I extruded a shapefile based on altitude values in the shp.s attributes(setting a base height, and extrude height), then converted that layer to a multipatch with 3D Analyst. After symbolizing the multipatch(colors, transparency, and what have you) I used the Layer to KML tool to convert the multipatch to KML, in order to allow for viewing in Google Earth.
My resulting KML has black triangles all mixed throughout (as seen in the image below). Does anyone know the reasoning for this, and/or how to address this issue?
I have used Layer to COLLADA and it works fine (symbolizes properly with no black triangles) but I would prefer to use KML as the attributes seem to translate better from shp to KML.
Here is an image. The polygon on the left is the multipatch in ArcScene, the right is a KML in Google Earth.
I understand that the conversion from multipatch to KML draws the faces of the KML polygon as triangles, but why would they be discolored as such?
Any help is appreciated.
