texture enviroment properly:glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);   ;  The problem persists. The white blends with the texture.;  can you post more of your code?especially where you define the textures.   ;  But you have lightning on, right? That means that light info will be added to pixels on your polys. And try to check for glColor3f() or glColor4f() in your code that may interfere with texture color...   ;  Yes, I have some Color3f, to color a polygon a draw before drawing the gui. The full code is here.;Quote:Original post by rogerdvYes, I have some Color3f, to color a polygon a draw before drawing the gui. The full code is here.Where? Are you sure you're not just alpha-blending with a white poly that's all ready in the framebuffer?Edit: Fixed your link.   ;  There is too much code to analyse ;)Before drawing your polygon, do the following: a) disable lightningb) disable coloring materialc) make sure that your texture mode is REPLACEif that doesn't work, then we will try something other...[Edited by - hvor3 on January 11, 2006 8:23:14 AM]
