GP4: 2021 Aston Martin Livery (on RP20 shape) lower lods added

I wasn't intending to put much effort into this car, yet I'm on the third update! Glad for the feedback, but I really must concentrate on new work like the actual 2021 shape😄. 

Anyway, I've added lower lods to the package. I personally only run the main lods, so I've not tested these, but they should be OK. 

V1.3 is available on the same links as before: 

Lods, if you don't know, are lower spec versions of the car which are shown at different distances from the camera. So when the car is close to the camera, you can spot all the details, so you want the most detailed version. At middle distance, you want to just have basic shaped versions of the main parts of the car. And then when the car is a dot in the distance, you have a very basic version of the car.

lod 0 & 1 (~40,000 faces)

lod 2 & 3 (~9,500 faces)

lod 4 (~1,300 faces)

When you have a full grid of cars, a lower end PC might not be able to cope with all the highly detailed shapes loaded, so that's where the lods come into help. 

There is a similar thing that happens with the textures, known as mipmaps in GP4, where again, the further away the car is the lower the texture resolution and thus lighter to run on a lower end PC.
