In this 3 part Maya workflow tutorial you will learn how to model, texture, and render a Katana, the legendary Samurai sword. For the modeling portion, we will use Maya’s basic polygon editing tools, while UVlayout will be used to create the UVs, and of course Photoshop to create the textures. We will also briefly cover Mental Ray for rendering the final image.
This tutorial is Day 3 in a series – Go to Day 1, or Day 2.
Step 1
The last time we prepared our model for texturing, we laid out the UVs and made UV snapshots. Now we are going to make the textures and bump maps in Photoshop. I’m going to use textures from www.cgtextures.com, where you can find a great choice of high quality textures completely free. Note: Redistributing textures from cgtextures is prohibited, so anywhere I use a texture from their site, I’m going to put the directory and keywords for searching so you can download it yourself. Luckily the finished textures along with a model are allowed for distribution. So let’s get started .[You must be registered and logged in to see this image.]
Step 2
Start Photoshop and open the outUV_blade.jpg (the UV snapshot we made earlier).[You must be registered and logged in to see this image.]
Step 3
Create a new layer (Layer>New>Layer), or you can use the keyboard shortcut (Shift+Ctrl+N), or click on the little icon in the layer palette .[You must be registered and logged in to see this image.]
Step 4
Fill the new layer with 50% gray.[You must be registered and logged in to see this image.]
Step 5
Go to (Filter>Noise>Add noise). For amount enter about 20%, for distribution choose Uniform, and check Monochromatic.[You must be registered and logged in to see this image.]
Step 6
Go to (Filter>Blur>Motion Blur). For angle enter 90 degrees, and for distance enter 90 pixels. With this we have our base for the metal .[You must be registered and logged in to see this image.]
Step 7
Double click on the background layer and then click OK in the new window. With this we have unlocked this layer.[You must be registered and logged in to see this image.]
Step 8
Place the unlocked layer on top of the metal base layer, and choose Linear Dodge for the blending mode.[You must be registered and logged in to see this image.]
Step 9
Now we are going to make the Hamon (the pattern on the edge of the blade). For that we are going to use the Dodge tool.[You must be registered and logged in to see this image.]
Step 10
For the brush shape choose a round brush with radius of about 60px, 90% hardness, and for the range choose Highlights.[You must be registered and logged in to see this image.]
Step 11
Add the pattern by just clicking to create the circle pattern, but only about 1/4 to 1/3 of the circle should fall on the edge. Make sure there is no overlapping on the edge itself. Repeat this step all the way down and on the other side too.[You must be registered and logged in to see this image.]
Step 12
Take the Healing Brush tool.[You must be registered and logged in to see this image.]
Step 13
Make the brush size 20px and the hardness 20%.[You must be registered and logged in to see this image.]
Step 14
Press the alt key, and click on the inside of the circles to take a sample. Soften the point where to circles touch.[You must be registered and logged in to see this image.]
Step 15
Take the Burn tool. The default settings are fine, but just choose a bigger brush (something around 150px).[You must be registered and logged in to see this image.]]
