Concrete cracks & pitting
-
I did a search for this, however searching for sketchup + cracks finds a whole world of undesirable results.
I am in the process of just honing some skills and would prefer to keep all the modelling with-in sketchup where possible.
I have seen cracks added to structures through physical deformation via programs such as z-brush or adding deformation to image textures via photoshop.
I was just hoping there might be some ruby scripts and/or add-ons that are about to achive what I was after.
I have an office renovation project that has a concrete slab ceiling exposed and painted. It has lots of pitting, and many hairline cracks.
Any simple solutions, suggestions most appreciated?
(and even if not, I do enjoy the discussion)

I think the best way to achieve this effect would be to go the texture route vs. the geometry route.
There are some good concrete textures in the materials section of this website. Somebody linked a bunch of material resources in a thread.....they are all free....
Here's one: http://www.textureking.com/index.php/category/concrete

Is this being rendered? Is there any particular reason you want to do this w/ geometry vs. textures?
With pits and hairline cracks I can't see not using a texture. If it's being rendered a decent bump map will help you there. If you really want to get fancy or if you want to show some more depth from larger cracks and deformation then you're probably looking at more of a displacement map situation.
