..pointlight artifacts..

[Naughty Alien]

..hi guys..im wondering, whats causing Point light to have such artifacts over geometry surface..i havent use anything special, just simple CreatePointLight(), with some given range..it looks like some sort of 'cube' with sides extruded out..

I also get that Naughty Alien.

 

Not sure what it is tho.

 

Thanks

..ahh..its really ruining look of my caves and underground levels..its giving visuals like some sort of cubic map is applied on to surface..sort of..sigh..

I can't tell what is going on in that image. Please post an example that produces this.

..josh example is superbasic and supersimple one...basic use of light, even shadows disabled..i have used it over scene.gmf provided with old heathaze tutorial, just to make sure that im not delusional..here it is code..

SuperStrict

Framework leadwerks.framewerk
RegisterAbstractPath(AppDir)

Graphics(800, 600)

Local fw:TFramewerk

fw = TFramewerk.Create()
If Not fw RuntimeError "Failed to initialize engine."

Include "FreeLook.bmx"

'load a scene
LoadMesh("abstract::scene.gmf")
'Create light
Local light:TLight = CreatePointLight(5)
PositionEntity(light, Vec3(0, .25, 0))
EntityColor(light, Vec4(1, 0.5, 0, 0.1))
EntityShadowMode(light, 0)'disabling/enabling shadows doesnt change a thing



Repeat
 FreeLook(fw.Main.camera, .1)

 fw.Update()
 fw.Render()

 Flip(0)
Until KeyHit(KEY_ESCAPE)
End

 

and its still looking same as before..it seems like creating some sort of rectangle with size of given light range and from each corner of that rectangle, sides are extruded..sort of...weird..

 

here is result on given scene used from tutorials

 

 

also, just side note, doesnt matter is it used with framewerk or not, it does produce same result..

I have never seen this occur. It looks as though you may have shaders mixed up from different versions?

Thanks Josh.

 

It was an older version of the shader.pak that was the problem

 

Thanks
