Introduction to Decals

Introduction to Decals

Decals are a powerful way of adding detailed textures to your game art with minimal impact on performance. This course will teach you everything you need to know about decals and will cover the complete development of 3 unique decals that can be used in a professional game environment.

Break Up Repetition

One powerful advantage of decals is their ability to very easily break up repeating, tileable assets and materials. Many Environment Artists use modular assets and materials in their work to cut down on unique resources to save performance and space. Decals enable artists to give the illusion of uniqueness to their worlds while operating within a performance-and-time budget.

Flexible Workflow

We will be using Substance Designer to create our decals, as the non-destructive workflow allows us to quickly develop decals and lay them out in an organized, easily accessible way. With a robust node-network, we’re able to quickly iterate and alter the decals to fit our needs better at any stage of the development cycle, allowing us to update each unique decal quickly and painlessly.
