I would say at the outside 5%. (1-2 hours)Not really much to do but the edges...I have outlined the edges worked with a blue strip below....in one case it is just to chink out the morter in the entrance post to give it some bump.
In the first image I made a grass edge with roots showing and copied/scaled/distorted and cloned (cloning to remove paterning) it along the edge across the front but otherwise they are accomplished with a free hand mask. I just surround the edge (2nd image grass and concrete blend) and use filter/brushstroke/spatter...adjust the radios/intensity/smoothness...one pass only then a gausian blurr about .5 pixels. It seems to mix the colors cropped out by the mask nicely...experiment you will see.
The patch of grass in 26b (third) was easy enough to layer in...I had a seperate layer for the fence and so on..the trick is getting a shot (making a grass texture) at the right angle and distance from the ground....In the summer it is easiest to run outside and find a piece of subject grass...properly lit for your scene...with the shadow or grain burnt the same way....take the shot...run home....
One trick....if you are placing in a piece of grass that is obscured by a fence or vegetation...take a tip from the "green screen" technique...when you take your shot in Lumion, replace the grass with "green screen"(or any other single pixel color) ....that way you can "color select"with one click in PS all of the intricate pieces to create your clip mask.
