STEP BY STEP ENSURE CLIENT BRAND CONSISTENCY IN IMAGES
01 SET UP THE 3D
The output of this render will be a colour-specific still file. In Cinema 4D, the hero objects, the cars, have all been set up with the same neutral black paint with a touch of diffuse weight, with a white colour to give a bit of a lift. The render has been set to output reflections, specular, mattes and ambient occlusion passes.
02 FILE SETUP IN PHOTOSHOP
Once the render is complete, the individual passes that have been outputted are gathered into Photoshop using File>load Files into Stack, which compiles the passes into a singlelayered Photoshop file. While multi-layer renders are available from most 3D engines, they can be problematic when saved, and if corrupted, all the render passes will be lost.
03 MAKE PHOTOSHOP CHANNELS WITH MATTE LAYERS
To create mattes for each car, ensure that the Channels palette is visible and press Create New Channel at the bottom. Select all of the pixels in a matte layer and copy and paste it into the new Channel in the palette. With the new Channel highlighted, press Load Channel as Selection at the bottom.
04 USE THE SELECTION TO MASK A GROUP
Press Create a New Group at the bottom of the Layers palette. Then, click Add Layer Mask to add the matte selection as a group mask. Drop in the Diffuse layer and then add a Solid Color from the Create New Fill button at the bottom of the Layers palette to add the brand colour. Repeat this process for every element that needs a specific colour.
