1) shading is way off. Lower global and increase directional from up.

2) can you hide the tracking points under the wheels?

Rest is great as usual.

Or... Is the car even throwing a shadow?

@LukeAlmighty it is but it's very faint. The day i took the footage was a bit cloudy an the shadows were very soft, i used an hdri that more or less matched the lighting situation

@LukeAlmighty 1. Noted thanks, i forgot also yo use a 360 image from yhe site as reflection sso it uses the hdri ones.

2. I could... in the end i didn't used them, i don't tknow if my choice of markers is wrong or the video quality is very poor, but i ended up bruteforcing the whole tracking thing and i let ble der recognize features automatically.
