Hi guys, i’m new here.
I’m working on my thesis, i decided to make an interactive presentation of a 3d model, which uses web technologies (i choose Flash + away3d).
In my project i can change the car and rims color.
And also there is a possibility of opening a trunk.
Everything works fine, but i have a BIG problem with shadows and strange mesh behaviour.
First of all i have problems with shadows.
Below i paste my light settings and materials.

sunLight.direction = new Vector3D(-1,-.5,-1);
sunLight.color = 0xEEEEBB;
sunLight.castsShadows = false;
sunLight.ambient = 0.8;
sunLight.diffuse = 1;
sunLight.specular = 1;
scene.addChild(sunLight);
/*

sceneLightPicker = new StaticLightPicker([sunLight]);
filteredShadowMapMethod = new FilteredShadowMapMethod(sunLight);

bodyMaterial.lightPicker = sceneLightPicker;
rimsMaterial.lightPicker = sceneLightPicker;
glassMaterial.lightPicker = sceneLightPicker;

chromeElementsMaterial.lightPicker = sceneLightPicker;
headlightsGlassMaterial.lightPicker = sceneLightPicker;
backlightsGlassMaterial.lightPicker = sceneLightPicker;
signsMaterial.lightPicker = sceneLightPicker;
tyresMaterial.lightPicker = sceneLightPicker;
shadesMaterial.lightPicker = sceneLightPicker;
buildingMaterial.lightPicker = sceneLightPicker;
}
second thing is this weird pixels on the edges of mesh
I suppose it’s because meshes on which it appears were loaded to awayBuilder
body as 2 submeshes ( but in 3ds max its only one mesh with skin modifier and bones to animate the trunk)
tyres also one mesh, (but in away builder it appears as 7 or sometimes even 20 submeshes!!)
I don’t know why that happnens.
because it’‘s many submeshes i had to do something like :
for(var i:int = 0; i<body.subMeshes.length; i++)
{
body.subMeshes[i].material = bodyMaterial;
}
for(var j:int = 0; j<tyres.subMeshes.length; j++)
{
tyres.subMeshes[j].material = tyresMaterial;
}
to add the color to this meshes.
I hope someone can help me.
i attach a zip file with screenshots of my problems
