eruption
I have a 2D architectural rending of a building that I’m asked to make look like it’s erupting from the earth. I took still shots of the area where the building is to be built so I could composite the 2 together. I cut the building out & used a mask to make it look like it’s coming thru the grass. Unfortunately it still looks 2D. It’s needs to have the look like it’s pushing thru & grass is taring, dirt is flying. I’m wondering what other people might use to accomplish this? I tried trapcode particular but aren’t having luck with it. I don’t have a handle on the settings yet. Does anyone have any suggestions?
Thanks in advance-M -

If you want Photo-realistic, then your talking Big Bucks and a 3D programs, methinks.
You might be able to get away with a combo of CC Ball Action, Scatter, maybe Vector Blur and Y Scale on a masked Duplicate of the layer. It depends on how close you are also. A close-up on the grass will be tougher than a longer shot.
Dup the layer with the grass. With the Pen Tool make a mask shaped like a Horse shoe that will wrap around the extruding building.
Set Mask Shape keyframes from large horse shoe, at the end, to small horse shoe at the beginning of the eruption (double click the mask, you get a transform box).
Add CC Ball Action, Grid probably 0.
Keyframe Scatter from 0 to say 10 (your choice) quickly 3 frames or so, this is to be the grass flying, exploding up.Add Scatter. Amount to 5-10, to make the particles smaller. Try unchecking the “Randomize Every Frame”, whatever looks best.
Optional: You can even add Vector Blur, Type Direction Fading at 4 or so to make it stringy.
Anyway, once the lawn particle are up in the air, here comes the building thru the hole, the horseshoe shaped mask that is expanding from the Mask Shape keyframes.
To make the debris settle to the ground, animate the scale of the dupped layer. First move the anchor point of the dupped layer with the Pan Behind Tool to the bottom of the horse shoe, so the layer scale up and down from there. Then S reveals the scale and you want to disconnect the scales x and y by clicking on that little “Constrain Proportions” icon (looks like an infinity sign) and then animate the y Scale from 100 to zero (or leave a little if you want a little scattered about) with keyframes (the x scale stays at 100). This will give you a collapsing debris cloud.
You can play with colorama to bet a little dirt (brown) intermixed upon eruption.
That’s the quickie, better needs real 3D or the correct particles for Particular.
