HELP! MeshRay and Populate2D

hello there,

i need some help:

i created a grasshopper definition to illustrate the visual relations in a building. i used the mesh ray tool based on one point of view and generated a mesh that represents the field of view and its volume. until here everything is alright.

then i wanted the definition to generate the fields of view for more than one point at the same time. i replaced the single point of view by a 2d population of points and thought taht i would get the result for each point. but somehow it didn't work. comparing the result volumes i saw that only one of them has an acceptable size. and the visualization in rhino neither looks like an overlay of the different fields of view.

did grasshopper mix the data? what is the right way to generate seperately the results of the point population?

thanking you in anticipation!
