 ====== From Blender to Unity : Earth V2.0 ======
@@ Ligne 13: / Ligne 19: @@
 In Blender, we start by generating two spheres: the first for the atmosphere and the second for the Earth.

+{{:brasil:courses:blender_unity:unity:earthv2modelisation.png?1024|}}
+Next, create the following shaders:
+{{ :brasil:courses:blender_unity:unity:earthshaderv2.png?1024 |}}
+For the earth, we'll use the following materials:
+  * {{ :brasil:courses:blender_unity:unity:textures-earth-nasa.zip |}}
+  * {{ :brasil:courses:blender_unity:unity:milkywayskybox.unitypackage |}}
+For the atmosphere, we'll also use the available image file in the archive:
+{{ :brasil:courses:blender_unity:unity:earthcloudsshaderv2.png?1024 |}}
+Before exporting in GLTF format just remove the "EEVEE" part of renderin. If not, the import of the object will not work :
+{{ :brasil:courses:blender_unity:unity:earthcloudsshaderexportv2.png?1024 |}}
+The result is as follows:
+{{:brasil:courses:blender_unity:unity:earthv2blender.png?1024|}}
+Atmospheric transparency:

+Next, we export the earth and the atmosphere separately in the glTF binary format:
+{{:brasil:courses:blender_unity:unity:exportglb.png?1024|}}
+To import these files directly into Unity, you need to add an import plugin. There are several available; we’ll install FastGLTF, which supports version 2.0 of the GLTF format.
+===== FastGLTF for importing GLTF files into Unity =====
+The project can be found at the following GitHub addresshttps://github.com/atteneder/glTFast
+For Unity, importing glTF files requires adding the glTFast package, which is now integrated into Unity:
+https://docs.unity3d.com/Packages/com.unity.cloud.gltfast@6.2/manual/installation.html
+===== Install the Unity glTFast package using the Unity Package Manager =====
+To install the Unity glTFast package, follow these steps:
+  - In your Unity project, go to **Windows > Package Manager**.
+  - On the status bar, select the Add **(+)** button.
+  - From the Add menu, select Add + package by name. The Name and Version fields appear.
+  - In the Name field, enter ''<color #ed1c24>com.unity.cloud.gltfast</color>''.
+  - Select **Add**.
+  -
+The Editor installs the latest available version of the package and any dependent packages.
+Once the plugin is installed, glTF files can be dragged and dropped into the project's “Assets” folder and will be immediately usable as GameObjects:

+===== Fly to the Moon =====
+Now it's your turn to create the moon in glTF format using Blender and import it into Unity:
