FBX size limit?

I have an FBX that is about 200 megabytes big with about 500 animations in it. Unity will not load it, and essentially freezes. Unity has built a .meta file for it, but still sits doing nothing for hours trying to read it while Task Manager insists Unity is working really hard at “something”. Is there a limit to the size of an FBX file that Unity can handle? If so, why does Unity try to load something it knows is too big every time I open the program just so it can freeze?

So don’t put something too big in. Anything that has over 65,000 polys needs to be split, and this will take a long time to import.

Well, it’s not a model, it’s just a skeleton with 500 animations. It is a lot of animations, though. I can open the individual animations without it freezing, but I can’t select the FBX.

Hi Pregga, I am looking to bring in a small model with a ton of animations as well.

  • How did you fix it?
  • Was there a ceiling you found for the fbx import size that you could stay under?
