Ground Topology interpretation
theluthier I think at least the main problem with the ground plane is that currently it is being based on an assumption that the ground in the artwork is flat, but (to my eyes at least) the ground in the artwork is composed more of small hills/hillocks/mounds and dips and so on.
Case in point: when I had a closer look at the cart in the artwork, my understanding was that the cart is parked on top of a small hill such that while someone might think that the wheels and bars are both lying perfectly on the ground, they are in fact at different heights. duerer
And about the front bushes, after lowering the ground plane I, personally, might have moved them closer towards the camera and scaled them on the Z-axis to better match the artwork. So that you could then have a reference point in the 3D scene to know how far to also bring the curvature of the river bank towards the camera as well and additionally re-sculpt the current flow of the river.
Of course this is all dependent on whether or not we continue trying to Xerox the concept or use it as a jumping off point instead.
To my eye in the concept art, the foundation of the water wheel house is built into the ground rather than resting on it (as it was in this Casual Stream). Like the foundations of a castle surrounded by a moat.
Below is how I see/interpret the representation of the water wheel in the concept art. hharbinger_ua
Hopefully some of this may be of use to the Collab.
