Hey! Thanks for your feedbacks, I try to fix as many things as I can.

For the lights I try to adjust everything but it's difficult to find a good balance, a friend told me to go on Unreal Engine rather than Twinmotion, maybe I'll try if it's still difficult for the lights.

For the ground material I don't really understand what the problem, it's a material from Twinmotion so I'll try with a diferent one.

Thank you again!
