This picture shows the terrain used for these road-movement tests.
The two hills which show in the pictures are marked by two whitish-sand landscape texture tiles and a
pair of trees. At this point in the testing, the 'Scenario' road section is in place,
but the 'Landscape' road section is not. The 'further hill' referred to in the pictures is the one on the right.
During the tests, the portion of the road on the right that shows no 'Landscape' road pattern was changed. 'Scenario' road and/or the 'Landscape' road sections were added and removed.
This picture shows two pairs of 10-meter-high pixels placed across a road.
To mark the place where the pixels were, the whitish-sand landscape texture tiles were used.
Additionally, a tree was placed on each side of where the 'high' pixels showed on the
Scenario Editor landscape map.
Then, using the 'Landscape' tab, a road was run straight across both pixel pairs.
Then, using the 'Scenario' tab, a 'road' for use by AI was run across the nearer pair stopping short of the further pair. On the far side of the second pair the AI road was continued.
You will notice that the far pair shows a 12-meter-high (10 x 1.25, as always) hill such as you would expect from a pixel value of 10.
Note the effect of the 'Scenario' road on the nearer pair of pixels. That 1-meter-high by 4-meter-square bump is all that is left of the 10-meter-high pixels.
This picture shows the further hill with the 'Landscape' road (but NOT the 'Scenario' road).
The 'Scenario' road stops this side of the further hill and picks up again on the other side.
The 'Truck.RRF' Opel Blitz is under AI control and is going away from us along the road.
The steepness of the hill does not matter to vehicles, either trucks or tanks, under AI control.
This picture shows the further hill, still with NO 'Scenario' road, and
with the 'Landscape' road removed.
The 'Truck.RRF' Opel Blitz is under AI control and is going away from us along the road. The truck has just turned aside to go around the hill.
All vehicles, trucks or tanks, under AI control will avoid such a hill with NO 'Landscape' road WITH or WITHOUT a 'Scenario' road.
This picture shows the the same road, but an 'aaBridge.RRF' bridge has been added.
The 'Truck.RRF' Opel Blitz is under AI control and is going away from us along the road. The truck has just turned aside to go around the bridge which it seems to consider an obstacle to be avoided.
'Truck.RRF' Opel Blitzes, 'Kfz1.RRF' Kübelwagens, 'Truck4.RRF' US 6-ton 6x6 trucks, and a 'Willys.RRF' US jeeps will not cross the bridge under AI control. As far as I can tell, all tanks and armored cars will cross the bridge.
