Any modder here able to finish my track?

Hi! I'm the creator of the track PGE Narodowy and just recreated the 2025 Drift Masters layout for round 7 "Grand Finale" but due to poor performance I can't add textures neither port it to Unity for gameplay. the idea is to make it as clean as possible and match the size of the car for drifting events. DM me on Instagram @phon7x_frz and show me your best works.
