Just gonna start by showing a screen since a picture says a thousands words
This is the good example here i have a wall selected so my blueprint turn in to this fading white greyish colors.
This is the bad example where i have the single slabs selected i cant see a thing!
So its pretty simple really can i have the faded color when slabs are selected.
You constantly select the slabs by accident and then you have to find a wall or some floors to get it less white.
and i think i done this 2000 times now its pretty annoying!
