is an [Unreal Engine](https://www.unrealengine.com/en-US) plugin that reads [JSON](https://www.json.org/json-en.html) files from FModel [(UEParse)](https://github.com/FabianFG/CUE4Parse), and rebuilds assets like materials, data tables, physics assets, and more.\r\n\r\n✨ [Contributors](#contribute)\r\n\r\n### Example Use\r\n\r\n* Importing **materials**, data assets, and data tables — [see more](#asset-types)\r\n* Porting **physics assets** for skeletal meshes\r\n* Porting **sound effects** to Unreal Engine\r\n* Automating asset porting workflows\r\n\r\nThis project aims to streamline the porting and modding experience, making it easier to bring game assets into Unreal Engine.\r\n\r\n\u003ca name=\"licensing\"\u003e\u003c/a\u003e\r\n### Licensing\r\n\r\nJsonAsAsset is licensed under the MIT License. Read more in the [LICENSE](https://github.com/JsonAsAsset/JsonAsAsset/blob/main/LICENSE) file. The plugin also uses [Detex](https://github.com/hglm/detex) and [NVIDIA Texture Tools](https://docs.nvidia.com/texture-tools/index.html).\r\n\r\n-----------------\r\n\r\n### **Table of Contents**\r\n\r\n\u003e 1.

If the folder doesn't exist, create it in the root directory of your project.\r\n7. **Open Your Project**  \r\n   Launch your Unreal Engine project.\r\n\r\n\u003ca name=\"cloud\"\u003e\u003c/a\u003e\r\n### Set up the Cloud ✨\r\nMake sure Cloud is enabled in Plugin Settings, and set up a Cloud Server. [Click here to get to Cloud releases.](https://github.com/Tectors/Core/releases)\r\n\r\nOnce the Cloud is started, JsonAsAsset will fetch almost every referenced asset for you hands-free.\r\n\r\n\u003ca name=\"workflow\"\u003e\u003c/a\u003e\r\n## Workflow\r\n\r\n1. Find an asset in [FModel](https://fmodel.app), and save it by right-clicking and pressing `Save Properties`. Locate the file on your computer and copy the location.\r\n\r\n2. Press the [JsonAsAsset](https://github.com/JsonAsAsset/JsonAsAsset) button on your tool-bar, and a file import should pop up. \u003cimg align=\"right\" width=\"206\" height=\"96\" src=https://github.com/user-attachments/assets/6a9bf925-484b-4c23-b0ed-c59d58c5d07c\u003e\r\n\r\n3. Select the file and press Open.\r\n\r\n4. The asset will import, and bring you to the created asset in the content browser.\r\n\r\n\u003ca name=\"common-errors\"\u003e\u003c/a\u003e\r\n### Common Errors 🐛\r\n\u003cdetails\u003e\r\n  \u003csummary\u003eAssertion failed: TextureReferenceIndex != INDEX_NONE\u003c/summary\u003e\r\n\r\n------------\r\n  \r\nThis is a known issue in our code that we haven't fully resolved yet. While previous attempts to fix it have been unsuccessful, here's a partial solution to reduce its occurrence:\r\n\r\n- Re-launch your Unreal Engine project, go to JsonAsAsset's plugin settings and enable ***\"Disconnect Root\"***. Also enable ***\"Save Assets\"***.\r\n\u003c/details\u003e\r\n\r\n\u003ca name=\"contribute\"\u003e\u003c/a\u003e\r\n## ✨ Contributors\r\n\r\nThanks go to these wonderful people:\r\n\r\n\u003c!-- prettier-ignore-start --\u003e\r\n\u003c!-- markdownlint-disable --\u003e\r\n\u003ctable\u003e\r\n  \u003ctr\u003e\r\n    \u003ctd align=\"center\"\u003e\u003ca href=\"https://github.com/Tectors\"\u003e\u003cimg src=\"https://github.com/Tectors.png\" width=\"100px\"/\u003e\u003cbr/\u003e\u003csub\u003e\u003cb\u003eTector\u003c/b\u003e\u003c/sub\u003e\u003c/a\u003e\u003cbr/\u003eCreator\u003c/td\u003e\r\n    \u003ctd align=\"center\"\u003e\u003ca href=\"https://github.com/GMatrixGames\"\u003e\u003cimg src=\"https://github.com/GMatrixGames.png\" width=\"90px\"/\u003e\u003cbr/\u003e\u003csub\u003e\u003cb\u003eGMatrixGames\u003c/b\u003e\u003c/sub\u003e\u003c/a\u003e\u003cbr/\u003eCollaborator\u003c/td\u003e\r\n    \u003ctd align=\"center\"\u003e\u003ca href=\"https://github.com/zyloxmods\"\u003e\u003cimg src=\"https://github.com/zyloxmods.png\" width=\"80px\"/\u003e\u003cbr/\u003e\u003csub\u003e\u003cb\u003eZylox\u003c/b\u003e\u003c/sub\u003e\u003c/a\u003e\u003cbr/\u003eCasual Maintainer\u003c/td\u003e\r\n  \u003c/tr\u003e\r\n\u003c/table\u003e\r\n\r\n[![Buy Me a Coffee](https://img.shields.io/badge/Buy%20Me%20a%20Coffee-Ko--fi?color=ff0de7\u0026logo=ko-fi\u0026logoColor=white\u0026style=for-the-badge)](https://ko-fi.com/t4ctor)\r\n\r\n- Thanks to the people who contributed to [UEAssetToolkit](https://github.com/Buckminsterfullerene02/UEAssetToolkit-Fixes)!
