Many models uses surroundings generated by OSM maps, but how we gonna do this ? Let’s find out

• Blender - https://www.blender.org/download/

• Blosm plugin - Plugin

Plugin installation

1. Download „Blosm“ Plugin from sharepoint

2. Open your Blender

3. At the top left settings panel go to Edit - Preferences

   Open

   

4. Head to Add-ons and click on Install… button

   Open

   

5. Locate downloaded Blosm zip file and click on Install Add-on
   
   

6. After installing Addon, Blender should automatically prompt you with new window. If not, locate search button in existing window and type osm and you should find blender osm addon installed.
   
   

7. If its not checked please enable it by clicking on the empty square before addon name and than click on little triangle next to it to show addon settings

8. Now in addon Preferences you should see Directory to store downloaded OpenStreetMap and terrain files
   
   

9. Click on folder icon next to it and choose directory you prefer. Usually is good to set same directory as client project you currently working on

OSM Website

1. Now we are gonna visit OSM map website

2. It should look like this

3. Locate search bar in top left corner and for the tutorial purposes you can type Skoda M18 (Škoda production buildings in Czech Republic)

4. Your window should look like this

5. In the center of the screen is our desired building but we wanna surroundings too, not just the main building

6. Zoom out and position view so the main building will be roughly in center

7. Now we gonna define desired area and export map so click on Export button in top right settings

8. Than we wanna click on manual area selection instead of automatic one

9. You should see new brightened square pop up on map

10. Now we can define desired area to be exported. See image bellow how to Scale and Transform area

• It works just like in Photoshop. With little squares you can resize desired area

• With this icon with many dots you can move desired area

11. Resize and Transform desired area but please keep main building roughly in center. Also you don’t need to cover huge area.

12. Somewhat this area is great

13. Now Export it

14. Download file should look similar to this (Without number 4)

Blender part

1. Press shortcut N to bring setting panel from right and between Tool, View and others locate osm part
   
   

2. Here in Settings panel change server to

3. Click on folder icon and locate generated map.osm

4. Now we need to uncheck things we don’t want to import

• Uncheck Import water objects

• Uncheck Import forests

• Uncheck Import other vegetation

5. Check Import railways

6. We can also tweak other settings but in default they are pretty set up.

7. Now click on Import button

8. After succesfully importing OSM maps you should see them in viewport, but as you can see we need to Rotate and Move them to match in real world

9. If your screen suddenly cut in half during zoom out. Don’t worry. You just need to change Clipping End value to 5000

10. During OSM transform you can see that your main building is imported too. Thanks to that you can easily match OSM position to match real world location

11. Please select OSM buildings in Edit mode delete main building part

12. Now on the right side panel you should see 2 types of objects

• Triangle one (Mesh)

• Line one (Curve)

13. Select all Curves, press F3 and search for convert to mesh

14. After converting please join all roads, footways, railways and similar paths into the one single object

15. After that you should have 2 objects - Buildings and Roads

16. Rename it if you like

17. Delete all OSM Materials and create one for roads and one for buildings

18. Now we optimize little bit. Select all buildings in Edit - Face mode and Merge close vertices by 0.1

19. Next thing to do is splitting buildings via separate by loose parts function

20. Last thing to do is cleanup. You can delete associated curves in way_profiles folder since we don’t need them anymore
