Cars - 2007 Subaru Impreza WRX (GD) Tuned (2)

Finally, after five years of work & trying to get a release together for at least the last 3, it's ready. This is the Assetto Corsa incarnation of my real-life daily driver/project car. I bought the car secondhand in 2010 and left it alone for the 3 years it remained under warranty. At one point the front control arms were recalled by Subaru over rust concerns and I decided to just go ahead and replace them with aluminum arms from the STI. At...

It looks great, but it seems to be missing the LODs. Perhaps that could be done in the future?

I love this car. Like all of your cars, its handling is sublime.

I do hope LODs will come.

In the meantime, I could save my GPU from overexerting itself by setting up races with other (perhaps Japanese) cars on the grid. Would you be able to give an idea of which Japanese cars in AC's roster (including Kyuubey's data replacements) would be suitable opponents on a grid?

Maybe, once we polish the last bits, but not now, it'll be a nightmare to update along the rest of the LOD models. So being a road car is not a priority, really.

Car has blank AO in the KN5 and 8mb .dds in every skin which is very inefficient. AO template could use a render that is actually readable.

Other than that great work as usual.

There's a reason for that, nothing inefficient about it. Skin folders below 20mb are perfectly fine, no need to include the 8mb file on the kn5.

I mean, it gets loaded into memory either way. The difference is including a single 8mb file in the KN5 or including 12 of them in skins folder.
Why not just bake it in 1024 if size is an issue?

That's my point, nothing inefficient about it. And it's not blank, it's AO, does it's job.

The diffuse texture inside the kn5 is blank. I'm well aware that actual AO is in skins and what it does. But hey if it's more efficient that way then I guess kunos and everyone else has been doing it wrong ever since.

How can it be possible that the engine at 0rpm produce 156Nm ?

Never said it's more efficient... just telling you there's nothing inefficient about the way it's done now, like you pointed out. No need to do a low res 1024 map either. Yeah Kunos did that, it was 2014... Cars - 2007 Subaru Impreza WRX (GD) Tuned (23)

It's only inefficient in that you have to copy it to every new skin. Personally, I agree that it makes more sense for it to just be in the kn5 (why necessitate copying it every time if you don't need to?).

Awesome work. Is there a thread anywhere where you could cover the 'making of' this mod? Be very interested to see how you did the photo scanning etc.

I have RCE "Regular Guy" springs on GTWorx bilstein suspension and whiteline RSB on my 2011 wrx. I put your mod list in the description of the car in CM. You have a CF driveshaft IRL? Daaaaaaaaaaang.

Oh, one small surprise was when I clicked on the fogs and I freaked out because they are the perfect color. LOL
