2. HOW I MADE MY UV MAPS -

3. STEP 1 – CREATE A SURFACE
To begin making a UV map
and to texture and object, I
selected the polygons I
wanted to texture and
pressed Q. This opened the
surface creator and I was
able to name this surface
“Chandelier_Rifle_Barrel”.
4. STEP 2 – MAKE BASIC UV MAP
After the surface had been created, I then navigated to the maps tab and
clicked ‘New UV Map’. I then named the UV map
‘Chandelier_Rifle_Barrel_UV’ and changed the Map Type to Atlas. I then
pressed Create and my UV map will have been created.
5. STEP 3 - PHOTOSHOP
After creation on the UV map, I could use the snip tool to select the UV and
copy and paste in into Photoshop. Whilst in Photoshop, I will be adding
textures to the UV. The yellow objects on the UV represent the various
different polygons I had selected when creating the UV, so what ever
texture goes on top of them will be put on the actual object later. I then
saved the new textured UV in a specific folder as a .JPEG.
6. STEP 4 – SURFACE EDITOR
Back in modeller, I pressed F5 to get to the surface editor. Here, I clicked
the T represented in the image below to open the texture editor. Here, I
changed the Projection to UV, the UV map to
‘Chandelier_Rifle_Barrel_UV’ and the Image to the image I just created
in Photoshop.

7. STEP 5 – CHECK + REPEAT
After the texture editor has been set, the object looked like the image on the
left. I then repeated this process to get the final product which can be
seen on the right.
For the rest of my models, I used the exact same process in order to create
and develop UV maps and textures.
9. STEP 1 - EXPORT
To export an object in modeller, I went to File > Export >
OBJ. You can also export the file to FBX, but I prefer OBJ
for more complex objects as I have found that a lot of the
time when you import them into unity, the textures
become solid colours and this can be quite hard to fix.
Once the OBJ option is selected, I saved the file into a
new folder.
10. STEP 2 - IMPORTING
To import an object into unity, I went to Assets > Import New
Asset. This opened the file viewer and I then would select
the .OBJ file I saved after the previous slide and the
engine would begin the import. After the .OBJ had been
imported, I then had to import all of the UV textures into
the same folder.
11. STEP 3 – APPLICATION
To apply the textures onto an object, I found out that I first
must double click the object so that one whole part of the
object is selected, but not all of it. This part would
correspond to all the polygons used in the UV. I would
then have to drag and drop the correct UV to the place
marked on the image below, and this would upload it to
the image.
