Quixel provides one of the world's largest libraries of professionally curated 2D and 3D assets, including surfaces, vegetation, and decals. These assets are captured from real-world objects using advanced photogrammetry, then refined and optimized for use in various creative projects, particularly in game development and film production. The platform aims to empower creators by offering instant access to photorealistic content, allowing them to focus on their artistic vision. The product suite includes Megascans, a comprehensive library of photorealistic 2D and 3D assets, and Megaplants, which offers procedurally customizable, Nanite-compatible vegetation specifically designed for Unreal Engine 5.7's Procedural Vegetation Editor. While Megascans are available for purchase, Megaplants are free to use. Quixel assets are primarily accessed through Fab.com or the Fab in Epic Games Launcher, which is gradually replacing the legacy Quixel Bridge tool, offering streamlined access and integration with digital content creation (DCC) tools and engines.

Mixamo is a 3D character animation platform that provides a large collection of high-quality 3D character models and motion captures. It's designed to simplify the animation process for game developers, animators, and designers, allowing them to quickly bring characters to life without extensive animation expertise. Users can upload their own 3D characters, which Mixamo can automatically rig, and then apply a wide range of pre-made animations from its extensive library. The platform is ideal for individuals and teams working on games, virtual reality experiences, architectural visualizations, and other projects requiring animated 3D characters. Its key benefits include accelerating production workflows, reducing the need for manual animation, and offering a diverse selection of character and motion assets. Mixamo integrates seamlessly with various 3D software and game engines, making it a valuable tool for rapid prototyping and final asset creation.

Turn photos, drawings, or prompts into print-ready and game-ready 3D models

HI3D.cc turns a photo, a drawing or a text prompt into a 3D model in the browser: a full-colour model with 4K geometry and PBR maps, a print mesh exported as binary STL and 3MF in millimetres with a print check (watertight, wall thickness, smallest printable height), or a game-ready mesh of about 15,000 triangles with an optional 24-bone auto-rig. Downloads in GLB, FBX, OBJ, USDZ, STL and 3MF; every model opens in AR on iPhone and Android.

AI sprite animation that starts as video, so capes and hair actually move.

I built MotifDeck because sprite animation lives or dies on the small stuff: a cape that lags a step behind, hair that trails a turn. So it animates your approved character as continuous video first, then extracts and cleans up the frames. You see every source frame, start from a suggested selection and keep your own cut, up to 16 frames on Free, Starter and Creator or 64 on Pro and Studio. Then set the order and timing and export PNG frames, sprite sheets, GIF or ZIP.

Generate 3D models, animation, materials and sound for game production

StudioTwin is an AI toolkit for game and virtual production asset generation. You or your AI agent can create 3D models, character animation, PBR materials, HDRI environments and sound effects, each using curated models for the task. In Unreal Engine, results land in the project as native assets, and the StudioTwin Blender addon imports them into Blender. Toolkits, models and workflows are added.
