Hi, I use the Evolved's HDR code in my project but I have strange problem (I search for a long time but I've found nothing yet).

So, the Evolved's code work, no problems, but when I use it in my project (a mod for fps creator x9, but I think it change nothing), I have a problem with the camera object (the object that render finally effect at camera). I see it only when I move quickly my mouse (so the camera angle y()), and I just see a port of it on the screen borders.

Can you help me please ?

This a screen of the problem :

This is the HDR update in my project :

set effect constant float HDRobjnum,"blurWidth",HDRblurWidth#
      set effect constant float HDRobjnum,"Brightness",HDRBrightness#
      set effect constant float HDRobjnum+1,"blurWidth",HDRblurWidth#
      set effect constant float HDRobjnum+1,"Brightness",HDRBrightness#
      set effect constant float HDRobjnum+2,"blurWidth",HDRblurWidth#*1.5
      set effect constant float HDRobjnum+2,"Brightness",HDRBrightness#

`````````````````````````````````````
rem update HDR camere 1 to defalt camera
   position camera HDRcamnum,camera position x(),camera position y(),camera position z()
   rotate camera HDRcamnum,camera angle x(),camera angle y(),camera angle z()

`````````````````````````````````````
rem update final HDR screen object to defalt camera
   position object HDRobjnum+2,camera position x(),camera position y(),camera position z()
   rotate object HDRobjnum+2,camera angle x(),camera angle y(),camera angle z()
      move object HDRobjnum+2,9975
      move object left HDRobjnum+2,125
      move object up HDRobjnum+2,75

+ Code Snippet

set effect constant float HDRobjnum,"blurWidth",HDRblurWidth#
      set effect constant float HDRobjnum,"Brightness",HDRBrightness#
      set effect constant float HDRobjnum+1,"blurWidth",HDRblurWidth#
      set effect constant float HDRobjnum+1,"Brightness",HDRBrightness#
      set effect constant float HDRobjnum+2,"blurWidth",HDRblurWidth#*1.5
      set effect constant float HDRobjnum+2,"Brightness",HDRBrightness#

`````````````````````````````````````
rem update HDR camere 1 to defalt camera
   position camera HDRcamnum,camera position x(),camera position y(),camera position z()
   rotate camera HDRcamnum,camera angle x(),camera angle y(),camera angle z()


`````````````````````````````````````
rem update final HDR screen object to defalt camera
   position object HDRobjnum+2,camera position x(),camera position y(),camera position z()
   rotate object HDRobjnum+2,camera angle x(),camera angle y(),camera angle z()
      move object HDRobjnum+2,9975
      move object left HDRobjnum+2,125

When I used this shader I cheated a little to make sure it was always in the right place. Use a sprite made from the image, size it to the size of the screen, paste it to the screen each loop and use "set sprite alpha" to make it transparent.

I thought at this, but why use a box and not sprites ? I'll try. Thanks.

PS: I believe the problem is a question of distance between camera and object.

Looks more like the camera angle is wrong to me but it's hard to say without seeing all the code

HUGE PROBLEM WITH EVOLVED'S HDR....AND HIS WATER ETC.

Normally in DBPro you simply draw the screen with a single camera. When you use Evolved's (or anyone elses) shaders you use additional cameras. In this case the glow is added overlapping the screen taken from some of those additional cameras.

SET CAMERA ASPECT

This must be the same for both cameras or stuff will look out of place. The angles or positions or glow will look wrong and you will pull your hair out double checking everything.

A wide screen monitor needs wide screen cameras.
From the looks of things this probably isn't your 'BIG' problem but you'll likely fix your problem only to find this one.

Your Current Problem:
I borrowed these functions from one of the many HDR demos, and made a few changes. Use these to manage your Camera Plane Object.

Function HDR_Plane_Update( ObjectID As Dword , CameraID As Dword )
    // Orient the Render Target plane to the designated camera
    Position Object ObjectID , Camera Position X(CameraID) , Camera Position Y(CameraID) , Camera Position Z(CameraID)
    Set Object To Camera Orientation ObjectID
EndFunction

Function HDR_Plane_Create( ObjectID As Dword , ImageID As Dword )

Local RTWidth       As Float
    Local RTHeight      As Float
    Local RTDepth       As Float
    Local PixelWidth    As Float

// Grab view size data
    Pick Screen 0 , 0 , 100.0
    RTWidth     = Get Pick Vector X()
    RTHeight    = Get Pick Vector Y()
    RTDepth     = Get Pick Vector Z()
    PixelWidth  = Get Pick Vector Y() / ( Screen Height() * 0.5 )

// Make and setup RT plane
    Make Object Plain ObjectID , 200.0 , 200.0
    Set Object Light  ObjectID , 0
    Set Object ObjectID, 1, 1, 0, 2, 0, 0, 0
    Set Object Texture ObjectID, 2, 0
    `Texture Object ObjectID , ImageID
    `set object light ObjectID,0
    set object transparency ObjectID,1

// Scale and offset to screen
    Scale Limb  ObjectID , 0 , RTWidth, RTHeight , 100.0
    Offset Limb ObjectID , 0 , PixelWidth * 0.0 , PixelWidth * 0.0 , RTDepth
EndFunction

+ Code Snippet

Function HDR_Plane_Update( ObjectID As Dword , CameraID As Dword )
    // Orient the Render Target plane to the designated camera
    Position Object ObjectID , Camera Position X(CameraID) , Camera Position Y(CameraID) , Camera Position Z(CameraID)
    Set Object To Camera Orientation ObjectID
EndFunction

Function HDR_Plane_Create( ObjectID As Dword , ImageID As Dword )

    Local RTWidth       As Float
    Local RTHeight      As Float
    Local RTDepth       As Float
    Local PixelWidth    As Float

    // Grab view size data
    Pick Screen 0 , 0 , 100.0
    RTWidth     = Get Pick Vector X()
    RTHeight    = Get Pick Vector Y()
    RTDepth     = Get Pick Vector Z()
    PixelWidth  = Get Pick Vector Y() / ( Screen Height() * 0.5 )

    // Make and setup RT plane
    Make Object Plain ObjectID , 200.0 , 200.0
    Set Object Light  ObjectID , 0
    Set Object ObjectID, 1, 1, 0, 2, 0, 0, 0
    Set Object Texture ObjectID, 2, 0
    `Texture Object ObjectID , ImageID
    `set object light ObjectID,0
    set object transparency ObjectID,1

    // Scale and offset to screen
    Scale Limb  ObjectID , 0 , RTWidth, RTHeight , 100.0
    Offset Limb ObjectID , 0 , PixelWidth * 0.0 , PixelWidth * 0.0 , RTDepth

The camera aspect are the same (aspect by default, 75.0).

For the functions: the problem isn't the code, I've tested it in an other project, it works, but when I try it in the FPSC source code, the render object is not displayed correctly
