LvxMagicks - Better Car Spawner

ATTENTION: You have to have the DLC purchased to add the DLC cars to the Mix, there's no way around it.

Better Car Spawns for Car Mechanic Simulator 2021

Lvx Better Car Spawns is a complete overhaul of the vehicle generation and randomization systems in Car Mechanic Simulator 2021. It replaces the repetitive vanilla spawning algorithms across the Junkyard, Barns (Sheds), and Auctions (Normal and Salvage) with an intelligent, synchronized engine designed for maximum variety, anti-repetition decay, and long-term fairness.

In the base game, visiting locations like the Junkyard or Barns frequently spawns the same small cluster of vehicles over and over while leaving dozens of installed models untouched. Junkyard lots are often mostly empty, and auctions suffer from limited variety.

Lvx Better Car Spawns resolves this by building a dynamic vehicle database directly from the game runtime and applying smart weighted roulette selection. Every base game car, DLC car, and Steam Workshop mod is recognized as an independent candidate per configuration. The mod ensures unique models per visit, severely penalizes recently seen vehicles, and increases the spawn chance for vehicles you haven't seen in a while.

Key Systems

Dynamic Runtime Vehicle Database The mod discovers every valid vehicle and configuration version currently installed and recognized by CMS2021. Each configuration variant is treated as an independent candidate. There are no hardcoded vehicle lists, meaning newly subscribed Workshop mods and DLCs work immediately.

Anti-Repetition and Fairness Decay A multi-tier FIFO history queue tracks recent spawns globally and per location. Exact configurations spawned recently receive up to a 98 percent penalty to their selection weight, while models seen recently receive moderate penalties. Underrepresented cars that appear less frequently automatically gain higher spawn probability through cumulative roulette selection.

Same-Visit Model Diversity Whenever you visit a location, the engine prevents duplicate vehicle models from generating in the same lot or catalog as long as unpicked unique models exist in the candidate pool.

Full Spawn Point Population The Junkyard can populate all 24 valid spawn positions instead of the sparse vanilla 10 to 40 percent fill rate. Barns can fill every available vehicle module slot, and Auctions can generate full catalogs up to your desired limit.

Parts Pile Discoveries (Barn Maps and Loot Cases) Configurable quality-of-life options allow you to guarantee finding a Barn Map or a Loot Case (Chest) on the very first parts pile you search during a visit, removing tedious RNG when looking for new barn locations. Both options are disabled by default.

Non-Invasive Persistence Spawn history and configuration settings are stored externally in the mod directory. The mod never touches or alters your vanilla game save files or vehicle config files.
