# Editing glTF assets with DCC Tools (import/export) degrades content.
## Prerequisites
1. Download the amazon-sumerian-hosts project.
2. Download & Install Blender v2.83.10 (to conform with the original glTF assets).
```json
"asset": {
"generator": "Khronos glTF Blender I/O v1.2.75",
"version": "2.0"
},
```
## Steps to Reproduce:
1. Imported [luke.gltf](https://github.com/aws-samples/amazon-sumerian-hosts/blob/mainline2.0/packages/amazon-sumerian-hosts-three/examples/assets/glTF/characters/adult_male/luke/luke.gltf) into Blender with these settings and saved as Luke.blend.

2. Exported Luke.blend to luke.gltf with these settings

3. Build, run
## Observe differences between the original (right) and the imported/exported (left) glTF assets.
### Differences
- Jay Leno's chin.
- More detailed clothing.
- Shinier skin.

> This repository contains 3D character and animation assets (glTF format) tailored to work well with the Hosts API. You can use them as-is, modify them in digital content creation software such as [Blender](https://www.blender.org/) or use them as a guide to develop your own 3D assets.
**[Readme claim 2](https://github.com/aws-samples/amazon-sumerian-hosts/tree/mainline2.0/packages/amazon-sumerian-hosts-three#step-7-define-asset-variables)**
> Note: If you import the glTF assets into a DCC tool like [Blender](https://www.blender.org/)
It does not look like it without some major degradation!
## Question
**How do I import/export glTF assets with Blender or any other DCC tools to be able to edit them and preserve the look & feel, please?**
