Exporting Several Meshes to Ecotect using Geco

Hi,

Ive been playing around with grasshopper  (Im really loving it)and ive tried to make a reactive facade. Ive gone through several tutorials and sort of used bits from each. 

Ive created a set of window panes which rotate following a reactor point which ive set on a circle. However when i load the meshes into ecotect, i can only see one mesh in ecotect, and not the whole model. Does it analyse the whole model, or just each window pane? Also when I import the colours from ecotect back into grasshopper all the window panes have the same colour. 

Im quite sure there's something Ive missed out. i cant seem to figure out what though.

Any help with this would be really appreciated.

Best,

Omar
