1.2 Purpose

The primary goal of Voxelity Pro is to simplify the process of working with voxel data in Blender while preserving the fidelity of your original models. One of its standout features is the ability to convert meshes with textures into voxel-type meshes. These voxel meshes can be exported to various formats such as MagicaVoxel.vox Qubicle.qb Voxlap.vxl and many more voxel file formats. Importantly, this addon preserves color information during the conversion process, enabling seamless transitions between traditional mesh modeling and voxel-based workflows.

1.3 Functionality

Voxelity Pro boasts a range of powerful functionalities.

1.3.1 Functionalities
Feature Description
Mesh Voxelization Transform polygonal meshes into voxel-based representations with ease.
Texture Preservation Retain color information from textures during mesh-to-voxel conversion.
Bake Texture Bake any voxelized object with complex shaders into one Diffuse texture for easy export.
Import / Export Seamlessly import and export voxel file formats for compatibility with various voxel editors and game engines.
Efficient Workflow Intuitive tools and customizable settings streamline your voxel modeling workflow, enabling you to focus on your creative vision.
1.3.2 Limitations

Most file formats don't support exporting complex textures, let alone full-blown material definitions or other application-specific features. For more detailed information on this limitation, please refer to this link. Hence, we only support simple material definitions, either through the Image Texture node or basic color Diffuse definitions via the Principled BSDF node's Base Color socket.

No need to worry. Our integrated Bake Feature still enables you to use complex shaders to create model Diffuse colors. Just click Bake to consolidate shaders into a single Image Texture for easy export. Keep in mind, this process flattens your object by applying all modifiers, including the voxelization modifier, so ensure you back up your object beforehand. Baked images are not automatically saved, so remember to save them manually before closing to avoid losing them.

Currently, the addon is restricted to utilizing only one UV Map and/or Color Attribute per object. However, you still have the flexibility to employ multiple UV maps and Color Attributes and subsequently bake the outcome in order to successfully export the result.

Voxelity Pro works best with manifold meshes. For optimal voxelization results, ensure that objects possess a volume or thickness equal to or greater than the voxel size. For instance, a flat mesh lacking thickness will vanish during voxelization. To resolve this, simply extrude it to provide the necessary thickness or consider using a Solidify modifier.

Disclaimer and Usage Guidelines: Please note that while Voxelity Pro is designed to handle a wide range of meshes, there are practical limits to its performance based on your computer's specifications. High voxel counts and large meshes require substantial computational resources, including CPU, GPU, and RAM. Attempting to process extremely high voxel counts on large meshes may result in Blender crashing or becoming unresponsive, which is a common limitation due to the intensive nature of voxel processing. Performance can vary greatly depending on your hardware setup, and it is recommended to start with moderate voxel counts and gradually increase them while monitoring your system's resource usage.

Refund Policy: Refunds will not be issued for issues arising from exceeding the practical limits of voxel counts and mesh sizes due to hardware limitations. It is understood that pushing the limits of any software or addon can lead to performance issues. By purchasing and using this addon, you acknowledge and accept these limitations and agree to use the addon within sensible guidelines based on your system's capabilities. Common sense dictates that extreme usage beyond hardware capabilities can lead to crashes, and such cases are not eligible for refunds.
