PolygonArray is always rendered as black color.

[pxlong]

Hi, thanks for sharing this great rviz plugin.

I use jsk_recognition_msgs::PolygonArray in Ubuntu 16.04 + ROS Kinetic.
The polygon array is always filled with black color in rviz when I disable "only border" and change "coloring" to Flat color, no matter what color I picked.

Sorry that I can not reproduce this problem
Can you try with this sample code to publish jsk_recognition_msgs::PolygonArray ?

rosrun jsk_rviz_plugins polygon_array_sample.py

and could visualize in rviz, I have tested in both deb (2.1.1) and latest source (2.1.3+)

Hi @k-okada, many thanks for the quick reply.

I recorded a video to show the problem. Please check: https://youtu.be/NufN7DZCzYU
It will not always be rendered in black, the color will change according to the viewpoint. At some viewpoints, the color seen by human's eye is black.

The polygon in my case is vertical to the ground (grid). Is this a reason to cause this issue?

OK, though I can not see your video as follows

I think I can understand your situation, how about #686 ? Will this solve your problem?
I'm not sure about your usecases, but in some situation, for example display float plane in 3D point cloud scene,current setting will help, so I added 'enable lighting' property
