Dưới đây là một ví dụ về làm thế nào để sử dụng hình ảnh trong khung cảnh của bạn. Khi vẽ một tòa nhà với các cửa sổ lớn, tất cả chúng ta cần làm là thiết lập một bảng quảng cáo hình ảnh của một căn phòng, như thế này, đằng sau cửa sổ. Một người nào đó trên Flickr đã ảnh cho tôi. Thankyou! | Chapter 7 6. The contents of the layer are blurred in the direction you specified. 7. Select this layer in the layer pallet. Select the move tool and move it back approximately within the sketchy lines use the arrow keys . 8. Select Colours Brightness contrast then increase brightness and contrast a little until it looks like pencil shading. 9. Set the longer blend mode to Hard Light or Grain Extract as preferred. 10. Now mask out any areas where you don t want this shading to be like you did in the Dennis method. You can see me doing this here to take away the shading from the windows. What just happened You just took a shaded image from SketchUp added noise and blurred it to simulate pencil shading.

Add some grunge the Dirty Hands layer Just as the Dennis technique had a magic step so does Richard s. The following might not seem like much but it makes all the difference. Master this and no-one will be able to tell it s not genuinely hand drawn. 1. Import your Dirty Hands image in GIMP as a layer. 2. Move it to the top of the layer stack and select it. 3. Go to Filters Render Clouds Difference Clouds. 4. Use the default settings and click OK. 227 Non Photo Real with SketchUp 5. Go to Filters Noise RGB noise. 6. Leave settings as default and click OK. 7. Roughly mask or erase anywhere you don t want any smudging. You can see this in the following screenshot all the hatched areas are masked erased . 8. Set layer opacity to 15-20. Finishing touches 1. As with the Dennis technique add a Vignette layer to finish the composition. 2. Save a copy in GIMP .xcf format to allow you to edit it further some other time if desired. This format retains all the layers and masks. 3. Go to Image Flatten Image this will remove layers and masks . 4. Go to Filters Artistic Apply Canvas to get the paper affect. 5. .
