Ir1 and ir2 images are in the same frame

[akkoyunlu]

Altough Infra1 and Infra2 are assigned to own frames in d435i_urdf.xacro, Infra1 and Infra2 on Gazebo are in same frame. But, Infra1 and Infra2 are in own frames o Rviz. I think Infra1 and Infa2 frames lump on gazebo. I put

"
true

"
this code block to prevent lumping problem, but same problem occured again. How can I solve this problem ?

I put this ,

	<disableFixedJointLumping>true</disableFixedJointLumping>
