To create a tileable texture, use the Offset filter (Filter > Other > Offset) to place the border pixels at the center of the image and then use the Clone Stamp tool to blend the edges.
- Open the "trousers_occlusion.PSD" image you have created.
- Double click it and name it "Occlusion". Set the layer blending mode to Multiply.
- Copy the tileable tissue sample and paste it underneath the occlusion layer.
- Press Ctrl + T to rotate and scale the tissue in order to align it with one of the legs. Make sure that the weave and size of the cloth make sense regarding the direction of the leg.
- Erase the tissue texture at the fly area so that it doesn't overlap with the texture of the other leg.
- Repeat the procedure for the other leg and erase the overlapping texture.
Trousers texture 2
- Open the "trousers_cavity.PSD" image, copy it and paste it on top of all the existing layers (Fig.24).
- Change the blending mode to Overlay.
- You will notice that the stitches detail is fine, as well as the pockets. However the wrinkles are too strong. So, with a soft eraser brush, erase/tone down the stronger wrinkles.
To increase realism let's roughen the tissue at the front and back of the legs (Fig.25).
- Create a new layer below the "Occlusion" layer.
- Set the new layer to Screen mode.
- Pick a noisy brush and a very light blue color.
- Paint the front and back of the legs to lighten the tissue color.
I have searched online for images of jeans and pasted a couple of straps within the image. Later we will maps these to the trouser's straps.
- Save as "trousers_diffuse.PSD".
Boots texture 1
To create the boots texture I have first downloaded a leather sample from CGTextures.
- Open the "boots_cavity.PSD" image in Photoshop.
- Double click it and name it "Cavity". Set its blending mode to Overlay (Fig.26).
- Copy the leather sample and paste it below the cavity layer.
- Move the sample to cover the upper part of the boot.
I have adjusted the color of the leather to a darker and more saturated tone by using Brightness/Contrast and Hue/Saturation adjustment layers.
For the tip of the boot, I have used the same leather sample with a slight color adjustment to desaturate it (Fig.27). The decorations of the tip were erased to reveal the texture below.
