 ==== Texture Atlas ====
-A texture atlas is a custom image combining many different textures all in one image. It has the huge advantage of asking the CPU/GPU to load only one image and pick all the textures for different objects from parts of that image. The inconvenience is that each texture will have a lower pixel resolution (being part of a greater image)
+A texture atlas is a custom image combining many different textures all in one image.
+It has the great advantage of asking the CPU/GPU to load only one image and objects are unwrapped to pick their textures from different pars of that image.
+The drawbacks are that you need equivalent maps for different values of roughness, metalness, normals and AO and each texture will have a lower pixel resolution (being part of a greater image)
+This technique works very well to add a stunning level of detail to the shading of Low Poly environments instead of flat colors

+==== Texture Slots ====
+Texture slots enable you to give different textures to different parts of a mesh.
+Select the parts of the mesh and select another slot material and click assign.

 ==== Seamless textures ====
-Using seamless textures is useful as the texture will repeat itself when scaled without it being too noticeable at a glance. However, if you scale too much, a pattern will become visible as the texture repeats itself.
+Seamless textures repeat themselves when scaled down without it being too noticeable at first glance. A pattern does become visible if you scale too much as the texture repeats itself.
 There are two ways to scale :
-In the node editor, on the **mapping** node :
-{{3d:mapping-node.png?200}}
-In the UV editor, by scaling the unwrap. This second option is preferable if you are going to export your scene to a game engine as the UV unwrap (and it's scale) will be exported with it.

 A handy feature of seamless textures is that they will continue applying if you modify your geometry. One good way to do this is with an edge slide (Shortcut : ''G'' + ''G''). If you want to edge slide beyond the existing geometry you need to remove clamping (Shortcut : ''C'' while edge-sliding).

+===== Eevee Bloom =====
+Open the **Compositing** workspace.
+Tick the **Use Nodes** option.
+Add a **Viewer** node and render the scene. Connect the render to the **Viewer** node.
+Optionally add a **Image Editor** viewport and view the **Viewer node** for a clearer view of post-process.
+Use **''SHIFT'' + ''RIGHT CLICK''** over the noodle to insert a **Reroute** and after the **Render Layers** node add a **Glare** node.
+Switch to **Fog Glow** and adjust settings.
+{{:3d:eevee-bloom.png?direct&500|}}
+When in Layout view, Rendered preview, the Viewport Shading dropdown menu enables to activate the Compositor when in Camera view, Always or never (default).
+This is useful to get any post-process effect to display in real-time in the Layout view.
