To start my project, I had several renders from Maya with the vehicle and the mannequins that all had different data on them such as the line work and normal maps.
From here I started to create groups for all of my different renders and groups to hold all of my different colors for individual pieces.
Then I imported my ID render and had it as my top layer. I would use my magic wand tool and turn down the tolerance to 1 and turn off contiguous. This allowed me to select individual pieces of the vehicle and mannequins so I could change the color individually. I did this for pieces such as the wheels and windows on the vehicle. I did a similar process for the pieces that have some gradient on it. Instead of having it be a solid color layer there would also be a gradient layer that is above it to create the gradient. This is an example of a few of my individual colors and gradients. I also added the Ambient Occlusion layer which had a big effect on all of my colors.
Determining the colors for this project was really hard because many of the colors would compete against one another or the color combination did not compliment each other the way I was looking for them to. A big part of getting the colors compliment one another was getting the background colors to pop out the colors used on the vehicle and mannequins. To start I put a black background and I thought about what needed to be on the outside of the vehicle to make it pop. I got my idea of paint splatters after looking at some photos of the KDA video and began making my paint splatters. Right around the edges of the vehicle I used the opacity of 100% but as I got further away I brought the opacity down to 30%. I chose to use the colors cyan, pink and orange. I then created fog using the Z depth render and made that into a light cyan color to create my background.
My last step was to create some small FX. I used this to create the small glow on the mannequin's helmet, lights on the vehicle, and beam coming from the satellite. I created a layer and put it on the color dodge mode. I then used an airbrush and put that too on the color dodge mode and selected a color. From here I did some painting in the areas that needed some glow.
