Fiddled with importing a tiff to use as something. Had to learn scale 1:1 for wood texture.
Grid type displacement.
Second terrain import from v9 (ter) Redoing old surface layers, adding crabgrass and FSS. breakup shader on FSS
Still experimenting with masking...
Grid tiff as terrain brick with grass pop peaking through (which I will try to figure out the mask for distribution density)
population with a tiff mask (tulips red 4 square) sort of English or pampered garden type
population on a SSS mask with PF distribution to look like rows ( red rows)
