How an AI-assisted workflow fast-tracks material creation

, octubre 12, 2020

Powered by NVIDIA GPUs, Unity ArtEngine’s AI has simplified workflow, and helped create vMaterials – a free library of over 2,000 high-quality real-world materials. 

Creating realistic materials can be a time-consuming process. Even when working from high-quality references, it can take days of work to achieve impressive results. So when a team at NVIDIA was building up their vMaterials library, comprising more than 2,000 real-world materials, they looked to an AI-based solution in Unity ArtEngine. Powered by NVIDIA GPUs, ArtEngine became an indispensable tool in the pipeline that raised the quality of the produced textures while speeding up turnaround times for texture creation. 

Real-world textures, ready to use

NVIDIA’s vMaterials library includes essential textures for visualization and can be used with renderers that support Material Definition Language. To build this free catalog with a robust offering of ready-to-use materials, the team at NVIDIA used both photogrammetry and photometric techniques. 

While these workflows ensure hyperrealistic results, they also come with a host of challenges. Removing seams or artifacts when tiling materials for large surfaces is a time-consuming process, and working with wrinkled fabrics or shadowy images can add days of tedious work to a project. While the final results are good, the workflow was not always efficient and the output was limited. 

ArtEngine’s AI-assisted artistry offered a solution by using an example-based workflow to automate some parts of the material-building process. Automatically removing seams, artifacts, and shadows allowed for more efficient material creation – even if the source material wasn’t top quality. “If you take a picture and it’s not what you want,” says Maik Rohland, texture artist for vMaterials, “the tools can get it where it needs to be.” While some materials had previously taken days to create, the AI-based solution brought that down to a few hours

Automation, artist-friendly

While automating parts of the workflow gave the NVIDIA team more time for creativity, the tools also gave the artists flexibility while allowing them to retain complete control over the final output. Material Mutation made it easy to create variations quickly, turning one material into many and bringing more realistic variety to objects in a scene. ArtEngine’s intuitive user interface also eliminated any guesswork The team ramped up on the software easily and made it an essential part of their workflow. 

From the beginning, the goal for the vMaterials library was to showcase materials exactly as they appear in the real world. Using NVIDIA GPUs, ArtEngine’s AI allowed the team to develop a pipeline for creating ultrarealistic real-world materials efficiently and increase their output. It has become an integral part of their process, allowing artists to spend less time on tedious tasks and more time on creativity.

Accelerate your productivity

ArtEngine has tools to help almost any artist increase their productivity and improve their workflow. If you’re interested in learning more, why not try a 30-day free trial or explore the vMaterials library.

So, this awesome free library from nvidia is actually incompatible with Unity?
Why are you even posting this here? O_o

If you write an article about how cool and hyperrealstic these materials are you should tell us how we can use them in Unity. If we can’t you scored a nice own goal…

This is a stupid question (I hope) given that this is the Unity Blog, but does the vMaterials library work in Unity? It’s not in the Supported Application list?

Good question. Looks like Unity is not on list of supported applications :/

Adobe (Allegorithmic) – Substance Designer
Chaos Group – vRay for 3ds Max/Maya
Dassault Systemes – Solidworks Visualize
DAZ 3D – DAZ Studio
Epic – Unreal Studio
NVIDIA – Iray for 3ds Max/Rhino/Maya
Siemens – NX

Do you mean we need to render them out with ArtEngine first then import into Unity or we can directly use them in the Engine?

You should really mention that trying Art Engine means that users could be charged a minimum of 1140USD if they fail to terminate their license before the trial period expires.

It’s disappointing that Unity is missing a huge opportunity here to really elevate the capability of small development teams by preventing amateurs from learning how to use these, supposedly, powerful tools.

That’s not a very clear answer.

So to be able to use MDL materials in Unity, we need to rent ArtEngine?

Does ArtEngine load MDL materials?

You realise how funny it is, that you made an article, about nVidia making some materials with your tech, and those materials can be used freely with Unreal, but you have to jump through many hoops to use them in Unity.

Here are our thoughts about ArtEngine: integrate it inside Unity and make it free for Plus and Pro Unity licenses.

Yeah, I’ve downloaded vMaterials (a lot of MDL files) and I can’t view them anyhow.
Looks like they are not yet supported for Game Development in Unity, which is really lame. =D
But there’s vRay for 3ds Max/Maya which supports them, so I guess Artists know how to get these materials into Unity.
