Yes… but not really. If you’re talking about doing this on a 1920x1080 viewport, then you’ll be doing 2073600 line traces, and storing 2073600 pairs of Vector2Ds and Vectors. It’s just too expensive for Blueprints. I think you would be best off doing it with C++, so then you could gradually write your results to a file instead of trying to store a ton of vectors in RAM and then dumping that to a file.
I tried to make it with Blueprints, but it just locks up the Editor and consumes tons of RAM.
Also, no matter how urgent your need may be, PLEASE DON’T DOUBLE-POST! It just fills this forum with spam, and makes people want to help you less
