Happy Friday Everyone!
Here's a freebie for you all. Was challenged to create the SCCA Solo Nationals courses in less than hour this week. This ended up being the result.
Utilizing USGS data + Google Earth Data and the course layouts I managed to put together this one real quick. Th...
The long awaited next update! Thank you all for being so patient waiting for this. Matched to actual data provided from the teams (see photo above), this iteration brings accurate drivability, grip, thermals and overall a truly enjoyable racing experience.
The changelog doesn't quite do th...
Hi All,
Just wanted to give a proper update. Unfortunately the NightMare R update has been delayed until next week. But I promise you it will be worth the wait! A private project (the one in the photo below) is what took priority for me ever since finishing the MR2 so I've been a little ba...
As we approach the one month mark from the last BTM NighMare R update I wanted to provide a small update and a look into another project I've been working on for a private client.
BTM NightMare R status: I've been chugging away at the update on this. I've managed to fix the steering rack s...

2b or not 2b... that is the question! No really, it is. This update took a bit longer than I would have liked it to but, there are some pretty hefty changes that involved a lot of reengineering on my end that make the jump from 0.1 to 0.2 more stark than the average update. Overall however, the d...
2025-06-06 15:00:12 +0000 UTC View PostI've been hard at work on all of the 2025 updates and some QoL updates on the NMR. Main update being the tires. The Sleipnirs will remain the only publicly available tire. I toyed with the addition of the "Kotobuki" Cup tires, but between them having tremendously more grip and that serie...

Hello All,
Just a small update on the NMR's v0.2b progression! The hope was to have something released at the one month mark of the v0.1b release but we're swimming in new data for 2025.
With the real-life counterpart to this car's racing season underway we have been working with...

Hello All,
I am aware of some bug issues going on with the Spec P71 car on CSP version 0.2.8 and 0.2.9p1. I am currently in the process of resolving these issues. Note that the P71 is set for a yearly update so this preview breaking some stuff has unfortunately forced our hand to m...

It's officially happening, I've scheduled the release for the NightMare R! Excited to finally share this creation with the world. A full, from scratch, vehicle that is second to none in the physics department. Utilizing real-world data and the help from various racing teams as feedback, we've cre...

2025-04-01 07:00:13 +0000 UTC View PostBeen meaning to make this happen sooner rather than later, but, being that I am a 1-man Modding Team it took me longer to set up. But our website is officially up and running. Our public releases will all end up here eventually after they have been tried and tested here on Patreon. Hope you guys ...

NightMare R progress continues! We've finished off all the liveries we'll be including in the patreon beta release. There will be more with the public release later in the year. Driver Animations have now been handled, so that just leaves four things left before you all get to try this thing out!...

I've been working hard to crank out liveries for the NightMare R since the last update I shared. The goal is to give you guys as many liveries as I can to fill out a field of these cars for your enjoyment against the AI. Some of the liveries are loosely based on what you might see on a real car. ...

Tons of progress continues on the development of our next project "SleipniR". We don't officially have a name for the final car yet but that certainly hasn't halted our progress of development.
