the floor is weirdly grey and not 100% white. All face normals are facing inwards towards the content. Inverting just makes hidden objects below show up (backface culling on off didn’t help? Any ideas? or is there a specific verge 3D shadeless shader :P I also tried the shadeless shader which comes with -> “import images as planes” nada
Emittion is the only way to get shadeless material in Cycles, but you used it with Light Path that will not work for the shaders, only for world and you also fixed it with null shader that will also cause unexpected result. To get pure shadeless effet use only emittion with strength 1 or mix it using texture, but with another shader for example Diffuse shader or something. Cycles nodes support still in progress, most of the nodes are not supported yet.

I am not sure if I understand correctly but the node setup which you can see attached to my original message is the one that works, no texture needed. If your idea was to control the colors of a shadeless mat. then just plug the texture into the “Color” socket of the emission shader .
