MAK-Corp Group C Mod v1.1
- 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.

Nice mod. Sauber degrees of rotation should be as the other 2 cars, thus 540 and not 360!

Any Knowledge if you guys will be adding the rest of the Group C Era cars to the mod? like the Jaguar XJR-9/12/14, Peugeot 905, Nissan R91CP, Spice /E88P/E89C/E90C, Lancia LC2, Toyota 88CV/TS010, Etc.
This mod great so far but the field is rather flat with the mostly being 1 of 3 cars, I'd love to see variety in the field

Awesome mod loving it great job

The AI in rF2 is well known for this behavior, specially if you don't do the practive/qual sessions.
Tip: do at least the qual session (even accelerated), let the AI do some laps to "know" the track before jumping on the race. Also, AI is very track dependant - you can't simply put it on 100% and expect that they drive the same among different tracks. On some tracks, you may need to lower their skill to 90 or even less sometimes - otherwise they simply "cheat" because running on simplified physics.

The AI is way too fast. I always have to turn the boost fully on to remotely hold their pace and I'm a decent driver. Their acceleration out of corners is unreal. They behave like a modern F1 car. Car Model 5/5
AI 1/5

For porsche and mazda have to reduce the ffb mult. from 1.0 to 0.65 otherwise clipping.

Love the mod...
For the Porsche... is there a way to disable traction control and abs? It is set to 1 in the car setup menu without a toggle option. As it is, get no traction loss with wing set to 0. Only time car looses traction is if tires are overheated.

Many thanks for your hard work - don't let the negative comments put you off making this mod the best it can be. I love the C9 Sauber from PC2 which is what got me here.

Too easy to drive, leave ABS and traction control
Donat_Prodan Mar 21 @ 11:56am 
Terrible AI, waay to quick, too much grip (they brake waaay later, 100% brake pressure, they never lock up, unreal grip out of the corners, they just launch themselves out). Fix this, very, very poorly made and it seems like I'm not the only one complaining. 2/5.
