rF2 Group C Mod Update 1.jpg

The impressive Group C mod for rFactor 2 has been updated - now at version 1.1.

Developed by the MAK-Corp sim racing modding group, and available for Studio 397's rFactor 2 racing simulation, the Group C Mod is a three car collection of some of the most iconic, powerful and impressive racing endurance cars ever created - and it is available for free for us to enjoy in our virtual racing hobby!

Containing the Sauber C11, Porsche 962C and Mazda 787B of the 1991 WSC season, the cars are a truly wonderful representation of one of the finest eras of sportscar racings long and illustrious history. Featured unique and detailed physic sets for each machine alongside all the latest rFactor 2 goodies available within the increasingly impressive sim, this new build to version 1.1 is indeed a welcomed and pleasing update to what is already one of the standout pieces of content in rFactor 2.

Available to download now from the Steam Workshop, you can check out the V1.1 update notes below:

  • Removed inside double skin 3d mesh for all cars bonnet glass - with new shaders since last update, is no longer needed.
  • Fixed dark side windows on 787b, now looks like other cars.
  • Animated wipers added to 962c and C11.
  • All wipers are fully operational and clean glass etc.
  • All windows for all cars re-exported with new uv for rain.
  • Rain on all car bodies/banner has been added and water direction movement configured as well.
  • Re-exported all car liveries with removed wiper shadows inside them because they now move and look wrong.
  • Edited and re-saved the Templates pack with all car changes if templates are wanted by you guys.
  • All cars have new backfire instead of old backfire - thanks s397.
  • RPM light added to 787b.
  • Lods made and added for all cars.
  • Improved mirror mapping on all cars

Rain racing - Please disable reflections in-game when racing in rain due to reflections in wet weather not working correctly on windscreen areas outside of the wiper clean area and because these windscreens have a lot of non wiper area compared to most due to windscreen shape, therefore making it more visible.

Apologies for another template change, it was un-avoidable and had to be done to accomodate rain support properly.

I had first rF2 online race with them today. I love C11.

I found car weird online, but really liked it in singleplayer. How to understand that ?

Great update :thumbsup:

This was really something in when it was F1'99-02's and later rF1 mod. I still have cd/dvd's where I burned whole installations..
F1 2001 had best looking sports car models by VLM..... imo
'01 had 2048x2048 textures, cars had smooth wheel arches
'02 and F1C were downgraded texture size
Never looked quite as good.... imo

I just been loving these cars in AC and now an update for rF2 versions! Thank you so much:)

Honestly, I'd care less about the graphics at this point in my sim racing hobby when I need to put out 4 to 600 dollars just to play in 2018 graphics like ACC. While all I need is second hand R9 290 or GTX 970 to play RF2, AC1, and iRacing with 'decent' graphics. But anyways, I really appreciate the effort from S397 and third-party creators. All I am waiting for months now is for RF2 to be back at SRS.

Imagine an excellent mod like this in a amazing physics simulator as rF2 running under a decent graphics engine and not 2004 graphics. Dream.
If that is the first thing you have to say about someone's work that you get for free, I imagine you may have lost your common sense. What would really be a dream is for some community members to grow up from the current kindergarten state they slipped in.

Durge, I think these began as a mod for Nascar Racing(the last one prior to Kammerer buying the company back from Sierra) Then they forced the mod makers to remove the mod, only allowing it after some changes were made.(I forget what tho) These would have been the closest to what became iRacing.

Back on topic, these cars are brutal! FFB is very strong compared to other cars. Made me sweat on the big mige.

I'm loving the mod. Three cheers for the boys on this one. One of the biggest, baddest eras of motorsport..

This mod actually got my inquisitive nature running to go look at the RF2 physics calculator immediately went "damn, I already thought that was a tonne of work, now I'm *really* impressed".

The fan boys are a bit much to take. That comment about graphics is not really off the mark. As much as I love the physics and ffb of rf2, man, the graphics are just painful. I think all he was saying was, wouldn't it be nice if it looked at least as good as say AC. That would be a dream. I can't imagine who would disagree that the graphics in rf2 could be improved.
