Simulating a building exploding from an image

I’m working on a film with my school’s film club and I’ve taken charge of all the visual effects. I’m pretty experienced with Blender and can do some advanced stuff but I don’t really know where to begin with this project.
I have a building that I have taken a photo of and I want to make it explode and look real.
I know that I can use the smoke simulator, game physics, and fragment shards plugin to do this but it seems a little overwhelming. I could use some advice.
I have already created a rough model of the exterior and reconstructed the camera position and angles. But what next?
I have several ideas but I don’t know which will work.
Ideas:

  1. Simulate the debris, fire and smoke and hope it masks the original image in the explosion and cut the scene before the dust and smoke disappears to reveal the original image.
  2. Create a full model of the destroyed building and while the smoke and fire covers the screen switch out the image with a destroyed building render
  3. Recreate the entire building as a model and don’t even use the original image in the final shot. Blow it up with fracture tools and smoke sim.

Which one sounds best? I have a short time to do this so I don’t want to invest a lot of time in one method to have the result not look good.

Im Not sure but you may try going into edit mode and unwrap from prospective and normalmap that way that may work but no promises

Actually that worked so great since the picture is high resolution! Now I have a perfectly textured model :D! Thanks!

I don’t know if bumps are allowed or not but I really need help. Is there any more info anyone needs?
