Was playing around with negative values on a multi fractals buoyancy and noticed it is a good base for canyons, so I slapped in a strata and erosion, and than played with some separate displacement on lateral based on a inverted deposition map.
Not happy with the populations but I'm limited to 3, and not sure what to do with the last. Want to refine the density locations, namely keeping them near the "greenzone". Quick models from sketchfab. Tall palm and cycas revoluta.
Number 2 I have added little better veggie colour map under the object pops, but messed up my Cycas colours. Fixed that and doing a higher GI render overnight.
