## What it is
SideFX's official Unreal Engine plugin that integrates Houdini's procedural workflow into the Unreal editor via Houdini Digital Assets (HDAs). Artists can adjust asset parameters interactively in the editor while Houdini cooks the results back into Unreal without baking.

## Use cases
- generate procedural levels and landscapes in Unreal with Houdini assets
- use Houdini Digital Assets directly inside the Unreal editor
- create procedural meshes, instancers, and materials for game worlds
- build bigger game worlds with procedural content creation
- integrate Houdini PDG and PCG workflows with Unreal Engine
- cook Houdini node networks and push results into Unreal without baking

## When to choose
- you use Unreal Engine 5 and want Houdini's procedural generation in your editor pipeline
- your team already authors Houdini Digital Assets and needs them usable by Unreal artists
- you need procedural landscapes, meshes, instancing, or world-building driven by Houdini

## When to avoid
- you need a runtime/in-game procedural solution - the plugin is editor-only, not runtime
- you don't have a Houdini install or license, since a full Houdini install is required to cook assets
- you need official Linux support - it is not officially supported there (source builds only)
- you use a game engine other than Unreal
