Walrus Cove, at least now I can say I'm one of the few people that made a looping. Currently 1% of AI uses it because there's no escape for them if they don't make it currently. Alone they make it 100% but as soon as there's more there's always someone that gets stuck and next lap they drag the ones that made last round down with them. Unfortunate I had to deliberatly adjust the race track so 24 cars won't drag around 10 of them roughly into the looping path, they still do it sometimes but I can't push the track futher now.
Lamps are destructable on the new map and are illuminated, but you shouldn't ever reach them I think, but in case you do they'll explode in a thousand pieces it wasn't merged it's all tiny pieces if it breaks. Not sure I can add fake (baked) lighting if it's destructable I'll cross that bridge when I come to it.

Probably the biggest update this mod'll ever get, everything's changed basically: Everfrost Peak and Hot Top Volcano Reverse added, with changes to every other map following:
Ancient Lake: Now properly filled, screenshots from high up now look a bit better
Start flag merged into one model and texture to get rid of these annoying connection points
Because I can animate now I've added the rotating key, I think I can't remove it's collision it's solid don't collect it.
The ground Nintendo is now illuminated so it won't be half dark half light.

Fossil Canyon: World holes filled, enjoy the low poly world roof and edges
Flag merged, of course all of them have it I got rid of the old 4 textures it would be pink otherwise

Jungle Falls: AI route redone, smoother and more AI friendly, but 24 cars still cause major mayhem
Invisible walls around the temple to encourage AI to not be stuck there for several hours. Same with all dino foot prints they're now all filled and actually flat, UV on all sensitive textures redone and cliffs simplifed, hopefully there's no flying grass
World holes filled, it looks gorjeous from far up

Hot Top Volcano: Reverse route possible, excuse obvious invisible ground it's for the AI you see
Cave shortcut extended a bit and smoothed for the reverse route
All sensitive textures adjusted, except the ones below the magma but the magma doesn't wave around (yet) and it'll be better to be replaced with a full magma texture anyway
Magma connected to road received it's custom transition texture, it's a bit obvious but it's worth the look

Sorry about the new weather on the winter map I tried to remove the bloom that appeared but it's still quite glaring, I tried smoothing it with more objects but it just created more problems it's as good as gigantic flat planes can get now, I had to UV the ice roads manually, probably should've just created a new smoothed road from scratch, at least it's roughly 80% smoother than the original it was a plane track originally...

The ice river for some reason loses all traction sometimes might be animated water below the surface related even though it's UV is flipped. It does make sense a bit so I'll keep it for now.

Thumbnail and magmafalls flow. For some reason you have to copy it 1:1 from how it's in the original.

Hot Top Volcano, no Reverse yet it's a bit hard for the AI to find the 2 holes so I'll have to change the entire hole locations make it wide on the inside smaller on the outside. I'll do that soon. No dino yet either so there's a Diddy instead. Note I barely added any triangles it's purely extracted textures converted and slightly adjusted. No hate on em. I'll fix the other maps later not sure if I let them have natural shadows or no shadows, hard to tell what one is better. DD4 curretly uses Tarmac1's weather and has natural shadows and darkness. I tried the cave without shadows and heavy saturated lighting and it just didn't look right. Also note I tried to do a skybox using objects and it seems to make the map just pure dark with light effects "faking" light, gotta find a better way.

DD2r was broken perhaps it's fixed now?

First 3 maps now have Reverse tracks unfortunatly the boss mountain's checkpoints don't work quite right I'll do that later.

Of course I forgot something
The shortcut over the water isn't reliable, only 5% of bots use it but it sure looks nice and it is a path you can take in the original. Just don't go too fast, or too slow after a few tries it's enjoyable.
One wrong triangle in the second map still I'll fix it with map 3 and 4. 4? Exactly.

AI routes of map 1 and 2 redone, actual weather added and 2 more alternate routes.
