Hello guys, I'm trying to follow the tutorial here:Markers: Basic shapes

I managed to get it to work until I do: rosrun using_markers basic_shapes Then I get the following error:

> [ WARN] [1525948815.172388772]: Please create a subscriber to the marker

I open rviz, create a marker (as suggested on another discussion) but get an error message in rviz:

basic_shapes/0 frame [/my_frame]: Fixed Frame [map] does not exist

Screenshot

as well as this error in the terminal

[WARN] [1525951105.819784112]: MessageFilter [target=map ]: Dropped 100.00% of messages so far. Please turn the [ros.rviz.message_notifier] rosconsole logger to DEBUG for more information.

Thank you

You need to change the fixed frame box in RViz from "map" to "my_frame" (the frame in which your shape is defined). Or you need to define a TF between the "map" frame and your "my_frame" frame.

Thank you very much, so now my main goal was to open collada files in rviz and managed to do that, though, how can I load a dae file with textures, also can rviz show the dae file's local axis
