You can set the square color individually. The WallGeometry does not have a bottom so you don’t have to worry about that. You can change the height of the square corresponding to the height of the wall geometry.
You can add a label entity on top of the square geometry with a height slightly above it.
Several issues are summarized as follows:
1.version 1.71, Wall cannot close, v1.77 is ok.
2.if lable position is set dynamic value by SampledPositionProperty, lable always in the center of the polygon. I want the label on the polygon.
I confused why pixeloffset param is no use. cannot set relative position to polygon.
I use wall+polygon+label combine a box, barely achieved results,may be somebody can give me better solution. and hopfully, may some expert can give a demo of SampledProperty.addsamplespackedarray etc. sandbox lack of these demo.
if use Polygon extruded as Box, the StripeMaterial oritentation will wrong, whether horizontal or vertical, oritentation always horizontal.
