…and in Adobe Substance Painter 3D Painter 7.4.0, I’m using a Metal Roughness template, UDIM workflow and I’ve enabled the OpenColorIO Color management profile. For more details on the setup, check out this doc here:Įxtracting a 32bit Displacement Map from ZBrush In Maya 2022, I have a skull model that has topology and UVs and I’ve applied a 32bit displacement map extracted from ZBrush.

Although we’ll be using Substance, Maya/Arnold, you should be able to follow along in any PBR supported application that uses the Metal/Roughness shader model.įor more information on PBR-based shading and rendering, make sure to check out the Substance docs here and Physcially Based Shading at Disney:īefore we begin, let me give you a breakdown of what I have so far. We'll show you how to get started with SimReady USD assets, and present the tools and techniques required to develop and test these assets.For this walkthrough, we’ll be prepping our texture maps in Substance Painter and then setting up our shader in Maya/Arnold using the Metal/Roughness shader model. SimReady assets are more than just 3D objects-they encompass accurate physical properties, behavior, and connected data streams built on Universal Scene Description (USD). NVIDIA is introducing a new class of 3D assets called 'SimReady' assets-the building blocks of virtual worlds. Whether building digital twins or virtual worlds for training and testing autonomous vehicles or robots, 3D assets require many more technical properties, requiring a need to develop and adopt novel processes, techniques, and tools. Creating virtual worlds is hard, and today's existing universe of 3D assets is inadequate, representing just the visual representation of an object. The next wave of industries and AI requires us to build physically accurate virtual worlds indistinguishable from reality.
