I said the pillars looked a little too new, and today we’re gonna do something about that. We’re gonna create a Bump map for this.<\/p>\n

We start FilterForge<\/a>, and create a new filter.<\/p>\n

\"\"<\/a><\/p>\n

First, we add a Stones<\/strong> component to the workbench. We set the scale a little smaller than de default, but that is about it. Now we add a Tone Curve<\/strong> component, and connect the output from the Stones to the Source<\/em> input. We now create an Impulse<\/strong> curve component, and adjust it a little to the right of the scale, give it a little more width and plateau. This will as you can see help us filter out the lines between the stones.<\/p>\n

\"\"<\/a><\/p>\n

We now play a little with noises, mostly Perlins<\/strong>, but add a Chaff<\/strong> here to be a little daring. What we do is to control the output by chaining a few filters controlling the roughness of each other. The resulting noise is set to have a light grey background and a white noise. This is really not needed but a fun way to show how many different ways you can connect things in FilterForge.<\/p>\n

\"\"<\/a><\/p>\n

Now we use a Threshold<\/strong> component to grab the lines as cracks and add the roughy noise as surface. We then add a Noise Distortion<\/strong> to make the cracks look even more random.<\/p>\n

And here is the result, rendered with a smaller size to get more cracks into one image.<\/p>\n

\"\"<\/a><\/p>\n

And here is the filter itself.<\/p>\n

cracked.ffxml.zip<\/a><\/p>\n

So, how did it look when we added this as a bumpmap in Cheetah3D<\/a> and rendered a pillar again?<\/p>\n

I think it looks great, now we got a little age to it.<\/p>\n

\"\"<\/a><\/p>\n

I hope you had fun and that you learned one or two things, I did. But wait, the end caps still looks way to new. I guess we need to fix them too, tomorrow.<\/p>\n","protected":false},"excerpt":{"rendered":"
