Creating a Stone fireplace

Hi Folks:

I am working on a project that has several fireplaces. In the past, I have just built a mesh object, and put a rock texture on it. The problem with this is that rocks on the corners and in other places dont match up correctly and I can never get things to look right.

What I would like to do is to actually build it rock by rock. The mortar is easy to do, but Im not sure how to create the rocks – I have messed with the rock generator in blender a bit, but I cant seem to get the correct shapes to the rocks – so im looking for the right way to make the rocks.

Below are a couple example fireplaces


Hi! Ihonestly don’t undestend the question. But did you do UV-mapping?

Interesting challenge:

Did you try this;

particularly the sixth one down.
