Hi there,
I got a bunch of simple text components (about 15) which should always face the player (the white font elements):
So I made a little blueprint script ‘camera facer’. It works like this:
It simply calculates a rotator depending on the actual camera position.
The problem: It’s incredibly slow. My framerate takes a very critical hit as soon the font elements are visible. It runs fine, if I set enable to false which causes the text elements to draw, but prevent them from autorotating.
Even if I include it directly in the parent blueprint (not using a blueprint script component) it’s not difference. I also tried to use a timer and to run it only 10 times a second, but even then I have no chance to hold my target framerate anymore.
Engine version: 4.7.6 (binary)
UPDATE: It seems to have something to do with the rotation of the text objects. If I just rotate every text objects at a random vector, it adds about 3 ms of draw calls:
Why does this perform so bad? Is there any method to speed this up?
Thank you,
