Blender releases their Oscar winning version tool (blender.org)
Blender 4.4 is all about stability. During the 2024–2025 northern hemisphere winter, Blender developers doubled down on quality and stability in a group effort called “Winter of Quality.”
Roblox releases code for Cube 3D Mesh Gen model (github.com/Roblox)
Foundation models trained on vast amounts of data have demonstrated remarkable reasoning and generation capabilities in the domains of text, images, audio and video. Our goal is to build such a foundation model for 3D intelligence, a model that can support developers in producing all aspects of a Roblox experience, from generating 3D objects and scenes to rigging characters for animation to producing programmatic scripts describing object behaviors.

In this paper, we present WonderHuman to reconstruct dynamic human avatars from a monocular video for high-fidelity novel view synthesis.
Building a Mesh Using Spherical Embedding (andrews.wiki)
When trying to build a 3D model of an object in the real world, the goal is most often to construct a connected mesh of triangles or quadrilaterals that represents that object's surface.
Hunyuan3D 2.0 – High-Resolution 3D Assets Generation (github.com/Tencent)
We present Hunyuan3D 2.0, an advanced large-scale 3D synthesis system for generating high-resolution textured 3D assets.
