ABSTRACT
This article is intended more as a tutorial rather than technical or idea discussion. In this article I will explore a few texturing techniques to avoid the use of cluster materials.
INTRODUCTION
Fundamentally, putting materials on clusters seem to be the most logical approach to put different materials on a single mesh. For example, when I came [...]
