 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. 
  
 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.

 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.
