Stock Parts Rework

This mod adjusts the mass, lift, power and ammo count of many stock parts. It does not alter mesh, surface, buoyancy surface, voxel shape, hitbox, logic node or cost properties in order to maintain a level of compatibility. It primarily focuses on mass. Some components, like basic blocks, become lighter, while some others, like engines and seats, become heavier.

It is a known thing that buoyancy and air drag at high speeds are far from ideal in Stormworks. Stock mass of engines are quite low considering the power they generate. If air drag was lower, an airplane with small engine would reach crazy high speeds. If buoyancy was correct, ships might not sink. In addition to the issue of most components being lightweight, payload is also quite light such as fuel and characters. Fuel in vehicles weighs only a fraction of what it should. Player and NPC characters weigh only 3 mass when in seat. As a result, it is probably possible to design a helicopter with small diesel engine that can have hundred passengers on board and enough fuel to carry them thousand kilometers, far exceeding the map size. So, this mod aims to mitigate some of these and make the game harder and more sensible, at least in my opinion.

DISCLAIMER: Converting stock vehicles to/from this mod will likely require rework of powerplant and center of mass/lift/thrust. Vehicles made of mostly basic blocks may become lighter such as ships. But smaller vehicles will become heavier than before such as cars and aircrafts. For small and heavy sea vehicles, downward water propellers or pivot & wheel glitch can help with weak buoyancy. If you don't know yet, Stormworks waters is 100kg/m³ dense. Also worth mentioning that using negative mass glitch to get buoyancy for seaplanes, affects the mass not only on waters but also in the air which makes it the opposite thing that this mod aims for.

If modding of buoyancy, drag, fluid mass become possible that would give better opportunities to further enhance realism in Stormworks.

Comment, ask, criticize about the changes explained below divided in to categories. Better feedback is as detailed as possible.

There are components whose mass I didn’t change because they seemed mostly fine, such as pipes, sensors, buttons, and windows. Additionally, there are components I haven’t adjusted yet, like certain parts in the weapons category and the entire 'Industry' category. Some components, such as wheels, gas tanks, and heat exchangers, were not changed due to power or balance issues.

There is hidden mass on some components similar to fluids having mass but not shown in the vehicle editor. Some of these are consumables such as ammo and solid rocket fuel. Some others come with components that have moving parts such as doors, propellers and wheels. Don't confuse with mass of child part of the multibody components such as pivots, their mass are shown in total vehicle mass in the vehicle editor. I take hidden mass in to account when changing mass of components.



- 1x1 crankshaft sound changed to medium engine's old sound.
- 1x1 electric motor sound changed.
- Rotor (Light) and Rotor End (Light) sound changed to Aircraft Propeller sound.
- Aircraft Propeller sfx range increased.

- Informative descriptions, but currently not possible because overriding stock parts.
- Since it is work in progress, anything may change based on feedback, research or gameplay balance.
- More components may be included.
