Shading the Building
Let's coninue applying the shading and baking method that we used in the previous task,
this ime for shading the building in our scene.
Engage Thrusters
1. Let's select the
building
object, and go straight to add two UV layers (
Object Data
tab in the Properies Editor). The irst UV layer must be named
diffBricks
and the
second
bake
; make sure to leave the first one selected.
2. Now switch to Edit Mode, then switch to the Face select mode and deselect any face
that could be selected now (
A
key).
3. Next, go to the
Material
tab in the Properies Editor, select the
bricks
material slot
from the materials list, and click on the
Select
buton just below it. That will leave
us with the faces on which this material is assigned selected.
4. Now we need to deselect the faces that are part of the sides, the back, and the top
of the building. The easy way to do this is to switch to Right View (
View → Right
),
iniiate the Border Select tool (
Select → Border Select
), and draw a rectangle
enclosing the faces that must be deselected, using the middle mouse buton. Then
go to the 3D View and use the Region to Loop tool (
Mesh → Edges → Region to
Loop
) to leave selected only the edges on the border of the whole region.
5. Now let's use the Mark Seam tool to tag the edges (
Mesh → Edges → Mark
Seam
).
6. The same series of steps (selecing a "side" of the building, then using the Region
to Loop command, and tagging the selected edges) must be applied to each side,
the top, and the rear parts of the building.
Once the seams for the faces of the building that use the bricks material are done,
let's create some more seams that we will need later.
7. Switch to the Face select mode (
Ctrl + Tab
, then press
3
) and deselect all of them
(
Select → Select/Deselect All
). Then go to the
Material
tab in the Properies
Editor, select the frames material, and click on the
Select
buton to select only the
faces that have this material assigned.
8. Right ater geing the faces selected, let's just go to the 3D View and use the Region
to Loop command (
Mesh → Edges → Region to Loop
) to get the borders of the
frames selected easily.
Finally, let's just tag the edges by going to
Mesh → Edges → Mark Seam
. Let's also
leave everything deselected for now.
