So, heres the situation, my fbo works very well when i only render the color texture, but when i try to render both a depth texture the color texture, the color texture goes all white, so what should i do? Heres the code:

[core]
// Color Texture
glGenTextures(1,texture);
glBindTexture(GL_TEXTURE_2D,*texture);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_NEAREST);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, def.Width, def.Height, 0, GL_RGBA, GL_UNSIGNED_BYTE, NULL);
glBindTexture(GL_TEXTURE_2D,0);


// Depth Texture
glGenTextures(1,depth);
glBindTexture(GL_TEXTURE_2D, *depth);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
glTexImage2D(GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT32, def.Width, def.Height, 0, GL_DEPTH_COMPONENT, GL_FLOAT, 0);
glBindTexture(GL_TEXTURE_2D,0);


// Framebuffer
glGenFramebuffersEXT(1,fbo);
glBindFramebufferEXT(GL_FRAMEBUFFER_EXT,*fbo);

glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_COLOR_ATTACHMENT0_EXT,GL_TEXTURE_2D, *texture, 0);
glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_DEPTH_ATTACHMENT_EXT, GL_TEXTURE_2D, *depth, 0); // <- WHEN I BIND THE DEPTH TEXTURE THE COLOR TEXTURE BECAMES BLANK, ALL WHITE! (also: The depth texture doen't work!)

glBindFramebufferEXT(GL_FRAMEBUFFER,0);

if (glCheckFramebufferStatus(GL_FRAMEBUFFER) != GL_FRAMEBUFFER_COMPLETE)
MessageBox(0,"Looks like we are having problems with Post Processing...","Did it work?!",MB_OK);
[/code]

What should i do? Remembering everything works well without the function i pointed above in the code! And don't blame me for asking for help, already tried google, after 31 websites i gave up...

(ps: This is OPENGL 2.0, not 3.0)

fail [ code ] tag is fail...

And in your rendering loop, after glBindFramebuffer(), you do a glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);? Could be that you don't clear the depth so it doesn't render anything.

did you configure your depth buffer?
do you have it enabled?
did you initiate your depth probably?
could you try different fbo for depth?

Thank you msqrt, i was only cleaning the Color buffer, it's now working perfectly :D

Also: Thanks panic for those questions, next time something happens i will try asking myself to see if i can detect the error :D
