Saving to collada (*.dae) from blender won't effect color to the rviz and gazebo

Hi, i have a problem, i save *.dae format from blender, but it won’t effect anything (the color) to the rviz and gazebo. anyone have solution?

Have a look at the urdf file, it might be set the material there and it might be overriding the textures in the dae.
