i did find Death race car in ketchup site https://3dwarehouse.sketchup.com/model/21848c8bdb0a59daf78a1a0fc1c3959c/Death-Race-mustang from user called Imran and i deside to download it and give it shot with my favorite tools
1- first-thing when i got the model i find it's not quad and was very hard to Unwarp UVW it so i did fully re Re-topology to all car body to be quad
2 - then i did unwarp UVW all parts and send it to Substance painter to make Texture works
3 - i adjust some stuff on 3Ds max and render the car
Hope you like it and thanks
