Known problem
- SIC Kart Land track surface vertex smoothing was not set, which only affected the visual effect. I was focused on fixing kerb and forgot to do it.
- SIC Kart Land fuel consumption prediction was inaccurate (significantly higher than actual fuel consumption).
- SIC Kart Land, when returning to the track from grass at high speed, the outer edge of some kerb would cause the kart to take off.

Possible problems
- When "Special Effect" is set to the highest (Full / Ultra), if there are multiple cars on the west straight creating chassis sparks, the frame rate will drop sharply (actual measurements have nothing to do with the number of materials or models. When only the track surface and grass are retained and all PBR rendering is removed, there will still be a sharp drop in the frame rate, and it has been verified on other tracks).
- Since I replaced the RTX 3070 Ti (8GB) with 7900 XT (20G) last year, some problems that may be caused by insufficient video memory cannot be fed back in the self-test.

P.S.
This is a free mod, Please do not use it for commercial purposes.

- GP Layout is a conversion mod, it's only used to communicate and learn game
material rendering technology that use gMotor engine, please do not use it for commercial purposes.
- SIC Kart Land is a scratch mod, Modeled by "driver" (eaf1 or chnf1), "fox", "Sephi-At", please indicate the source when reprinting or converting the kart layout, Please mark "Sephi-At", please do not mark "速效救心完".

==================SIC Kart Land==================
================Developer's Message================

- SIC Kart Land MOD is a karting track completed by "driver" ( from "eaf1" or "chnf1") and independent modeling expert "Fox" in 2009. After its completion, It has not been released to the public since its completion.
- In November 2013, "driver" decided to publicly release this track MOD so that all racing enthusiasts can experience, communicate and racing online on the simulator. However, the completed version from 2009 was lost when the old hard drive storing its data was damaged in 2011. In desperation, "driver" rummaged through boxes and drawers and found a burned CD, he was lucky enough to rescue some 3DSMAX files and some game files in rF format (.gmt), so he worked with "Sephi-At", who is also from Wuhan, to modify and improve the track MOD. The interesting thing is that no matter "driver" from Wuhan, "Fox" from Kunming or "Sephi-At" from Wuhan, none of us three have ever stepped on this famous track. All data was obtained by measurements and photography taken by "eaF1" (or "chnf1") members "YW25", "seafly", "下雨天才" ("Rainy Genius"), "beba" and "Fb" at the SIC Kart Land in 2009. Of course, the core data is still derived from data provided by the Shanghai International Circuit.
- As "driver" is currently suffering from cancer, he is unable to carry out the broken surface modification of the first corner of this track. The workload is too heavy. "driver" is currently undergoing treatment and is mainly bedridden, so he cannot sit for long periods of time. he hope everyone can understand. In fact, "driver" is very afraid to make a MOD for such a well-known track. After all, it has been run dozens and hundreds of laps by people in the field, and they have a direct understanding of SIC Kart Land.
- Finally, the track MOD's ground infrastructure will not be updated for another year. After "driver" personally gets to kart on this track and completes two laps, further refinements or rework will be considered. However, "driver" also admitted that he currently has a urine bag and small intestine hanging out of his belly, and wonders if SIC Kart Land will still allow him to drive there.

driver 2013.12.3

================================

- My first time running this track MOD in rF was incredibly exciting. Same as "driver", I'd never actually run on this track in reality, I'd only seen onboard videos. But actually running on the track MOD, I have to say "driver"'s modeling skills are truly superior, especially when they're modeling solely from data. The main track and most of the modeling were done by "driver". When I took over, the track was already pretty complete, so I simply scraped a few building models online and started working on create AIW driving line. "driver" wasn't in good health, but he still did a lot of repairs, which made the progress quite fast.
- When I posted the progress screenshots and videos, I received a lot of feedback about the lack of gradient. I'm not sure if it's because of the onboard view, but I always felt that the track had a significant gradient during my tests. But since I haven't actually run on the real track, I can't really say for sure. This was my first time working with "driver", and I hope to have the opportunity to work together more often in the future. (But this is actually my last time work together with "driver")

Sephi-At 2013.12.4

================Date dividing line================

- 10 years later, I've finally remastered this track MOD from rf1 into rf2. In 2023, I completely remastered the road model in 3DMax, repainted the textures, and created a full PBR render for rf2. Other details were also refined based on the 2023 onboard. This is a commemoration of the past decade. Thanks again to "driver" for inviting me to work on this track MOD 10 years ago. This is the last track MOD "driver" has ever produced and released, and I hope you'll enjoy it and remember it.
