Hello, I have the new version, but soft shadows are not working, am i doing something wrong?
example:

Code

Include "..\AShadowBBinclude\fps.bb"
Include "..\AShadowBBinclude\Ashadow.bb"
SoftStencilShadows=1
aGraphics3D 640,480,32,2
SetBuffer BackBuffer()

camera=CreateCamera()
PositionEntity camera,0,25,30

light=CreateLight(1)
SetSLight(light,1)
RotateEntity light,45,45,0

EnableSoftStencilShadows (0.002, 5, 500)

Cube=CreateCube(0)
CreateCaster(Cube)
PositionEntity Cube,0,10,0
ScaleEntity Cube,5,5,5

cube2=CreateCube()
EntityColor cube2,100,200,150
ScaleEntity cube2,50,2,50

While Not KeyHit(1)

  TurnEntity Cube,1,1,0
  PointEntity camera,cube

  ARenderWorld(camera)

  Text 5,5,"FPS: "+FPS(50) ; draw fps
  Text 5,20,"ShadowTris: "+ShadowTris ; draw count tris in shadow volumes
  Text 5,30,"RenderTris: "+RenderTris; draw count tris in scene
  Text 5,40,"TimeShadow: "+TimeShadow; draw time for building shadow volumes

Flip 1

End

What am I doing wrong or is my pc not good enough? sad

Hello, can answer late already, but such EnableSoftStencilShadows (0.002, 5, 500) a command in library isn't present.

It isn't present as in the description to library in file: "!!! AShadow_HELP (RUS) !!!.doc"

Than the smog has explained. Without command EnableSoftStencilShadows (0.002, 5, 500) this example works.

P.S.

Has found such function:

EntitySoftSelfShading ( Entity, Mode% )
0 - set from global SoftSelfShading mode (default)
1 - force enabling
2 - force disabling

thus it is necessary to specify by a call of remaining functions parameter SoftSelfShadingMODE=1, for example:
CreateCaster (mesh,files$=0,StencilS_range=0,on=1,S_MeshAlpha#=1, SoftSelfShadingMODE=1, ZfailOFF=0).

Hi!

Quote (dubzilla)

am i doing something wrong?

Yes (:

soft shadows only work in Fake mode (with PostProcess_Render )

try this:

Code

Include "..\AShadowBBinclude\fps.bb"
Include "..\AShadowBBinclude\Ashadow.bb"
;SoftStencilShadows=1
aGraphics3D 640,480,32,2
SetBuffer BackBuffer()

PostProcessInit()

camera=CreateCamera()
PositionEntity camera,0,25,30

light=CreateLight(1)
SetSLight(light,1)
RotateEntity light,35,25,0

EnableSoftStencilShadows (0.002, 5, 50)  ; customize far plane for optimal shadow bluring

Cube=CreateCube(0)
CreateCaster(Cube)
PositionEntity Cube,0,10,0
ScaleEntity Cube,5,5,5

cube2=CreateCube()
EntityColor cube2,100,200,150
ScaleEntity cube2,50,2,50

While Not KeyHit(1)

    TurnEntity Cube,1,1,0
    PointEntity camera,cube

    ARenderWorld(camera,1, 0.7)
    PostProcess_Render(camera)

    Text 5,5,"FPS: "+FPS(50) ; draw fps
    Text 5,20,"ShadowTris: "+ShadowTris ; draw count tris in shadow volumes
    Text 5,30,"RenderTris: "+RenderTris; draw count tris in scene
    Text 5,40,"TimeShadow: "+TimeShadow; draw time for building shadow volumes

Thank you! Now it's working!
But i ran into a problem, the 2d sprites with alpha seem to be affected with shadows.

Look at the picture:

I tried to disable shadow receiving but nothing changed sad

All 2d sprites and other alpha-blend objects must be sets to receivers for correct render.
to simplify - attach the 2d sprites to one pivot and set it as receiver 0

Code

global Global_Alpha_Pivot = CreatePivot()
CreateReceiver Global_Alpha_Pivot,0

EntityParent 2dSprite, Global_Alpha_Pivot
EntityParent alphaBlendGeometry, Global_Alpha_Pivot
....
