This project required Particular and Optical Flares plugins as it said in the description. If you dont have these plugins you can turn off layers which required plugins. Presss “Shy” switch. Then turn off “particular” and “Optical Flares” layers. That will help.

To remove mirroring effect: In “Local Map” composition open “3D” composition and remove “Motion tile” effect from layers 4-12 (Mate-front, mate-side).
