How to achieve global illumination effects in Away3d 4.0 ?

I mean , i want to light every pixel of my scene in some special case, for example , if i want to light every face of a cube , i need to initial at least 6 lights ...this is really cost too much ......right ?

Also, at some time , i don’t need specular/gloss and diffuse effects ...may i turn off these default effects on the mesh surface? what i need is keep the illumination information from 2d texture to 3d surface,that’s enough , but how to achieve this light effects?

Some very basic forms of global illumination are provided through EnvMapDiffuseMethod and EnvMapAmbientMethod, which define diffuse and ambient lighting, respectively, using environment maps. These maps are typically special blurred versions of normal environment maps, created by tools such as HDRShop. Check out EnvMapDiffuseTest in the examples repo on Github.

To toggle lighting on a Mesh, simply keep two materials ready, and assign them whenever they’re needed. But it won’t necessarily be faster, you’ll need to verify that yourself.
