tyFlow was initially positioned as a "complete overhaul" of Particle Flow, replacing the outdated native particle system in 3ds Max with a new-generation system. Over time, it has evolved into a multiphysics system capable of simulating granular fluids like sand, rigid bodies, soft bodies and fabrics, and even crowds of people. In recent updates, a terrain generation system has also been introduced. tyFlow can import and manipulate data in OpenVDB format, and volumes can interact with particle systems. It integrates directly with key production tools in 3ds Max. The core simulation runs on the CPU, while individual solvers operate on the GPU.

Despite a minor version number change, tyFlow 1.111 introduces a significant new feature: the tyDiffusion module. Described as an "advanced implementation" of Stable Diffusion, tyDiffusion enables the use of a generative AI model in 3ds Max through the ComfyUI graphical interface. The module takes viewport information such as color and depth and feeds it into the AI engine, allowing the 3ds Max scene to direct the AI-generated output.
In the video above, you can see tyDiffusion being used to generate images corresponding to a low-resolution 3D character pose and animations based on simple guiding geometry. The developer describes it as a "full scene render, not just a random image generator."

In addition, you can project the AI-generated image onto a 3D model for a more traditional AI-based texturing process. The implementation supports "all checkpoints and Stable Diffusion 1.5 and LoRAs" for Stable Diffusion XL, as well as ControlNet and AnimateDiff. tyDiffusion is available in both the free and professional versions of tyFlow, with users of the free version benefiting from GPU acceleration support, unlike the native tyFlow toolset. Among other changes in tyFlow 1.111 are improvements in exporting particle caches and Alembic point clouds, as well as "Unreal Engine-compatible resolution resampling" during terrain export.

tyFlow 1.111 is compatible with 3ds Max 2018 and above. Some of its features with GPU acceleration do not rely on hardware, while others are CUDA-based and require a compatible NVIDIA GPU. The free edition, tyFlow Free, includes all modeling tools and can be used for commercial purposes, but lacks CPU multithreading, GPU acceleration, and cache exporting. The cost of tyFlow Pro is $495 for a perpetual node-locked license and $645 for a floating license.
