With modulative shadows and antialias on, shadows are not drawn on the top and left line of the screen. Bug or design?
Does not happen with SaveRenderTexture(). Only the edge of screen is affected, 1 pixel wide.
(Windows 10 x64, PB 5.31+5.50)

Code: Select all

InitKeyboard() : InitEngine3D() : InitSprite()

AntialiasingMode(#PB_AntialiasingMode_x2)

ExamineDesktops()
OpenScreen(DesktopWidth(0),DesktopHeight(0),32,"",#PB_Screen_NoSynchronization)

WorldShadows(#PB_Shadow_Modulative,1000,RGB(64,64,64),512)

AmbientColor(RGB(64,64,64))
a=CreateLight(#PB_Any,RGB(255,255,255),1000,300,00,#PB_Light_Directional) : LightLookAt(a,0,0,0)
CreateCamera(#PB_Any,0,0,100,100)

texture=CreateTexture(#PB_Any,16,16)
StartDrawing(TextureOutput(texture))
    Box(0,0,16,16,RGB(255,255,255))
StopDrawing()
material=CreateMaterial(#PB_Any,TextureID(texture)) : mesh=CreateCube(#PB_Any,1)
a=CreateEntity(#PB_Any,MeshID(mesh),MaterialID(material),0,-2,0) : ScaleEntity(a,100,1,100)
entity=CreateEntity(#PB_Any,MeshID(mesh),MaterialID(material),0,0,-8)

Repeat
    ExamineKeyboard()
    If KeyboardReleased(#PB_Key_Escape)<>0
        Break
    EndIf
    RotateEntity(entity,0.4,0.5,0.6,#PB_Relative)
    RenderWorld() : FlipBuffers() : Delay(10)
ForEver
End

Hi
i have tested your code in win7 and winxp with PB 5.31 and the shadow seems normal like this picture:

the same shadow in PB 5.43.
if we add this in line 12:

Code: Select all

cam=CreateCamera(#PB_Any,0,0,100,100)
MoveCamera(cam, 0,70, 0.00001, #PB_Absolute)
CameraLookAt(cam,0,0,0)

so to position the camera high away over the scene we will see the whole shadow from above,

note: the 0.00001 because we can't see anything when we use absolute zero. may be Comtois look at this situation

try this

Code: Select all

cam=CreateCamera(#PB_Any,0,0,100,100)
CameraFixedYawAxis(cam, #False)
MoveCamera(cam, 0,70, 0, #PB_Absolute)
CameraLookAt(cam,0,0,0)
