Transformers: Age of Extinction Explosion Scene

In the film, the visual effects team produced a large number of broken and explosive effects for the Hong Kong War, and extensively used image-based lighting technology to obtain more realistic lighting, which can be combined with on-site special effects when synthesized into the picture. In order to produce the effect of building crushing, the production staff need to study the structure and materials of each building, and understand whether the material is cement, metal or aluminum alloy, so as to make the crushing effect more real. First, various simulation algorithms are used to obtain the direction and scale of the crushing, distinguish materials such as metal, glass, and cement, and produce the effect of material distortion. Then, on this basis, more fine dust, debris, fireballs, etc. are added. In addition, the production team also added many aircraft to the battle scene, which naturally involves the simulation of the fire-breathing effect of the propeller.
