As a scratchbuilt car, it's pretty awesome. It drives like a dream. It's really fun to drive. I think the mileage might be off a little as 30 liters only lasted me a few laps at Mugello. Tires are great. It's really fun to drive.
There are a few issues some of which are an easy fix, some of which will take more time. In CM, it doesn't display correctly in the showrooms for some reason (missing body texture, super dark - I think this might be a shader issue). In game, the textures display correctly.
There's no interior glass texture, so the windshield and side glass are invisible - easy fix. The center mirror is not adjustable, but the side mirrors are. Between the hood (bonnet) and the interior, you can see the ground (simple fix), and the interior digital display is floating above the dashboard, which you probably only notice in VR, but which stands out a lot. This is also a pretty easy fix as you just need to adjust the position in the digital_instruments.ini. The fuel gauge isn't implemented, but that's not a big deal (difficult fix). There's no exterior AO layer (I think) and so the shading on the diffuse layer really stands out in VR, though I'm sure it's fine outside of VR. You can make an AO layer in CM and apply that. Interior detail layer is a bit too large in terms of the detail repeat. So the tiny textures look huge in VR.
Again, amazing car. It just needs a few tweaks. I'd also raise the noise level for the wind as I'm sure most people will drive this with the top down.
Also, you can put the roof animation in as an animation for a "wing" and then put the roof animation in the AERO section of the setup.ini. Then people can raise and lower the roof in the setup vs tying it to the lights. But that's up to you. Write me at feintgames.com if you want to know more about how to do that.
