Hello here is the question. When i use Directional Light in my scene i recieve black solid shadows. I can increase material.ambient parameter to make them more lighted, but this spoils the look of my scene, makes it toy-like. I use 4 lights to light up my model. First light casts shadow. So how can i make my rest 3 light affect the black shadow areas as supposed to happen in real life?
The code i use:

tmp.specular = .6;
        tmp.gloss = 20;
// tmp.ambient = .5;
        tmp.shadowMethod = new TripleFilteredShadowMapMethod(_light);
        tmp.lights = [_light, _omni0, _omni1, _omni2];

For now you can change the ambient term of the materials that “receive” shadow.

Best regards.

I am not familiar with AGAL code, but my experiments found a crude temporary solution (while we are still hopefully waiting for BETA) for making shadows half transparent, without rising “ambient” parameter. So here is that crack for triple filtered shadowmap:
1. Open file away3d/materials/methods/TripleFilteredShadowMapMethod.as
2. Find line number 108

"add " + targetReg + ".w, " + _viewDirFragmentReg+".w, " + uvReg+".w n" + 

3. Comment it with //
