@philrob This is one that got me into modding, I absolutely must push it further. After this I must slow down may modding spree , I am doing way too much of it for two months now. But this is an apex of Jaguar, it is so unfortunate it didn't race, I think if it did race, Jaguar would have stayed on top. @Emery Yes Sayer definitely was bold about low drag. Besides that obviously proper aero balance, control of total lift produced. Supposedly, he even insisted that Jaguar badge needs to be painted on, because anything else disturbed aero too much, well that is a little strange with all of the rivetting, but maybe rivets don't spoil flow too much. However the problem is that they absolutely would have had to do K version to be more competitive everywhere else besides tracks of long straights. The same Porsche was doing with 907,908 and 917. Real problem must have been the Engine displacement regulations. And I think neither of those two had downforce But they probably had nearly neutral amounts of lift. Of course they both had measures to pick more airflow up above car at front, and force air flow upwards at the rear. That Porsche in particular probably had excelent aerodynamics. I think Jaguar would have had detachable tail too. Maybe slight lowered front end, and more body work coverage of frontal tire area. I wish Malcom Sayer worked for more decades on race cars. I think he would be known similarly like Norbert Singer is. There is no reason he wouldn't have been capable to change his mind from being all about low drag, to having some downwards force from aero effects. I think while looking at cars, in the 80s cars were obviously already all about downforce, but they also still cared a great deal about top speeds as long as there was full Hunaudieres in use at LM.
GT40 had a lot of work done over the years to reduce lift, but it was still lifting. Mk II had 100 lbs of lift total at 150 mph and the Mk IV had 148 lbs of lift total at 150 mph. Porsche had entered aerodynamic testing after the 906. The 908LH had 86 lbs of downforce total at 150 mph after testing with different nose designs. Obviously they were still learning lessons before they got the 917 right, but that might be because they were reaching new speeds.
Out of curiosity I just made a quick modelling to see how "more modern" lines would have fitted XJ13, I think it wouldn't have been ugly. Although I must admit rear end is difficult to style when lookign from rear angles. And for front end it is just very simple air dam and it works visually, and I am certain aerodynamically too, just question would be at how much cost of drag, it would have deflected air out away from front wheels, so that probably could have compensated. Reduced pathway downwards at rear end in angle and length would have already elimianted bunch of lift, and little spoiled would have eliminated some more. I wonder if some diffuser effect could have been extracted, but thats difficult with all the mechanicals in the way. To me it looks like if it could have been late 80s - early 90s supercar with these few small modifications. Hmm. Interesting, I can't believe though that MK4 had worse lift thatn MK2 at same speed. Perhaps taken the one of more slip streamed MK4, with rear deck that had stronger slope downwards and Gurney flap lowered way down. While MK2 with Gurney flap on more aggressive position + bigger front splitter lip (can be seen in photos they used them). It is always unclear with what particular setting these cars had those stated aerodynamic figures. Supposedly early GT40 had about 300kg of lift. Lola T70 supposedly had 200kg of downforce, but I assume it was with the most aggressive setup, like this one:
Working on shading and optimisation of model, also experimenting with new tire model. Not easy to balance it out.
^^There sure was a ton of aerodynamics experimentation with GT40. Hey I need advice, I am not satisfied with Cobra sound as placeholder. Is there anything better ? I think I might try to edit Cobra sounds abit, but I am afraid that they simply won't work, like my own sounds for D50 didn't work. Anyway. There is a little good progress. I have decided to sit for half an hour to try doing new tyres once again. And it worked great this time, so half an hour became three hours, car is lovely. I will also have base new tire for few other cars now. Besides that also worked on bare metal material for car #4 for soem reason all four pics happens to be from front. I am really happy with tires. And I would love to make fictional "what-if" body work, with short tail and air dam, I think that car would be sensational (theoretically, because no one will care anyway, but it would be interesting).
@mantasisg - I gotta ask how did you make the louvers? I mean apart from using an array. What technique did you use to punch them out with rounded corners?
Can't remember well, I did it 8 or 9 years ago. But I think it was rather primitive like I did them for w125 too. I just remember that it was an effort, and still I couldn't get them all neat. In XJ at the front they are also arent welded to the bonnet, it would have been too much of effort. And still everyone drives ripped one anyway. I remember it was unusual that I did 3d rivets. And it was super time consuming. With what I know now and skills, I could do them very much quicker. Everything was nothing comparing to getting body shapes right. And I couldn't have front radiator air intake right till I attempted photo matching.
Updating right now, it whateva its whateva Changelog: Code: It's whatever (whatever), it's whatever (whatever) It's whatever (whatever) you like (ooh) Turn this 아파트 into a club (uh-huh, uh-huh) I'm talkin' drink, dance, smoke, freak, party all night (come on) 건배, 건배 girl, what's up? Oh-oh-oh JK. This is true changelog of version 0.7: A lot has been changed. Tires physics model. Graphics. A lot. I still desire to do in undefined timeline (maybe never): Code: - might have redo wheels tires and rims - rims aren't perfectly centered - do pbr for tires - take on the rims blur hell - rain windhsield/wiper animations - fictional short tail body separate veh car + physics - headlights glass cover lit at night - mirror mask pbr - sportify some skins - add glass for gauges - do body rain descriptors - advance into optimisations - fine tune AI to be not too agressive and if too slow/too fast in places Big thanks for multiple people helping out with UI icons. Thank you @7bhp_Mk and @Mauro
This car, this Jaaaaag, is too sexy for rF2 and for rF2 workshop. So I am assigning these descriptors. Hopefully, it will expose mod towards right people. And protect it from clueless innocent children.
Looks like there has to be little bit updating eventually. Although I haven't heard anything bad about it. Along these will come, at first through my Discord for testing, before they get developed further and then get listed in steam workshop. https://discord.gg/XuvmKmr3 Looks good.
