Maybe I'm doing it wrong but I can't get the scale of the carpet and grass materials right.
I usually work in centimeters on sketchup and it is impossible to get realistic scales for the height of the grass for example.
The scale is much too large.
The only solution is to work in millimeters which is very annoying.
The scale of the stranded materials should be adapted to the scale of the drawing.
Or at least, it should be possible to reduce the scale much more. Because even at the minimum the strands are huge if you work in CM.
