Agog Labs joins Epic Games

We’re pleased to share that Agog Labs has become a part of Epic Games’ Unreal Engine team.

Awarded an Unreal Dev Grant in 2015, Agog Labs is known for SkookumScript, a powerful scripting solution and command console that is used to create AI, gameplay and high-level stage direction aspects of projects of all types across major platforms. Its live workflow includes robust yet simple and easy-to-learn features, native game concepts such as concurrency with minimal lines of code, and deep integration with Blueprints and C++. While active development of SkookumScript has ceased, it remains available as a community-supported plugin for Unreal Engine 4. 

For access to SkookumScript, visit http://skookumscript.com/download.  

Markus Breyer and Conan Reis

Conan Reis, CEO of Agog Labs said, “Here at Agog Labs our goal has always been to create authoring and development tools that allow people to focus on bringing their passionate imaginings to life. We melt our brains so you don’t have to. Epic has the same goals and spark of mad science, which makes it easy to align our paths. We’re honored to become part of the Epic family.”

Welcome to the team, Agog Labs.

Twinmotion breaks out of the box with a bridge to UE4

For more than a decade, Twinmotion has been offering an easy-to-learn and use solution for real-time architectural visualization. Two years ago, they switched their underlying engine to Unreal Engine. “When we decided to change our engine, we quickly saw that Unreal Engine was the most suitable solution on the market,” Twinmotion Product Manager Martin Krasemann tells us. 

“Unreal Engine is the most popular real-time engine in non-gaming industries, from car manufacturing to technology innovation in movies. It’s an amazing tool, capable of handling huge datasets and offering users unlimited possibilities, high-quality rendering, and—especially—a real-time environment,” he explains.

Lead Developer Manuel Veit agrees: “The Unreal Engine is a game changer,” he says. “With the engine, we have access to all the cutting-edge rendering technologies alongside a very solid development framework. Now we can bring Twinmotion to a higher level both in terms of performance and image quality.”

“Unreal also introduced us to a PBR (physically-based rendering) workflow which considerably enhanced the quality of our materials,” adds Lead Artist Fabrice Picou. “It’s the first time that I can work with a real-time gaming engine and produce photorealistic renders or real-time immersive VR experiences for architecture.”

Twinmotion leverages the power of Unreal Engine while adding a user-friendly UI, an integrated library containing thousands of assets, and specially designed architecture-related features—such as a weather system that lets you switch from a beautiful summer day to a winter snowstorm in two clicks, and the ability to easily add digital humans that will travel along specified paths.

A dynamic link with Revit and ARCHICAD drastically simplifies the architect’s workflow by retrieving all of the BIM information from the source software, and automatically replacing the basic billboards with Twinmotion 3D animated objects. Users can make changes to the model or materials in the source software, and see those changes immediately in Twinmotion.

The simplicity of the interface means that architects can get high-quality results very quickly, and with a low investment in learning. However, if they want to take their designs further into more complex simulations and visualizations, they were previously stuck.

At this year’s Autodesk University held in Las Vegas (November 19–21, 2018), Twinmotion demonstrated a technology preview of a bridge to UE4, an initiative they’d first announced at SIGGRAPH 2017. The bridge will enable architects to use Twinmotion as a quick prototyping tool, and then continue working on their designs in Unreal Engine or Unreal Studio, moving beyond the limits of Twinmotion. 

Unique in Twinmotion’s market space, this feature removes the frustrating “black-box” nature of competitive solutions, which blocks users from moving beyond the restricted range of features provided in the software. With the whole universe of possibilities of Unreal Engine to explore, Twinmotion customers can now truly differentiate their interactive or VR experience.

“Having Unreal running on the back is an amazing plus,” says Krasemann. “Users will have access to options that Twinmotion doesn’t have, such as baking lights or adding interactions, such as an opening door,” says Krasemann. “They can tell a different story inside Unreal.”

When asked about availability, Twinmotion told us that the feature is still under development and is planned to be released next summer. We look forward to it!

Want to see where your Twinmotion projects could end up after they cross the bridge?

Optim leverages the power of Datasmith to take the pain out of data-prep

As a company that has been using Unreal Engine to create AR, VR, and mobile experiences for a wide variety of clients for over four years, Theia Interactive knows a thing or two about data import and preparation.

“We’ve struggled through all the basic optimization challenges that we know our fellow enterprise customers share.” says CTO and Co-founder Stephen Phillips. “Bringing in huge datasets, getting rid of the junk, merging objects that don’t need to be exploded, instancing repeated meshes, creating LODs for high-poly assets, replacing materials, reorganizing a scene—the list goes on.”

With the advent of Unreal Studio and Datasmith in March 2018, the gap between CAD packages and Unreal Engine was effectively bridged, but there remains a significant amount of work to get architectural and engineering data to be as performant and clean as possible. Fortunately, much of that work is repeatable, lending itself to automation. 

“In the last year, Epic has really opened up the potential of the editor by making it 100% scriptable in Python,” say Phillips. “That means that people like us can start to write simple code to automate things like an import process, or common tasks like generating and deleting UVs.” 

The technical crew at Theia began compiling the company’s most common optimization workflows into repeatable scripts. But in order to make them more accessible to the artists and generalists that made up most of their team members, they decided to create a graphical interface that made it easy to assemble these automated tasks based on rules and parameters for any new project—with no coding required. 

“It very soon became clear that this was a product we could develop and license to other teams like ours” says Phillips. “And Optim was born. The number of hours saved has already stacked up internally, and we know it will be a game-changer for so many customers.” 

Optim uses Datasmith’s 20+ format support to get high-fidelity data out of those core applications. Epic has focused their technical skills on accurately bringing over metadata, converting materials to Unreal Engine, and dealing with a wide range of data-prep issues. Optim builds on that base to simplify the optimization process. 

With Optim, you can analyze your Datasmith and CAD files before you import them into Unreal Engine, saving you from having to load the full, heavy level and then hunt through bloated lists of content or complicated 3D scenes for items that require optimizations or edits. You can see the actor list, sort by triangle counts and other metadata, and set up optimization rules based on all these factors.

Some examples of things that you could automate with Optim are:

  • Skip the import of any meshes with names containing a certain string
  • Create LODs for any mesh larger than a given number of triangles
  • Instance any mesh with a particular name
  • Merge everything with a particular property under a single group
  • Replace all materials by name with existing materials from the Content Browser

“Optim demonstrates what anyone can do with the building blocks we’ve created with Datasmith and our work integrating Python in Unreal Engine,” says Ken Pimentel, Sr. Product Manager at Epic Games. “Theia has been quick to take advantage of these new capabilities in order to create highly simplified interfaces to manage a process. We have built this incredible platform and now we’re seeing the first fruit of how third-parties are taking advantage of it.”

Because Optim is developed in lock-step with Unreal Studio, it can immediately take advantage of new features as they are released. “When Epic solves hard problems like defeaturing and jacketing for complicated CAD models, or supporting new file formats, we are there to make a useful GUI and give you powerful controls for how to apply those optimizations and features to your whole project.” says Phillips. “We’re leveraging the power of Python and Unreal’s growing set of capabilities to automate existing workflows and save teams a lot of headaches in terms of time and skill wasted.” 

Theia intends to start selling Optim as a subscription in early 2019. But for those who can’t wait to get their hands on it, they’re currently accepting applications for alpha testers at theia.io/optim
