I don't get it, i do not know how to make a bloom effect to work for the whole level and all objects(1000+).
Until now i got bloom for 1 object or not for all, anyone can help with an example ?

I`m using Bloom from Evolved but if you have an example with another shader i`l switch.

My suggestion would be using for loop to loop through all the objects and apply the shader. But it is kinda stupid.

Theory-When you know everything,but nothing works.
Practice-When everything works,but you don't know why.
Programming merges these two-Nothing works,and you don't know why.

make a plain shove it in front of the camera then grab the contents of the screen and texture the plain with it. Then put shader on it. Then hide plain and do it at again

I have used it with the whole level already ,below is a screenshot from my works. you must make sure the "plane" is in front of your camera when your camera moved .and you should call dbSyncMask(0x00000001) before sync ,otherwise ,I found if D3D rest ,the program will crash. also ,you need to hide and show your all objects one by one.

Here I copied some of my codes about bloom.

Here load the effects and make the camera

int camerafxImage=tkGetImageID();
if ( UserShader){
dbLoadCameraEffect("fx\\bloom.fx",FX_BLOOM,0);
dbLoadEffect("fx\\Quad.fx",FX_QUAD,0);
}

const int vec=1;
if ( UserShader){
dbMakeVector4(vec);
dbSetVector4(vec,dbScreenWidth(),dbScreenHeight(),0,0);
dbSetEffectConstantVector( FX_QUAD,"ViewSize",vec);
dbDeleteVector4(vec);
}

//make cam
dbSetCameraRange (0,5,20000 );
if ( UserShader ){
dbMakeCamera(1);
dbColorBackdrop(1,dbRGB(0,128,0));
dbSetCameraRange (1,5,20000 );
dbSetCameraEffect(1,FX_BLOOM,camerafxImage);
}

Here hide and show all the objects

if ( UserShader ){
dbHideObject(plane);
dbShowObject(box);
dbSyncCamera(1);
player->HideObject();
level->Hide();
dbHideObject(box);
dbShowObject(plane);

dbSyncMask(0x00000001);
dbSync ();
}

here update the plane and camera position

if ( UserShader){
dbPositionCamera(1,dbCameraPositionX(),dbCameraPositionY(),dbCameraPositionZ());
dbRotateCamera(1,dbCameraAngleX(0),dbCameraAngleY(0),dbCameraAngleZ(0));
}

if ( UserShader){
if ( dbObjectExist( plane) ){
dbPositionObject(plane,dbCameraPositionX(0)+dbSin(dbCameraAngleY(0))*500,dbCameraPositionY(0)-dbSin(dbCameraAngleX(1))*500,
dbCameraPositionZ(0)+dbCos(dbCameraAngleY(0))*500 );
dbRotateObject(plane,dbCameraAngleX(0),dbCameraAngleY(0),dbCameraAngleZ(0));
}
