zbuffer disabled when shader enabled

category: code [glöplog]

HEJ pouet people!

I got a problem in my lousy code, I enabled the zbuffer and it works perfectly when the shaders aren't enabled (front objects hides objects on the background as usual) but when the shaders are active (I press a key on my code) the zbuffer is instantly disabled and the objects are sorted by their order of creation :(

Any ideas of possible errors I did in teh shaders who can cause that error?

Zavie said it's perhaps because I didn't close properly a FBO but I think I'm ok (but I will try to look deeper in case of).

Thank in advance!

Does your FBO have a depth-buffer?

ermm, I think... NOT :D

I got that to create my FBO (I didn't touched this part myself)

Code:


FBO* GLSL::CreateFBO(int _Width,int _Height,GLenum _Format,GLenum _WrapMode,GLenum _FilteringMode)
	{
	return CreateFBOWithDepthBuffer(_Width,_Height,_Format,GL_INVALID_INDEX,_WrapMode,_FilteringMode);
	}

FBO* GLSL::CreateFBOWithDepthBuffer(int _Width,int _Height,GLenum _Format,GLenum _DepthFormat,GLenum _WrapMode,GLenum _FilteringMode)
	{
	FBO* pResult=new FBO(_Width,_Height,_Format,_DepthFormat,_WrapMode,_FilteringMode);	// create the FBO object
	if(m_pRootFBO!= NULL) m_pRootFBO->m_pPrevious=pResult;	// link it to the list of existing FBOs
	pResult->m_pNext=m_pRootFBO;
	m_pRootFBO=pResult;
	return pResult;
	}

And I create the FBOs like following:

fbo_back=glsl.CreateFBO(screen_w,screen_h);

I'm sure I forgot something, but I'm too lame to know what :D

Hehe. Me too. I actually HAD a z-Buffer, but forgot to glEnable it... ;D
