Part 3: Materials & Textures
Step-12 Now we are going
to apply materials and textures to the vase and the floor. We
will start with floor first. Select the floor in object-mode.
Press [F5] to bring up
Shading & Materials features in the
buttons-window.
Press 'Add-new' button to assign a material to the floor. As
soon as you assign a new material the 'Add new' button gives way
to 'material name entry-box' click it and type 'Floor-mat' for
easier identification.
Step-13 After assigning a
material you can now add textures to it. For floor we are going
to add a wood image texture. Press
[F6] , the
Texture-buttons window
opens. In 'Texture' tab click 'Add new' to add a texture
channel. Immediately a 'Texture-type' drop down list appears
from it select 'Image'. Again a new tab called 'Image' tab
appears next, click the 'Load Image' button and browse to the
texture wood-tile.jpg, select it and press
[Enter]. In Xrepeat: and
Yrepeat: increase both values to 4.
Step-14 After adding the
wood image texture, we will now modify the Shading parameters of
the floor material. Press [F5]
and got to 'Mirror Transp' Tab next to Shaders and press 'Ray
mirror' and increase the 'RayMir' slider to .20. And finally
Depth 3 (under Ray Mirror button), thats all is needed for the
wooden floor material.
Step-15 Following the
procedure in step-11 add a material for the vase. Then add three
image textures namely vase-tex.jpg, vase-tex-spec.jpg and
vase-deco.jpg in three different channels. You can rename the
texture channels by entering text in the Add new box which by
default will show Tex(#). Rename all of them suitably.
Step-16 We had added
three image textures for vase and now we will modify the shading
property of the vase material. Press
[F5], in 'Shaders' tab
change 'Ref' (diffusion property) to .400, next change Spec
(specularity) to 1.700 and Hard to 400 also Depth=3. 'Lambert'
and 'CookTorr' are the algorithms user to calculate the
diffusion and specular property of the textures.
Step-17 Now we need to
give proper mapping values to the three texture channels. In the
Texture tab(far right) you can see the three texture channels
being visible. The 'Map-input' and 'Map to' tab will change the
value of only the channel which is currently pressed(vase-tex).
So to modify the properties of other channel you have to first
select them. Go to 'Map input' Tab select Tube mapping for all
three channels.
Step-18 In Tab 'Map to'
the first texture channel need not be changed. For sec channel
disable 'Col' and enable 'Spec' and 'Emit' buttons. Also change
the Var slider to .500.
Step-19 For the third and
the last channel change the texture blending mode to 'Multiply'
from the default 'Mix' and 'Col' value to .500. Try out the
render now to see the materials you applied. Also save your work
now.
