Some folks think installing rocks is a big deal. Not really; quite simple. Put your 'rock' up against a section of your diorama or layout. Trace around the 'rock' with a knife and place your 'rock'.
Then using that WS foam putty I showed earlier fill in behind the 'rock', total time for these four rocks, about 10minutes.
Ed, Thank you. The ship is a $105 version of the Black Pearl. 1/96. Naturally mine does not look like the Black Pearl. I've made enough modifications that fit the period, 1680, that it is no BP anymore. Great model and should be within most folks skill level. Moderate. I didn't finish it off with all the rigging because this ship, like my trains, is merely a photo prop. Jim
Time found to get the first coat of WS Earth Blend ground cover. No mystery here. Squirt on the glue avoiding the rocks as best you can and shake on the ground cover. Doesn't need to be pretty as there will be at least three more ground covers to be added. J
