Arnold 7.5.2: 3D realism with photos and less noise

Autodesk has released Arnold 7.5.2, an update that promises to render 3D objects with greater realism. The main new feature is support for 3D Gaussian Splats, a technique that allows recreating real objects from photos or videos. Cartoon shading and image noise removal have also been improved. For creators, this means faster and cheaper visual effects.

How the new render engine works 🚀

The core of this version is the integration of 3D Gaussian Splats, which converts sets of images into renderable point clouds. This drastically reduces manual modeling time, as a real object can be digitized with just a sequence of photos or video. Additionally, the updated denoiser speeds up final render times, while the new non-photorealistic shading (NPR) offers more control over cartoon styles. Artists and studios can now produce complex assets with fewer work hours.

Now your grandma can also be a video game character 🎮

With this tool, there's no longer a need to spend hours sculpting a 3D character. Just record your cat running around or your uncle dancing at a wedding, and Arnold turns it into a renderable asset. Sure, the result might be a digital clone of your uncle with a mustache and all, but hey, that saves costs on hiring actors. The downside is that artists will now have to explain why the scene's background is their own kitchen.
