I want to make a display of enemy HP information through walls. And also a tag above the enemy, like in FarCry.

The dual camera method is not a good idea because it is VERY slow performance. (Was 900fps became 750fps on PC, and was 60 became 21fps on phone).

  • \$\begingroup\$ I'd recommend not using a worldspace canvas. Use an overlay canvas if what you want is an overlay, then position and scale the health bar elements in screen space to match the world positions of the entities they're annotating. \$\endgroup\$
