I took some redcam footage of the sellwood bridge fromt he east side, and I removed most of the bridge so i could have it collapse, caused by an inial explosion at the concrete pilon. here are a couple of the tests.
First test where everything just falls all at once.
Here I've now got things timed out, but I need to remove the bounciness of the bridge and make it fall apart more.
Worked on the sim more and started working with Fume to see what I get. A good start, but much more work is needed.
