Lots of important fixes, tweaks, and some new features are coming at you in this latest update to the opt-in alpha of the game.

If you want to check it out and have not opted in yet, you can do so by right-clicking the game in your Steam Library, choosing Properties, Betas, and select the openbeta - 4.2 alpha testing branch.


Making the underlying NA torque curve visible is surprisingly useful. Also… twin-scroll!

General Fixes

• Game engine got updated to its second patch version, UE4.27.2
• Decreased game launcher height so it fits on smaller resolution screens
• Fixed possible way to fixture nuke two cars simultaneously with undo and cause "jello cars"

• Big performance increase for high-fixture-count cars

Gameplay

• Fully fleshed out stats for the various intake options
• Tweaked intake flow limits and made compact intake more viable
• Tweaked cam progression tfor more usable range, cam 0 is now = 15, 100 still is = 120
• Reduced quality effects on baseline NA torque to make more realistic Nm/L figures
• Fixed entertainment weights being way too high
• Tweaked all fuel system prices
• Added a dashed "base NA equivalent" line to the power torque graph for turbocharged engines
• Tweaked flow reductions of all muffler types and catalytic converters
• Fixed loudness inconsistency in intake options

Turbos

• Added twin-scroll turbos
• Added race tubular turbo headers option (graphics not in yet, but next patch!)
• Added much more cam dependence into turbo spool point
• Revised intake & header resonance effects to be more realistic
• Revised spool behavior based on turbo size
• Tweaked compressor map progression to not require as much quality for modern turbos
• Tweaked turbo AR ratio progression with Tune slider

Design, Art, Content

• Added a ruler fixture for all your measuring needs
• Fixed engine bay sizes on 11_Eu_Super families which were too small
• Fixed body material issues with 10scoupe02large and 10scoup02_large_convH
• Fixed 10sCoupe02 Series and 00s_Van_Lowroof that got corrupted for 4.2.4
• Fixed custom paints having incorrect sizes when applied to scaled fixtures
• Fixed very poor performance of Desert Gas Station photoscene
• Fixed extreme light strength in reflections in Modern Studio by default
• Fixed a bunch of weird / inconsistent seat row limitations for various car bodies
• Fixed cloth paint material scaling incorrectly with different objects

Modding

• Updated SteamWrosk SDK to 1.52 and addressed a startup crash
• Fixed numberplate material missing from SDK tools
• Added Steam workshop / exporter categories for rocker covers, props, and custom paints

Loads of issues and features to work on still before a beta, but things are coming together nicely and the alpha is becoming more playable… and hopefully enjoyable… with every patch.

Thank you to everyone helping out by reporting issues!
