Blender 2.71 Shadow-Problem

Hey there,

got a short (noob)question: I did a simple 3d-camera-mapping. Everything worked fine so far. But now I´d like to add some more elements. Somehow there the floor with an Image as a texture (with an emission-node) doesn´t show any shadows. If I add a new plane, everything works fine, till I add the texture. Is that probably, because I unwrapped it from view?

#thanks a lot in advance!

Is it probably nessecary, to get the shadow over a seperate render layer and then to composite the whole picture? Does anyone has any idea?

thx again!

okay, guess I´ve got it. So it simply doesn´t work with the emission shader. I now try to fix this with render layers …
