Another one in the row. Reworked from scratch, using 12 flood fill and 12 turbulence filter primitives and what not. With the lack of editing options and performance issues it is easier starting a filter all over instead of tweaking an existing one. Once the chain is ready, you can make variants by changing some filter settings like flood colour (as in ithe first set) or turbulence base frequency (as in the second one), nothing bigger.
So here it is, a simple set of stone grunge filters. Shading, shape alterations, overlaying cracks, peeling paint, moss, embossing "could be added" to the filter, but rather have them separately.
