We have fairly large scenes generated from data files. In the scene there are multiple static objects with labels on them (TextMesh). Currently we’re doing a lookat operation to make them face the camera and a distance operation to make them scale with the camera distance. The camera is able to move with complete freedom.
I’m looking for ideas on how to improve this as the distance operation is killing our FPS and the rotation is too. We’d like the text to always be the same size and always be facing the camera. It seems like an overlay UI would be good for this, but I don’t know how we would fix the UI in world space but always have the labels in the proper position and face the camera. A bit of a conundrum.
