Textures, shaders and postproduction
Proper textures and shaders will really bring your plants to life
Texporter
Texporter is a
plug-in that helps
you to create
basic templates
for textures.
Please remember
to keep the
resolution ratio
(width and
height) the same
as in the UVW
you have applied
to an object.
Once the
template is done,
save it and paint the
texture in your favourite
software. In the end, the
texture will perfectly fit
your object.
Utilise the Texporter
script to produce masks
for your textures

11 Paint the textures
In the early steps we applied UVW box mapping to the main
components, such as the flower and stalk. It’s a massive
help to have reference pictures taken from orthogonal views
for the elements you are about to texture. There is a great
plug-in called Texporter (www.cuneytozdas.com), which
may help when creating texture templates. Once the
template is ready, you can simply copy a part of the
reference picture and fit it to the comp. In some cases it’s
even better to paint the textures from scratch – as this will
give you more control over the size and placement k.
12 Create materials
After your diffuse textures are done, copy the layers and
desaturate them. Tweak the contrast and brightness to
prepare the Bump, Reflection and Translucent maps in
Photoshop. Once all the textures are set, choose the
VRayMtl and organise the channels as shown. To get more
control over the shaders’ behaviour, use the ColorCorrect
parameters with all created textures L.
Rendering additional
channels & postproduction
A standard Direct light with area shadows was used as
the main light source, clipped with VRaySky in the
environment and reflection override. In the
VRayPhysicalCamera, enable the depth-of-field
checkbox and set the correct focus distance. Add some
extra channels in the VRay: Frame buffer, as follows:
Alpha channel, Z-Depth, V-Ray raw reflection and the
Reflection filter.
In postproduction, control the reflection amount using
the ref. filter channel. Apply a Lens Blur filter in
Photoshop with a Z-Depth map. Finally, tweak the
setting to achieve an extra stylish bokeh effect.
Using additional passes, such as Alpha and Z-Depth channels,
hone the lighting and other effects in postproduction
k Use the orthogonal reference
photos for texture creation
L Control the shader’s
behaviour using the
ColorCorrect parameters

After several years of collaborating with
architectural studios, in 2008 I decided to
open MOTYW (MOTIVE). Working with
clients all over the world, I have become
very experienced in different types of
projects. I’m always looking for a
challenge in my work, to improve myself
and to evolve.
Housing in Bordeaux 3ds Max, V-Ray, Photoshop
(2010) An autumn dusk scene. I love to play with the
atmosphere of my scenes; nearly every time I am
surprised by the results.
Winter in the city 3ds Max, V-Ray, Photoshop
(2010) An urban environment in the winter. I spent
some time working on the street textures, painting a lot
of Displacement maps to achieve this effect.
