It's time this car got an update for modern AC. I've learned some new tricks since 2017 plus obviously CSP is a thing now and the autoguessing was causing a few issues with the old girl... so with AlleyViper's seemingly inexhaustible willingness to help we've done what we can to bring her up to 2020 specification.

Physics have been given a complete working over. The bones were actually quite good despite being one of my first cars (the power of real data) but I've kitted it out with all of our latest features: fins for yaw drag, recalculated brakes with an LUT for the hydraulic proportioning valve, new inertias, tweaked suspension setup and completely overhauled tires. I also tidied up the setup options a bit, reset most of the F6 cameras and fixed a couple of annoying UI and log errors. I'm still waffling a bit on a few things, mostly in the tires, hence v1.99 and not v2.0... I'm open to feedback there.

On the CSP side there's been a total overhaul of the lighting, new paint shaders (the metallics... OMG the metallics) and a couple of little quality of life tweaks to a material here and a shader there. Once again, despite its age the bones here were quite good. Note that we can only do so much with this kind of non-invasive surgery - the wipers still don't work, for example, and there are a few other things that could only be further improved by changing the model itself - but that's up to Mantas. It's not ours to modify.

I've also gone ahead and updated all of the paint colors from my skins pack to work with the new paint shaders - rather than update that resource separately I've decided to just bundle it all into this one, so that one is now deprecated. There might still be some wonkiness in a few colors here and there or in this weather or that, so I'm also open to feedback here.

Installation:
First of all this update is not a complete car, so if you don't already have the XJ13 itself, go get it! It's not hosted at RD anymore but it is still publicly available. Please head over to the forum at assettocorsamods.net and download v1.0 there.

Once you have the car installed, start by deleting the data, skins, texture, ui and sfx folders from both versions. (Note that there are no updates to the soundbank or textures themselves, but I did remove some unnecessary files that were taking up disk space in v1.0. More extraneous files were removed from several of the skins as well. You'll have a smaller & cleaner install with no risk of version mismatches if you do it this way.)

WIth that taken care of, simply drag the contents of this archive into your assettocorsa root folder and select "yes" to overwrite when prompted.
