I do, thanks.
I removed the alpha layer and the blades returned but look excessively wide. I'm going to play with the different alpha layers and see if I can dial it in.
I am wanting to have the top of the main rotors white and the bottom remain in black.
Thanks for pointing me to "{"uh1_rotor_alfa", 0, "uh_1_blade", false};" line. You are the man.
