Software used: Photoshop.
Before you start, you will have to do some changes in the preferences, so open the preference dialogue, >edit>preferences>general. Under interpolation, change to nearest neighbor.
The rendered image is included in the zip.
First in ps, open the tga/jpg/bmp file containing the rendering of the house you are going to texture.
Open a new window to create textures for ceiling, walls, windows etc. like the ones below:
3. Decide which surface you want to begin with, I will begin with the top ceiling.
In my texture file, I will choose the top strip as top ceiling texture. Copy the entire top strip texture and pate it onto your render file as a new layer and give it an opacity of 50%.
4. Place the texture in one of the corners of the face you are going to texture, in our case the top ceiling.
5. Now to the somewhat tricky part:
While having the texture layer selected, press ctrl – T. This mode is called free transform.
You should now see a bounding box around the texture like in the screenshot above.
What we are going to do now is align the horizontal side of the bounding box with the top side of the surface we are texturing, like in the picture below. To do that, while in free transform mode and while pressing shift-ctrl, hold the middle anchorpoint on the right vertical side of the bounding box (encircled in red) and drag it down until the sides are aligned (encircled in blue).
NOTE It’s important that you don’t exit the free transform mode until after next step.
If you do, you will have to start over from step number 5.
Next, we need to align the vertical line of the bounding box with the left side of the rendered surface like in the screenshot below. While pressing shift-ctrl, hold the middle anchorpoint of the former horizontal side of the bounding box (encircled in red) and drag it to the left until the lines are aligned (encircled in blue).
6. Now we’re almost finished! Exit free transform mode by pressing enter. Press Go back to the layer window and hide the texture. Select the rendered house layer, in this case it’ll probably be the background layer. With the magic wand tool selected, see image below, with tolerance set to 5 and no anti-aliasing, select the top ceiling surface. Make sure that that is the only surface selected (if the surface is divided into smaller sections, i.e. blocked by a window, play around with the contiguous option and see if it helps, or add surfaces to the selection by selecting them with the magic wand tool while holding down ctrl).
Go back to the layer window, make the texture visible again, and select that layer. Inverse selection (press shift-ctrl-i) and press delete. Now the top ceiling should be textured like in the picture below, and the texture should be aligned perfectly!
Now all you have to do is start texturing the rest of the surfaces! Try adding different light to the textures by using the image>adjustments>levels tool or the image>adjustments>hue/saturation tool, to simulate from which direction the sunlight is hitting the building, use the rendered model as reference. Also try adding shadows for extra detail.
