blender-2.78-ad40000-win64

renderlayer.blend
If I render the scene in Blender Render with 2 separate layers, result is

If I switch to Cycles with Film set totransparent, result is rendered normally

As if material and light info is not rendered correctly when merging 2 layers in Blender Render.

Blender Internal and Cycles indeed behave differently here. I made Cycles behave different because I think it makes more sense this way, if you want consistent behavior between lights and meshes emitting or bouncing light.

Changing Blender Internal would break backwards compatibility, and many existing .blend files would stop working. It is possible to do such changes for example in Blender 2.8x, but what will happen with Blender Internal in that version is still to be decided. In any case it's not strictly a bug, but a design that could be improved or modified.

Yes, please, could you modify/improve this render layers feature for BR in future releases?

Could you explain how render layers work differently in BR versus Cycles?
How come lights and materials on render layer 1 do not affect render layer 2 (Blender Internal)?

Please keep/improve Blender Render (Internal) in 2.8x for it's unique raster engine.
