[TOOL] Kryon - 1-Click PBR Material Importer for ambientCG & Poly Haven

Development Pipeline & Plugins
1

Hey everyone,

I wanted to share a workflow tool I’ve been developing for UE5 called Kryon.

I use open-source libraries like ambientCG and Poly Haven constantly for scene blocking and Archviz. The materials are fantastic, but I was getting really burned out on the manual setup loop: downloading zip files, extracting them, dragging textures into the Content Browser, and manually routing the Base Color, Normal, and ORM (Occlusion/Roughness/Metallic) nodes every single time.

I missed the convenience of a true 1-click import workflow, so I decided to build a custom desktop app and UE5 plugin to bridge that gap for CC0 libraries.

What Kryon Does:

  • Native Desktop UI: Browse thousands of materials from ambientCG and Poly Haven directly in the app.

  • 1-Click Import to UE5: Click “Download,” and the custom C++ plugin handles the rest. It instantly imports the textures into your active UE5 project.

  • Auto-Routed Material Instances: It automatically generates a clean Master Material and applies your textures to a ready-to-use Material Instance. No node spaghetti required.

  • Extremely Lightweight: I built the desktop backend using Go, so it has a tiny footprint and won’t eat up your RAM while Unreal Engine is running.
