QFX Meshify lets you generate 3D assets directly in the editor.

The plugin offers batchable workflows that can process multiple prompts or images at once, transforming them into ready-to-use Unreal assets.

It automatically creates meshes, generates PBR textures, sets up materials, and imports everything into your project.

While these AI models are still in their early stages and don’t produce AAA quality meshes, the results are valuable for blocking, prototyping, and concept development. This makes it an ideal tool for rapid environment building and visualization. You can quickly turn reference images into fully textured 3D assets, saving hours of manual modeling and material setup.

This plugin runs fully local. No fees, no subscriptions, no credits.

PREREQUISITES

HARDWARE & SOFTWARE

The plugin is designed to run exclusively on Windows systems with NVIDIA graphics cards.
I would recommend to have at least a 16GB VRAM Nvidia card to run the plugin.
It has been tested with the following hardware:

💠 GeForce 3090Ti (24GB VRAM)
💠 GeForce 4080 Super (16GB VRAM)

Then, make sure the following software are installed on your system:

💠 Python 3.10.x – Download
💠 Git for Windows – Download
💠 CUDA ToolKit 12.8 – Download

When installing CUDA ToolKit, you only need the following features:

INSTALL TRELLIS/MATGEN LIBRARY

Ensure your hard drive has at least 35 GB of free space before continuing.

After installing the required components, proceed with the following steps:

1. Open the tool from the main menu (QFX > QFX Meshify)

2. Go to the tool settings

3. Be sure to select your Python 3.10 executable and choose a target folder to install the library

4. Finally, click on “Install Trellis/MatGen Library”

You should see a Command Prompt window appearing, like this one:

The installation process will download and install Trellis, MatGen, the related models from Github and Huggingface and the required python dependencies automatically.

This process can take ~30min, depending on your internet speed.

When the process is done, you should see this message, confirming the installation is completed:

You’re now ready to generate meshes in Unreal Engine!

DOCUMENTATION

WORKFLOWS

The plugin offers 2 workflows, Text2Mesh and Image2Mesh.

As the names suggest, Text2Mesh turns text prompts into 3D assets, and Image2Mesh does the same using images.

Text2Mesh

In this workflow, you can add multiple prompts and specify the number of iterations for each.

For example, here are four different prompts: we request 3 iterations for the Chair and 2 iterations for the Palm Tree.

Model Type
Selects model size (Base, Large, XL) based on your GPU’s VRAM capacity.

Image2Mesh

In this workflow, you can add multiple images using the Browse Folder or Browse Files buttons.
You can also rename each image individually, and these names will be used for the generated assets.

SAMPLING PARAMETERS

Seed
Determines the starting point for the random number generator used during mesh and texture generation. Using the same seed will produce identical results, while changing the seed creates variations. This is useful for recreating a specific output or exploring multiple design alternatives.

Decimate Ratio
Controls the level of mesh simplification after generation. A lower ratio preserves more detail but results in a higher polygon count, while a higher ratio reduces polygons, making the mesh lighter and faster to render but potentially less detailed.

Texture Size
Specifies the resolution of the generated textures (e.g., diffuse, normal, roughness maps). Higher values produce more detailed textures but require more memory and processing power. Lower values reduce file size and improve performance, but may result in less sharp textures.

Sparse Sampling Steps
Determines the number of steps taken during the sparse sampling phase of mesh generation. Higher values generally produce more detailed geometry but may increase computation time.

Sparse Sampling CFG
Controls the influence of the sparse sampling guidance during mesh generation. A higher value makes the algorithm adhere more closely to the intended design or input prompt, while lower values allow more variation.

Slat Sampling Steps
Specifies the number of steps during the slat sampling phase, which refines the mesh with additional structural details. Increasing this value can enhance fine features but may slow down processing.

Slat Sampling CFG
Sets the strength of guidance during slat sampling. Higher values result in the mesh more strictly following the input constraints, while lower values introduce more randomness and creative variation.

MESH PARAMETERS

Mesh Rotation
Adjusts the orientation of the mesh in the scene.

Mesh Scale
Changes the overall size of the mesh.

Smooth Normals Angle
Controls smoothing of surfaces; lower values keep edges sharp, higher values make them smoother.

IMPORT SETTINGS

Import Folder
Content Browser path where generated meshes will be imported in Unreal.

Asset Pipeline
Interchange pipeline used to import meshes and textures automatically.

Initializing AI Pipeline

This process can take ~60sec, depending on your hardware (GPU and PCIe bus speed).
It’s the time needed to upload the AI models on your GPU before starting the render batch.
