Valkyrien Skies Copycat Mass Fix: Accurate Physics for Create Contraptions
If you have ever built an airship in Minecraft using Valkyrien Skies and the Create mod, you know the thrill of watching your mechanical marvel take flight. Copycat blocks from Create are essential for adding detailed slopes, panels, and decorative shapes without bloating your block palette. However, a long-standing quirk has frustrated engineers: the mass of copycat blocks in Valkyrien Skies often defaulted to a generic, inaccurate value. This made ships behave unpredictably, with some decorative sections weighing far more or less than they should. The Valkyrien Skies Copycat Mass Fix datapack finally addresses this problem, bringing realistic physics to every copied texture and shape.
Why Mass Matters in Valkyrien Skies
Valkyrien Skies is a physics engine that simulates rigid bodies, buoyancy, and inertia. Every block attached to a ship assembly contributes to its total mass. That mass directly affects how the ship accelerates, floats, and responds to forces like propeller thrust or balloon lift. When copycat blocks are treated as a single uniform weight regardless of their size or the material they mimic, even a beautifully designed hull can handle like a brick. Accurate mass distribution is not just about realism — it is essential for balanced gameplay and stable contraptions.
What the Copycat Mass Fix Datapack Does
This datapack overrides the default mass values that Valkyrien Skies assigns to Create copycat blocks. Instead of a one-size-fits-all number, it calculates mass based on two possible methods:
- Size-accurate mass: The mass scales with the dimensions of the placed copycat block. A full block weighs as much as a standard block of that type, while a thin panel or a small wedge weighs proportionally less.
- Material-consistent mass: The mass matches the real block the copycat is imitating. A copycat panel textured like oak planks will have the same mass as an oak plank slab of equivalent volume, keeping consistency across your build.
The result is that your ship's center of mass shifts naturally when you add or remove decorative elements. No more mysterious sinking because a handful of copycat stairs somehow weighed as much as an anvil.
Supported Mods and Blocks
The datapack casts a wide net, ensuring compatibility with the most popular Create add-ons that introduce copycat variants. The following are fully supported:
- Vanilla Create copycats (slabs, stairs, panels, and more)
- Create: Connected
- Create: Copycats+
- Additional copycat blocks from other lesser-known add-ons (check the gallery for specifics)
Each block type is individually mapped to a corrected mass value, so you do not have to worry about manual configuration. Simply install the datapack and watch your ship's physics become instantly more believable.
Installation and Important Notes
Installing the Valkyrien Skies Copycat Mass Fix is straightforward. Download the datapack file and place it in the datapacks folder of your world save. If you are on a server, the datapack goes into the world folder on the server side. One critical requirement: you must restart your entire game after adding the datapack. This is not a bug in the fix itself but a limitation of how Valkyrien Skies loads mass overrides. A simple world reload or rejoin is not enough — a full client and server restart is mandatory for the changes to take effect. For players who enjoy a streamlined modding experience, managing such datapacks becomes effortless when using a modern launcher. The foxygame.net launcher, for instance, lets you browse and install mods and datapacks directly from its menu, keeping everything neatly organized and automatically updated without hunting through folders.
Fine-Tuning Your Contraptions
After applying the fix, you may notice subtle differences in how your ships handle. A lighter superstructure made of copycat panels will allow for faster ascents, while a heavy, full-block replica of stone will sink more realistically. This opens up new engineering challenges: you can now deliberately use lightweight copycat blocks for upper decks and reserve full blocks for the keel, creating a stable center of gravity. Test your designs with small adjustments and watch the mass readout in Valkyrien Skies' ship information panel to see the corrected values in action.
Why This Datapack Stands Out
Many physics tweaks for Valkyrien Skies require complex configuration files or custom mods. The Copycat Mass Fix is a pure datapack solution, meaning it is lightweight and does not add any new blocks or items. It works silently in the background, respecting the original textures and shapes you love. The community-driven effort behind it also means it is regularly updated to support new copycat variants as they appear. By solving a niche but impactful inconsistency, the datapack elevates the entire Create-Valkyrien Skies crossover experience from a fun experiment to a polished simulation.
Conclusion
The Valkyrien Skies Copycat Mass Fix is a must-have for any builder who wants their flying machines and naval vessels to behave as good as they look. It corrects a fundamental oversight in mass calculation, making copycat blocks behave logically based on size and material. Installation takes only a moment, and the payoff is immediate once you restart the game. Whether you are constructing a delicate airship with intricate paneling or a colossal warship clad in copycat stone, this datapack ensures that physics no longer punishes your creativity. Embrace accurate mass and let your contraptions soar with the realism they deserve.
