Hey guys,
I’m running in to a little error with shading and lighting. If anyone can redirect me to a basic tutorial for this in Away4.x , my problem will be solved but because I can’t find one I’ll post my question here.
This is how far I got
light = new DirectionalLight(-1, -1, 1);
light.color = 0xFFFFFF;
light.castsShadows = true;
light.x = -1500;
light.y = -1500;
light.z = -1500;
myBitmapMaterial.lights = [light];
myBitmapMaterial.shadowMethod = new SoftShadowMapMethod(light);
It all goes well until the last line :|. Adding the shadowMethod somehow spoils all the fun and leaves me with the following error:
Error: Error #3663: Sampler 0 binds an undefined texture.
at flash.display3D::Context3D/drawTriangles()
I hope things sounds familiar to someone here:). I’d love to know how this shading thing works in 4.x… Let me know!
Thanks in advance
Stefan

You need to add this light within the scene before set your shadowMap… try this:
light = new DirectionalLight(-1, -1, 1);
light.color = 0xFFFFFF;
light.castsShadows = true;
light.x = -1500;
light.y = -1500;
light.z = -1500;
view.scene.addChild(light); // addChild before creating shadowMethod
myBitmapMaterial.lights = [light];
myBitmapMaterial.shadowMethod = new SoftShadowMapMethod(light);

That was my first thought! I tried that but it result in the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
The moment I add the light to the scene. The above error occurs. I use the code like following
light = new DirectionalLight(-1, -1, 1);
light.color = 0xFFFFFF;
light.castsShadows = true;
light.x = -1500;
light.y = -1500;
light.z = -1500;
view.scene.addChild(light); // addChild before creating shadowMethod
myBitmapMaterial.lights = [light];
myBitmapMaterial.shadowMethod = new SoftShadowMapMethod(light);
What is wrong? such a basic thing… hmmmm
Thanks for the reply!

You have a object null. Already you created a view?? and a myBitmapMaterial?? Try this:
var view = new View3D(); // You need to create and addChild a View
addChild(view);
var light = new DirectionalLight(-1, -1, 1);
light.color = 0xFFFFFF;
light.castsShadows = true;
light.x = -1500;
light.y = -1500;
light.z = -1500;
view.scene.addChild(light); // addChild before creating shadowMethod
var myBitmapMaterial:BitmapMaterial = new BitmapMaterial(new BitmapData(500, 500));
myBitmapMaterial.lights = [light];
myBitmapMaterial.shadowMethod = new SoftShadowMapMethod(light);
Thanks,

I think I have that pretty much covered. Shall I just give you the code?
It’s already quite long but yeah… than you’ll have a better idea of where the problem could be.
If you can’t see what the problem is I’m gonna reconstruct. As is; I’ll make a very easy class in which the only thing I’ll do is add a plane and apply lighting on it.
But first: I’ll attach the code.
PS: the code is not going to work because I won’t include all the assets.

Maybe your Away3D package is out of date. I tryed with my package and a different jpg. Works ! See the attach zip.
