Hey Wisdoms thanks for the reply.
I edited some blocks i am using for certain pieces of my ground in my editor. Right now in my layout they are a brighter "dirt" color with same wavy lines. I'd like to replace those with the edited ones. Now they are a darker red with a cracked sidewalk appearance.
I have some events that involve the "brighter dirt" colored ones. If i delete the 1st version i have to go back and redo all of those events. Is there a way i can replace the 1st version with the edited version w/o having to go back through all of the events involved.
