Procedural River works without GIS data. “Real Map Reference” georeferences the simulation to the selected map location but does not infer navigable depth from OpenStreetMap.

The simulator remains fully usable if map tiles are unavailable.
BARGE LIBRARY
Barges, loading & convoy
Pick a design, set what it is carrying, then make up the tow. Mass, draft, centre of gravity and under-keel clearance in the simulation all come from what is configured here. Figures marked ESTIMATED are engineering estimates, not published data.

Engines & driveline
Configure each engine independently. Rated engine power is converted through the gearbox, then balanced against the propeller torque at every physics step. Published fuel points are preserved; values between them are interpolated.

HELM applies cabin filtering automatically. Mixer levels are saved in this browser.
ADVANCED WATER LAB
Real-time optical and flow calibration
Advanced calibration is available when Water FX is set to Ultra or Photoreal HDR. Select one of those modes in Environment to activate every control.
OPTICS & HDR
MOTION & CURRENT
Sampled at vessel—
At 100%, the surface pattern follows the same local current field used by vessel physics. Set it to 0% to keep only wind/wave animation.
BOW WAVE & RETURN FLOW
Near-field solverGPU HEIGHT FIELD
The bow crest, hull depression and stern return flow deform the surface, then propagate and decay according to the selected water response. Floating vegetation samples an analytical version of this near-field flow.
FOAM & INTERACTION
FLOATING TARULLA · FLOW TRACER
Tarulla clusters are passive visual tracers: they sample the current independently at each position, reveal bends and shear, and do not alter vessel physics.
The browser sends data only to the local RiverTech Bridge. The bridge performs UDP broadcast/unicast/multicast, TCP, and serial I/O for the external chartplotter. Use 38400 baud for the complete default sentence stream; 4800 baud cannot carry every enabled sentence at these rates.

DETECTED GAME CONTROLLERS
Connect a controller, press any button on it, and scan again.
Select an action below, then move or press the desired control.
LIVE AXESMove each control
Axis readings will appear here.
BUTTON TESTGreen = pressed
Press a button on the joystick or quadrant.
BRIDGE CONTROL MAPPING
Select BIND on an action. For an axis, move it at least halfway; for an action, press its button.
USB HID DIAGNOSTICS
Use this only when the device does not appear in the game-controller list. HID detection identifies the device; its raw protocol needs a model-specific mapping.
First use this panel to confirm that the axes and buttons respond. Accepting the control enables rudder and engine commands in the simulator.
