I was watching a video (link to video) video and you could only see the shards where the places have hit the ground, but when I do cell fracture you can see the cracks before they've impacted with anything. I've checked on google and couldn't find anything. Also I want it so that the cracks only show up in the places that have been hit. For example, if a corner of a cube hit the ground then only the cracks in the corner will show and the rest of the cube will remain solid and intact. Watch the video I linked if you don't understand what I'm asking, it could help.
An example of my problem:
I did a cell fracture test with 0 margin but still got cracks where I don't want them (I know it's blurry, I just like my depth of field and motion blur) :
It's the same with a stationary cube with 0 margin which hasn't been hit. You can still see lines where the cracks are.
The examples in the video where it's show without any cracks where it hasn't been hit is in the first scene with the text and in the other seen with the horse. You can see that the top of the text has no lines or cracks until it hits the floor and it's the same with the horses body.
How would you recreate how the fracture in Phymec's video?
