Need help to reduce millions of vertices and faces ._

[Megaera]

Hi, I have four files of a hair set separately (eyebrows, eyelashes, ponytail, and main hair).

The problem is that they have too many vertices and faces, causing Blender to crash or run very slowly. I’ve tried using the decimate modifier, but it has a limit, and there are still way too many vertices and faces, and it usually crashes when I try it.

This is only the ponytail.

And this the main hair.

Is there any other way to reduce them so I can work with them with normal performance in Blender?

Thanks in advance <3

Honestly, I’d throw this away and start fresh. It’s not all that complicated, you could whip this out with some curves in an hour or so.

I’m with @Joseph on this, but if you really really want to keep this hair you can separate each object into smaller pieces, decimate them individually, and recombine them after you’re finished. Save frequently in case you accidentally crash again.

Just select an area near the end of a clump, Ctrl+L to select linked, and P to separate.

One thing you can try is to do it in small increments to start. Decimate only by 0.9 and see if it accepts to do it. If it does, apply the modifier, do it again and again at 0.9 until it starts to respond better.

Once you know it works, a trick you can do each time is to disable the visibility of the modifier before you enter the number, or else you will have to wait twice (when entering the number and when applying the modifier).

Once you are at a lower triangle count, you can start decimating by larger amounts.

The question might be:

Why does the source of this provide that much polygons at all ?

(Also: you might have less memory than the provider of this ?? But anyway: why ???)
