I have too cloth objects, one is a curtain and the other is a blanket. The curtain is locked into a position I like, but when I run the simulation on the blanket it also animates the curtain. So how do I lock the curtains frame so that way when I run the sim it doesn’t switch frames?
Apply the curtain cloth modifier at the frame you want to keep to make it a real mesh (you will lose its cloth simulation)
Im having a hard time understanding what you are saying. But I did apply the cloth modifier. Like you said it resets the frame. Thats not what I need. Im sorry but I think I misunderstood you.
Run the simulation until you hit the frame you like. Then select the curtain, go to the Modifier panel, and click Apply on the Cloth modifier. This should remove the modifier, but set the curtain as it was in that frame.
Unless that exactly what you tried, and I’m misunderstanding, too…?
