 Cut out windows and doors using the knife (''K'') tool in the base object. Then select the edges, duplicate and move them outwards, scale them down a bit, separate to make a new object, in that new object in edit mode extrude outwards and then add a solidify modifier. Take care that your normals are facing the right way. If you have mirrors not applied be sure to activate clipping so that the points on the mirror axes don't separate from each others when scaling down. Cut out windows and doors using the knife (''K'') tool in the base object.

-It's handy to start with a boxed shape then inset faces and extrude them and scale them down along the normal to get quick good looking volumes. 
  
-Trees and landscapes can be sculpted with a finer mesh and then decimated using a modifier to bring them back down to Low Poly.

-Good practice : Duplicate elements using ''Shift + D'' and then detach using ''P''. (e.g. to detach a roof off a roughly boxed building) 
-Duplicate face loops and extrude along the normals towards the outside (e.g. to create pipe joints) 
  
 Careful : Rotations in edit mode do not apply a transformation relative to global axes. It's better to rotate in object mode so the local axes are preserved. Careful : Rotations in edit mode do not apply a transformation relative to global axes.

-N-gones are OK to model with as long as they are kept on a same surface. It is safer though to tidy things up with the knife tool to create quads and triangles. Blender converts everything to triangles to render anyways so tidying things up brings you closer to what Blender is actually seeing in your mesh. 
- 
-If your mesh is chiseled looking and shaded differently because the quads and triangles are not on the same plane you can flatten things out by selecting all the concerned faces and scaling them to 0 along the proper axis. 
  
 Careful when using mirror modifiers, if you move in object mode it moves both sides in the same direction along the given axis because it moves the object center around which the mirror is calculated. If you move in edit mode it moves the selection relative to the given axis effectively copying the move on the mirrored side. Careful when using mirror modifiers, if you move in object mode it moves both sides in the same direction along the given axis because it moves the object center around which the mirror is calculated.

 For pavings its better to work with a plane and solidify modifier than with meshes as you don't have to worry about thickness ; don't forget to apply scales as the thickness will be affected by the changes in scale as you duplicate and randomize these objects. For pavings its better to work with a plane and solidify modifier than with meshes as you don't have to worry about thickness ; don't forget to apply scales as the thickness will be affected by the changes in scale as you duplicate and randomize these objects.
- 
-Grass and plants can be made easily with a few loop cuts along a plane and scaling ends down and rotating a bit the edges to get some variation. 
- 
-You can precisely reset the origin point to a vertex by selecting the vertex and setting the 3D cursor to the selection ''SHIFT + S'' and then setting the origin to the 3D cursor. 
  
 Poke faces is useful for creating a collection of triangles on a big N-gone like circle shape. Poke faces is useful for creating a collection of triangles on a big N-gone like circle shape.
  
 Applying modifiers is really up to you and depends on if you need to edit the full mesh (in which case apply) to break symmetry  Applying modifiers is really up to you and depends on if you need to edit the full mesh (in which case apply) to break symmetry 
- 
-Texture slots enable you to give different textures to different parts of a mesh. To do so, select the parts of the mesh and select another slot material and click assign. 
- 
-Eevee vs Cycles : Cycles is a Ray based renderer while Eevvee is a screen based renderer. Eevee tries to keep things as simple as possible and kind of flat while cycles is trying to be as realistic as possible. Eevee is a real-time renderer while cycles is more resource intensive and requires many samples to produce good results. 
-Surfaces that are emissive will have a much better render in Cycles than in Eevee. 
  
 When beveling you can press ''CTRL + B'' and then ''V'' to bevel a vertex and create a triangle face where the vertex was. Direct shortcut is ''CTRL + SHIFT + V''. When beveling vertices, use ''J'' to join opposite vertices that were created to re-triangulate the faces and correct the geometry. When beveling you can press ''CTRL + B'' and then ''V'' to bevel a vertex and create a triangle face where the vertex was.

 Linking on the other hand imports a collection as a single object. Note that the origin point for that object will be the world origin from the original file, so if the collections are not centered on that world origin it will be offset when you link it. Also note that the link is not dynamic so any change made to the object in the original file will not update in the other project until the first one is linked again. Linking on the other hand imports a collection as a single object.
