I need to load ArUco marker inside gazebo environment. I created a Cuboid with sketchup, and embedded the ArUco Marker image to one face of the cuboid (shown below) then I export the dae file for the model.

When I load the above marker in Gazebo I face two issues

• Shadow is weird (I then turn off the
• scene>shadow) Flickering

Did anyone else face this problem?

Sketchup:

Marker loaded in Gazebo (weird shadow + flicker)

After turning off shadow

How do I remove this flicker ?
here is a similar collada file and that flickers too when I load in Gazebo.

EDIT

I tried to load the collada file in MeshLab. It flickers there as well. Seems like the file itself has some issue.
