Hi! I copy bloom effect from DarkGDK tutorials, and I have a problem. There's a piece of code, and results:

+ Code Snippet

dbMakeCamera    ( 2 );
	//dbColorBackdrop ( 1, 0 );

	// gun
	dbLoadObject			("media\\ak.x", 10 );
	//dbSetSphereMappingOn	( 10,91 );
	dbSetObjectSmoothing(10,100);
	dbSetObjectEmissive (10,75);

	dbLoadCameraEffect ( "media\\Bloom.dbs", 1, 0 );
	dbSetCameraEffect  ( 2, 1, 1 );

	// make a plane and set the quad effect for it
	dbMakeObjectPlane ( 2, 2, 2 );
	dbLoadEffect      ( "media\\Quad.fx", 2, 0 );
	dbSetObjectEffect ( 2, 2 );

	// set up properties for our quad effect
	dbMakeVector4             ( 1 );
	dbSetVector4              ( 1, dbScreenWidth ( ), dbScreenHeight ( ), 0, 0 );
	dbSetEffectConstantVector ( 2, "ViewSize", 1 );
	dbDeleteVector4           ( 1 );
	//dbTextureObject           ( 10, 0, 1 );

There is a two cameras (0 & 2)
What im doing wrong? When I will delete 2 camera, and set camera effect to the main camera (0) i can see black and my weapon. Any help?

Hmm. Where is the Camera2 placed? Is it outside the map? If so, it would constantly be seeing the "DB Blue" color instead of the surrounding area, resulting in that shiny blue gun.

You only posted the setup code...
Nothing bad about it except that

+ Code Snippet

dbMakeVector4             ( 1 );
dbSetVector4              ( 1, dbScreenWidth ( ), dbScreenHeight ( ), 0, 0 );
dbSetEffectConstantVector ( 2, "ViewSize", 1 );

Should be changed to:

+ Code Snippet

dbMakeVector4             ( 1 );
dbSetVector4              ( 1, 1.0f/dbScreenWidth ( ), 1.0f/dbScreenHeight ( ), 0, 0 );
dbSetEffectConstantVector ( 2, "InvViewSize", 1 );

Now it's wierd. When i will look behind myself i see wierd texture. And It's laggy, 26-28 FPS and i don'y see any bloom :/

Camera ID, 0&1

// make a camera and color the backdrop to 0
	dbMakeCamera    ( 1 );
	dbColorBackdrop ( 1, 0 );

dbMakeObjectSphere ( 1, 10 );
	dbLoadImage        ( "media\\detail.jpg", 900);
	dbTextureObject    ( 1, 900 );
	// load an effect for the camera
	dbLoadCameraEffect ( "media\\Bloom.dbs", 1, 0 );
	dbSetCameraEffect  ( 1, 1, 1 );

// make a plane and set the quad effect for it
	dbMakeObjectPlane ( 2, 2, 2 );
	dbLoadEffect      ( "media\\quad.fx", 2, 0 );
	dbSetObjectEffect ( 2, 2 );

// set up properties for our quad effect
	dbMakeVector4             ( 1 );
	dbSetVector4              ( 1, 1.0f/dbScreenWidth ( ), 1.0f/dbScreenHeight ( ), 0, 0 );
	dbSetEffectConstantVector ( 2, "InvViewSize", 1 );
	dbDeleteVector4           ( 1 );
	dbTextureObject           ( 2, 0, 1 );
	
	// ensure camera 1 is set to same position and rotation as camera 0
	dbPositionCamera ( 1, dbCameraPositionX ( 0 ), dbCameraPositionY ( 0 ), dbCameraPositionZ ( 0 ) );
	dbRotateCamera   ( 1, dbCameraAngleX    ( 0 ), dbCameraAngleY    ( 0 ), dbCameraAngleZ    ( 0 ) );

+ Code Snippet

// make a camera and color the backdrop to 0
	dbMakeCamera    ( 1 );
	dbColorBackdrop ( 1, 0 );

	dbMakeObjectSphere ( 1, 10 );
	dbLoadImage        ( "media\\detail.jpg", 900);
	dbTextureObject    ( 1, 900 );
	// load an effect for the camera
	dbLoadCameraEffect ( "media\\Bloom.dbs", 1, 0 );
	dbSetCameraEffect  ( 1, 1, 1 );

	// make a plane and set the quad effect for it
	dbMakeObjectPlane ( 2, 2, 2 );
	dbLoadEffect      ( "media\\quad.fx", 2, 0 );
	dbSetObjectEffect ( 2, 2 );

	// set up properties for our quad effect
	dbMakeVector4             ( 1 );
	dbSetVector4              ( 1, 1.0f/dbScreenWidth ( ), 1.0f/dbScreenHeight ( ), 0, 0 );
	dbSetEffectConstantVector ( 2, "InvViewSize", 1 );
	dbDeleteVector4           ( 1 );
	dbTextureObject           ( 2, 0, 1 );
	
	// ensure camera 1 is set to same position and rotation as camera 0
	dbPositionCamera ( 1, dbCameraPositionX ( 0 ), dbCameraPositionY ( 0 ), dbCameraPositionZ ( 0 ) );
	dbRotateCamera   ( 1, dbCameraAngleX    ( 0 ), dbCameraAngleY    ( 0 ), dbCameraAngleZ    ( 0 ) );

In While:

+ Code Snippet

dbHideObject ( 2 );
		dbShowObject ( 1 );
		dbSyncCamera ( 1 );
		dbPositionCamera ( 1, dbCameraPositionX ( 0 ), dbCameraPositionY ( 0 ), dbCameraPositionZ ( 0 ) );
		dbRotateCamera   ( 1, dbCameraAngleX    ( 0 ), dbCameraAngleY    ( 0 ), dbCameraAngleZ    ( 0 ) );

		// hide the sphere, show the quad
		dbHideObject ( 1 );
		dbShowObject ( 2 );
