Any muddy terrain for Cyclorama?

RenderPretender

Hi...

I have had some good use out of Cyclorama, and have seen and bought a number of terrain options for it, such as beach, woodland, etc.. There are also some nice free materials out there. But I was wondering if anyone knows where one might find some muddy terrain, the sort you might see in an area where offroad vehicles have been mudding. I have tried to create my own tracks with one product here for that, but it was very cumbersome to use, and the results were less than I'd hoped for.

Thank you for any tips!
