Gazebo ignores transparency tag when models are loaded from world or programatically from a plugin, but if the models are inserted from Insert menu, the models are transparent.

Used files:

• InsertBox.cc

#include "gazebo/physics/physics.hh"
#include "gazebo/common/common.hh"
#include "gazebo/gazebo.hh"

namespace gazebo
{
class InsertBox : public WorldPlugin
{
  public: void Load(physics::WorldPtr _parent, sdf::ElementPtr /*_sdf*/)
  {
    _parent->InsertModelFile("model://box");
  }
};
GZ_REGISTER_WORLD_PLUGIN(InsertBox)
}

• insert_box.world

<?xml version="1.0"?>
<sdf version="1.4">
  <world name="default">
    <include>
      <uri>model://ground_plane</uri>
    </include>

    <include>
      <uri>model://sun</uri>
    </include>
    
     <include>
      <uri>model://box</uri>
       <pose>0 0 2 0 0 0</pose>
    </include>

    <plugin name="InsertBox" filename="libInsertBox.so"/>
  </world>
</sdf>

• box.sdf

<?xml version="1.0"?>
<sdf version="1.4">
	
	 <model name="box">
      <pose>0 0 0.5 0 0 0</pose>
      <link name="link">
        <collision name="collision">
          <geometry>
            <box>
              <size>1 1 1</size>
            </box>
          </geometry>
        </collision> 

        <visual name="visual">
          <geometry>
            <box>
              <size>1 1 1</size>
            </box>
          </geometry>
	         <transparency>0.5</transparency>
        </visual>
      </link>

	</model>        
</sdf>

The one from the left is added via drag and drop, the two from the right are from the world file.
