🦟 Bug fix
Fixes gazebosim/gz-sim#496
Summary
Fixes issue with ign-gazebo's TransformControl tool being occluded by models.
The ogre2 transparency blend mode setting was being override when copying a material due to the order of the calls.
->
SetTransparency-> sets blend mode->
SetAlphaFromTexture- > overrides the blend mode set in the previous call if arg isfalseThe PR reverses the order to make sure we keep the blend mode if visual is semi-transparent
Also made sure that if
SetAlphaFromTexture(false)is called any time afterwards, we don't change the existing blend mode.Checklist
