We received CAD files for the exterior and most of the interior, although all parts needed cleaning up and optimising. All the filters I had to model from scratch. All the modelling and scenes were built in Modo, using Vray references to import individual models into the main scene. Each reference had material tag and parts setup with animation frames for the different state of each model, such as the complete unit, cutaway reveal, filter and filter deconstruction. Then the main scene was used with render passes to create multiple colour variations and viewpoints without requiring updates to the source models. Rendering was with Vray.
