To test this PR, you can select the engine and try to start the simulation with the worlds available.
If you selected Ogre engine, the PRB textures will not be loaded because Ogre is not able to load PBR textures.
If you selected Ogre2 engine, the world should open and render everything without any difference.
Tests:
[ ] Load Husky with the Fuel Depot world (ogre and ogre2). The world will not load the textures when using ogre engine.
[ ] Load Tugbot Warehouse world scene (ogre and ogre2). This world is supposed to load the textures using ogre, but the light effects are not ok and some april tags will not load.
[ ] Change to the Local tab and try to create a new world (+ button) with ogre and ogre2. Add models and save the world.
