Full length floor + temporary bulkheads

I’ve layed out all of the bulkheads and placed a full length floor + temporary lighting in the internal scene. I’ve also added a few baked shadowmaps to the diesels to test out baked lighting.

This gives a great perspective on the size of the UBoat and will allow me to continue adding in more and more details. My focus will continue to be the electric and diesel rooms before I moved off to the other compartments.

Starting Diesel via Air Flask

You can now use the high pressure air flasks to start the diesels. I’ve also added in a flashlight, zoom, and interaction system to allow you to turn valves, switches, knobs, etc… and updated the air piping and diesel details.

As always, if you would like a true UBoat Simulator, help shape it by giving me honest feedback! Have a great weekend!

Diesel engine room

I’ve been working on the diesel engine room; added some textures, sounds, and animations. Haven’t yet baked lights for the prototype.

I also bought an amazing book from Amazon written by the son of the founder of Cummins Disesel. I’m hoping to use info from it to correctly update the 3D model and ensure I have an accurate simulation under the hood for the Krupp Germaniawerft F46A6P diesel most VIICs used.

Would love any feedback and as always, the updates are live in the sim.

Diesel starting air tank

The M.A.N. Marine Diesel Type M 6 v40/46 engines were started and reversed using air tanks. Each diesel engine had a 125L air tank that held air at 75 atm. A pressure reducing valve stepped the pressure down from 75 atmospheres to 30 atmospheres to start the engines.

For the latest release, I’ve added the simulation aspects to use air to start or reverse the engine. For now, no main air manifold is present so the tanks will not refill. After a single start, they will fail to restart again.

Double click the diesel motor to get more info on the engine and specs. As I dive deeper into the sim, more of the underlying components will be made interactible on the 2d schematic.

Power-plant / drivetrain

One of the most important aspects of a deep simulator is the ability to override the automation of certain systems and have full control over all settings. In a U-boat, the power-plant is arguably the most important system; it moves the boat, and charges (or discharges) batteries, blows ballast tanks when surfaced etc.. . Without the power-plant, the U-boat is useless.

In order to simulate an accurate and fun system, I have pulled specs from the VIIC manual. The main powerplant layout includes two banks of motors, engines, 2 clutches, and the propeller itself.
