Hello :)
I made a cloth simulation with colissions that looks great on the viewport but when rendering it becomes weird . The animation its about a girl who opens her closet and a bunch of clothes fall. I´ve tried baking all dinamics before rendering but no changes. And also have to say I have some clothes hanging inside the closet that dont have any modifiers
That is a complex setup to troubleshoot over text. I suggest you try rendering one piece of trouble clothing at a time. Turn everything else off, focus on one model and starting changing parameters and see what is going on. Rendering will be quicker for best feedback speed and once you hit the problem the solution for other meshes will probably be the same.
