Voxel Plugin

Voxel Plugin is voxel technology for Unreal Engine, with version 2 focused on creating and generating interactive terrain. Worlds can be edited at runtime, and those edits are described as reversible and non-destructive. Terrain is built with stamps that produce 2D height data or 3D volume data, with procedural results staying consistent when the same seeds are used. Voxel Graphs provide node-based control over generation, but are not part of the Free plan. The plugin targets Nanite as its main rendering pipeline and supports tessellation and displacement there. Unreal Engine's PCG framework can query voxel terrain and metadata, and PCG graphs can call Voxel Graphs. Foliage generation and interaction use PCG rather than direct plugin handling. Voxel Plugin 2 targets Unreal Engine 5.6 and 5.7 and is actively being developed; its documentation warns it may be buggy. It does not currently support cubic terrain or static, pre-baked world generation. The Free plan allows commercial use. Pro costs $$349 once and is not for project budgets over $200k.

Voxel Plugin provides procedural terrain tools for Unreal Engine, with runtime editing and PCG integration. Check the limits on terrain types and baked generation, and note that version 2 is still in development.

It suits Unreal Engine developers creating procedural, interactive terrain who want runtime edits and seed-based consistency. The Free plan may suit users who do not need Voxel Graphs or access to Voxel Plugin 2 previews.

Voxel Plugin is a procedural terrain toolkit for Unreal Engine projects that need interactive worlds. It is best suited to developers building terrain with runtime changes and PCG workflows. Its strongest case is reversible editing paired with node-based generation in Pro; cubic terrain and baked worlds are outside its current scope.

Overview

Voxel Plugin 2 focuses on creating and generating interactive terrain. Worlds are authored with stamps that produce either 2D height data or 3D volume data, and generation is deterministic when the same seeds are used. That makes it a fit for projects that need repeatable procedural terrain, rather than a general-purpose solution for every kind of game map.

Worlds can also be changed at runtime, with changes described as reversible and non-destructive. That is useful when terrain needs to respond to play without treating edits as permanent. The trade-off is that Voxel Plugin 2 does not support cubic terrain or static, pre-baked world generation.

Key features

Procedural authoring and rendering

Stamps generate 2D heightfields or 3D volume data, with seed control for reproducible output. Voxel Graphs add node-based control over world generation, but they are excluded from the Free plan, making Pro the relevant choice for graph-driven authoring.

Nanite is the main rendering pipeline, with support for tessellation and displacement in that pipeline. This gives the plugin a defined rendering focus; projects that depend on cubic terrain or baked world generation should look elsewhere.

Runtime editing and PCG

Unreal Engine's PCG framework can query voxel terrain and its metadata, and PCG graphs can call Voxel Graphs. This connects terrain generation to broader procedural workflows. Voxel Plugin does not itself generate or handle foliage interaction, so foliage workflows need to use PCG.

Version 2 is actively in development and may be buggy. Its documented release targets Unreal Engine 5.6 and 5.7, and it can be downloaded through the Voxel Plugin Installer or GitHub. That makes it a more cautious fit for production-critical work than for teams able to accommodate a developing tool.

Pricing

Voxel Plugin Free: free. It includes commercial use and full source code access, but excludes Voxel Graphs and access to Voxel Plugin 2 previews. It suits developers evaluating the core workflow or working without graph-based authoring.

Voxel Plugin Pro (for budgets <$200k): $349, paid once. It adds Voxel Graphs, Discord support, team sharing, and access to Voxel Plugin 2 previews, while retaining commercial use and full source code access. It is intended for projects with budgets below $200k and is not for projects over that threshold.

Custom License: custom pricing. It includes access to Voxel Plugin 2, a support contract, full source, unlimited budget, and Slack access. It suits projects that exceed Pro's budget limit or need the listed contract and Slack support.

The Free plan's main saving is also its key compromise: it lacks Voxel Graphs and Voxel Plugin 2 previews. Pro is a one-time payment, while the Free plan costs nothing; no renewal term is stated for either plan.

Platforms

Voxel Plugin is listed for Android, macOS, and Windows. Its documented engine targets are Unreal Engine 5.6 and 5.7, so the engine version is a practical compatibility consideration for developers.

Who it's for

Choose Voxel Plugin if you are building interactive Unreal Engine terrain, value reversible runtime changes, or want voxel data to work with PCG. Pro is the stronger fit when node-based Voxel Graph authoring or access to version 2 previews matters.

It is a poor match for projects that require cubic terrain, static or pre-baked worlds, or direct foliage generation and interaction from the plugin. Teams that cannot tolerate bugs in a tool under active development should also be cautious about adopting version 2.

Pros and cons

• Pros: Reversible, non-destructive runtime changes suit worlds that must respond to play.
• Pros: Deterministic seeds and both height and volume generation support repeatable 2D and 3D terrain workflows.
• Pros: PCG can query terrain and metadata, while PCG graphs can call Voxel Graphs.
• Pros: The Free plan permits commercial use and provides full source access.
• Cons: Free omits Voxel Graphs and access to Voxel Plugin 2 previews, limiting graph-based work on the no-cost plan.
• Cons: No cubic terrain or static and pre-baked world generation rules out those workflows.
• Cons: Foliage generation and interaction depend on PCG rather than direct plugin support.
• Cons: Version 2 is still in development and may be buggy.

Alternatives

• TerraWorld 2023 is a paid alternative at $99, paid once, with no free plan or trial; consider it if you want to compare another paid terrain tool.
• World Machine has a free plan and an Indie plan at $119 a month; consider it if you want a freemium alternative with a paid Indie tier.
• Gaea offers a free Community Edition for non-commercial use, capped at 1,024 × 1,024 single-build resolution, plus an Indie plan at $99 a month. Consider it if those limits and terms suit your terrain work.
• L3DT has a free Standard Edition for heightfield and texture maps up to 2049 × 2049 pixels, plus a Professional trial. Consider it if a capped heightfield workflow is sufficient.
• 3D Dungeon Generator is a free web creator for dungeon sizes from 16×16 presets to 60×60 custom dimensions, with GLB export. Pick it for dungeon layouts and GLB output rather than Unreal voxel terrain.
• Heightmap Level Generator is a free option available on the web, Windows, and self-hosted, with no install or account. Consider it for a lightweight heightmap-level workflow.
• Infinity Generation has a Free Alpha plan with full software use during the Alpha period and a 1% royalty on annual gross revenue above $100,000. Consider it if those terms fit your project.
• MapMagic 2 offers a free core asset with map generators; its Biomes and Functions add-on costs $45, paid once, requires an existing MapMagic 2 installation, and includes one seat. Consider it if that add-on structure fits your needs.

Verdict

Voxel Plugin is a strong choice for Unreal Engine developers who need procedural, interactive terrain and want runtime changes to remain reversible. Its PCG integration and Pro Voxel Graphs give it a clear role in graph-based terrain workflows. Look elsewhere if your project needs cubic or pre-baked worlds, direct foliage handling, or a mature version 2 tool without the risk of active development.
