To recap, I show the Tiles component again, with the new pattern so everything becomes more clear.<\/p>\n
First, we use a Threshold<\/strong> component, to put some stone texture on the result from the Tiles<\/strong> that are white.<\/p>\n The Treshold<\/strong> component setup like this:<\/p>\n As you can see, we map transparent color where the low part (anything else than white) is.<\/p>\n Now we drive the output from the Treshold<\/strong> component into a Get Alpha<\/strong> component, to get the Alpha channel, which we will use for the fun things we will do next.<\/p>\n Now, we drive the output from the Get Alpha<\/strong> component into an Offset<\/strong> component, and we set that up with 3<\/strong> as vertical and horizontal offset, and connect the Percentage<\/em> input to an Integer Slider.<\/p>\n Now we connect the output from the Offset component to a Blur component, doing a radius 5 gaussian blur.<\/p>\n Now, we use a Blend<\/strong>, (blend-1<\/em>) blend together the result from the Blur<\/strong> with the result from the Get Alpha<\/strong>, like this:<\/p>\n We now use another Blend <\/strong>(blend-2<\/em>), and blend together the output from the Threshold and the Mortar we made yesterday, like this:<\/p>\n The last operation we will do today, is to put back the alpha channel using the Set Alpha<\/strong> component. We set the Alpha on the result from b<\/em>lend-2<\/em>, using the result from blend-1<\/em> as the new Alpha channel.<\/p>\n![\"\"](\"http:\/\/4eyes.code66.se\/wp-content\/uploads\/2009\/12\/bp1-00.jpg\" "\\"bp1-00\\"")
