Hi,
I’m trying to recreate the Lidar scanner from The Voidness.
Here is a working example I found.
So far, I’ve tried:
- spawning decals on hit by line trace (50% fps drop)
- a niagara system (spawning a system on hit - giant fps drop)
- drawing the lidar dots on render targets
The third approach has been the most successful so far, no performance issues and a pleasing visual effect (the example I linked also uses render targets).
However, so far I’ve only managed to make a blueprint of a single plane with a render target. I can’t figure out a way to draw the lidar dot texture on objects that aren’t a simple plane.
Is there a way to add a render target to any object hit by line trace?
Thank you for your help
