Documented Workflows
Mesh To Texture
Workflow documentation in the Waterfront Courtyard project from modular mesh kit development and organization in Maya to coordinated texture sets in Substance Painter for use in Unreal Engine 4. Using the modular mesh kit and their corresponding textures, the aerial and land drone configurations were assembled in UE4 blueprints and linked to material instances that read the textures and allow for vertex painting.
Texture Mask & Color Variation
Documentation in the Waterfront Courtyard project of defining a mask layer and texture for meshes to receive color variation in Unreal Engine via an exposed color parameter that can be defined per instance. Notes the mask definition in Substance Painter, material master and instance structure, and application in UE4 level and blueprint instances.
