The Luma team replaced a number of backgrounds incorporated into the the helicarrier, building our own facade, adding CG extensions and matte paintings over the base model. Lighting was a key concern. The actors in the plates were often brightly lit from the sun, so when we put the dark helicarrier behind them, they would glow. No bueno. There was a real craft to getting it right. Luma artists were meticulous in everything from adding replacements, to actually going in and painting down the highlights.
We got in on the gore too. Luma added a digital blade to Deadpool’s sword, which he plunges into an opponents stomach, then jumping on the weapon to slice him in half. This was a hybrid shot where the team blended in a digi-double for the wound area and added the guts and blood. The team took this approach for all but the most extreme action shots.
We used practical gore elements, creating special rigs- a meat balloon, of sorts, that explodes with corn syrup and fragments of meat, and a pressurized side can filled with fake blood. Blood simulations were generated using Houdini. We had done so much gore work over the years, that we pulled from our libraries of intestines, pancreas’ and anything else a that splurges from a body when being attacked by an antihero.
