🦟 Bug fix
Summary
When we updated the segmentation sensor (#329) to ogre2.2, it looks like inconsistencies were introduced in what pixel channels were considered RGB.
In
Ogre2SegmentationCamera::LabelMapFromColoredBuffer
, the notation is GBR: https://github.com/ignitionrobotics/ign-rendering/blob/7aade51f83171f2ada47089e6f8594fc3ccdddc5/ogre2/src/Ogre2SegmentationCamera.cc#L371-L373But, in the material switcher, RGB is used:

This PR updates the indexing in
Ogre2SegmentationCamera::LabelMapFromColoredBuffer
to RGB instead of GBR.Making this update fixes the label map data produced in gazebosim/gz-sensors#133. Before, the segmentation labels map was an image with all pixels set to the background label. Now, labels appear correctly:
