JURI JABLOKOV EXPLAINS HOW TO ADD AND FIX TEXTURES IN PHOTOSHOP


HOW TO ADD A TEXTURE


01


OPEN THE 3D RENDER
First, open up your 3D render. Then “bring
a photograph into a new layer above the 3D layer
and merge it down to project using Ctrl-E key
combination. This projects the photo onto the 3D
model taking in account the maximum projection
angle that you have set in the 3D menu.”

03


ADD BACKGROUND AND TEXTURE
Jablokov’s workflow often involves putting a “gradient background into the Environment
menu’s background slot and set it to panorama mode so I would have some background to relate the
colours to.” This is a Photoshop render, but sometimes he exports back to Blender and renders from
there. Finally, add background texture.

02


USE LAYER MASKS
It won’t fit perfectly, so zoom in close
and see how the texture is applying. To fix any
problem areas, simply use Layer Masks. “Always
be sure of what layer you are painting on,” warns
Jablokov. “You cannot see the layer name if you
have only the 3D window open.

    http://www.turbosquid.com
    TurboSquid is probably the most famous collection of
    3D models on the internet, and they’re used in games,
    illustration, visual effects and much more. Many of the
    models are for sale, but there are lots of free treats to
    browse through too.

  2. TF3DM
    http://www.tf3dm.com
    A source of textures and tutorials as well as models,
    TF3DM is updated regularly, meaning that there’s
    always something new to have a look at. Again, it
    also has models that can be purchased.

  3. ARTIST3D.COM
    http://www.artist-3d.com
    It’s .obj and .3ds files that dominate this 3D model
    site, and it’s got plenty of categories, including people,
    vehicles and military items.

  4. CG TRADER
    http://www.cgtrader.com
    With categories like cars and food, there’s a good
    chance you can find what you need for free on this
    website. There’s also a forum, a blog and a gallery to
    keep you sticking around.


helps me to extract several map types out of the
textures I use for the diffuse colour. I can easily
manipulate them with Curves to get a reflectivity map,
or extract the very fine detail by applying a High Pass
filter in order to get a detailed bump map.” Using
Photoshop’s 3D tools Koch paints textures using and
says “I find the distortion tools great for adjusting
textures accurately to the model UVWS, creating all the
necessary texture channels (Diffuse, Specular, Bump,
etc.) and grouping them into folders gives me a
non-destructive workflow that allows me to make

quick and clean corrections. The save to layers script
is great to be able to export my layers without
collapsing them, giving me the option to come back
to Photoshop for fixes.”
But it isn’t just what Photoshop can do that makes
it vital to the 3D artist’s workflow. Koch says he uses
Photoshop “also as an excuse to be able to exit the
Operator mode and be able to see in a more critical
point of view, add comments, make some fast
retouches with Photoshop using other pictures,
allowing me to see my composition as a whole.”
