How to create the 'ruined' or 'destroyed' effect on architecture

Sharky85

so im looking for a quick way to model out ruined or destroyed pieces of architecture, for example say i want to make a before and after version of the roman colosseum, ive already modeled out the before structure, is there any way to quickly snip out a large section, leaving an area that appears noisy? Ive tried using boolean but it doesnt seem to give me the right effect. Any ideas or suggestions?

It max, one easy way is to create a plane with a good number of subdivisions, put a noise modifier and set it to 70,70,70, and check the fractal box. Then use procutter or booleans to create a rough looking slice through the model. You can use the noise modifier on spheres and other shapes and manually deform them before using procutter as well.

Depending on if It's a high poly or not

without any actual experience in that, i would say that the look of the respective part of the building after the destruction relies heavily on the way that it is build. broken beams of wood look much different from destroyed brickwalls (the bricks itself should remain intact), which in turn looks very different from a broken concrete wall. i would think that you have to find a way to have you model look realistic for each of the constructional elements separately.
therefore, i dont think that there really is one quick way to model that. the only thing you can do to reduce the time needed would be not to model too much detail for each element and to only model the basic forms and characteristics...
